The pressure shouldn't drop off rapidly after priming has stopped. On gaseous fuel systems, periodic service should include cleaning or replacing the air cleaner, carburetor adjustment, inspection of hoses, etc. Next, [un the engine at governed speed on the fuel remaining in the carburetor and measure the fuel pump pressure developed.

Pressure should be between 2 and 3 psi with the gauge held 16 in. If the reading is above maximum, the diaphragm is probably too tight or the diaphragm spring too strong. Overhaul the pump and replace the defective parts.

Low pressure with little or no pressure leak after pumping stops indicates a weak or broken spring or worn linkage and in most cases the pump should be replaced. In this case, install a new pump. Removol and Disassembly Fig. Remove the pump inlet and outlet. Notch the pump cover and body with a file for assembly in the same relative position, and remove the six screws Assembly: 1.

Before installing a new diaphragm, soak it in fuel. Tap the body with a screwdriver to separate the two parts. Don't pry them apart - this may damage the diaphragm. Lift out the diaphragm assembly and diaphragm spring. Compress the rocker spring and install between the body and rocker arm. Assemble the cover to the body with notch marks lined up. Install the screws but don't tighten. Push the rocker arm in full stroke and hold in this position to flex the diaphragm.

NOTE: The diaphragm must be flexed or it will deliver too much fuel pressure. A kit is available for replacement of these parts. Because the extent of wear cannot easily be detected, replace all parts in the kit. If the diaphragm is broken or leaks, check for diluted crankcase oil. Tighten the cover screws alternately and securely, then release the rocker arm.

Install the pump on the engine and repeat the pressure test. Remote starting plants use an automatic electric choke Fig. Berare the plant starts, the choke is partially closed. When the plant has started, the generator supplies current to the heatH iog element which heats the biHrnetal coil, opening the choke plate. Adjustmenf, Electric Choke: Under normal operation, adjust the choke so the distance measured between the choke plate and carburetor throat Fig.

Use the straight shank end of a drill hit to measure the gap. The upturned air cleaner must be removed for choke adjustment. To adjust the choke, loosen the two screws on the endplate and rotate the cover assembly. Operation and Adjustment, Thermo-Magnetic Choke: This choke uses a strip heating element and a heat sensitive biH metal spring to control the choke blade position. A solenoid, actuated during engine cranking, closes the choke all or part way depending on ambient temperature.

The bimetal is calibrated to position the choke to the proper opening under any ambient condition. The choke is adjusted at the factory. If, for any reason, readjustment is required, use the following procedure. Adjustment must be made with the bimetal at ambient tem perature. Do not attempt adjustments until the engine has been shut down for at least one hour. Remove the air cleaner to expose the carburetor throat. Loosen the screw which secures the choke body assembly. Rerer to Fig.

Use a drill hit to measure the choke opening. Rotating the choke body clockwise rich-ens and counterclockwise leans the choking effect. Tighten screw that secures choke body.

H Disassembly and Repair, Electric and ThermoHMagnetic Choke: If the choke does not operate, or will not maintain its adjustment, disassemble it for repair. If it will not close, check for binding, incorrect adjustment, or incorrect assembly of the coil. If it will not open after plant starts, check for heating. The choke should be warm to the touch within a minute or two of plant starting.

To disassemble choke refer to Fig. Check the coil resistance with an ohmmeter. With the element at room temperat'ure, resistance should be about 5 - 6 ohms for volt models, about 25 ohms for volt models and about 16 ohms for volt models.

If the coil is defective, replace the thermostat cover. The resistance should be about If the heater is defective, replace it with a new one. When the start button is engaged, the solenoid should cause the spring-loaded armature to contact the solenoid core. Jf this does not occur, check for broken lead wires or a defective solenoid coil. The solenoid coil resistance should be 2. Assembly Fig. Lead tagged G to ground terminal on coil solenoid. Lead tagged H to either of the HI terminals on the salenoid core.

It consists of three major sections: the bowl and float, idle circuit, and load circuit. Fuel enters the carburetor through the intake valve Fig. The float controls fuel level in the bowl by closing the intake valve when fuel reaches a certain height, and opens it when the fuel level drops. The throttle plate is nearly closed at no load, and the intake manifold vacuum is high. The pressure difference between the manifold and float chamber causes fuel to flow through the idle circuit.

The pressure difference draws fuel up through the hollow center of the main adjusting needle, through passages in the carburetor body to the idle port.

Bleed holes in the main adjusting needle allow air to mix with the fuel. When the throttle is almost completely closed, the fuel passes out through the idle port. As the throttle is opened to increase power, it exposes the idle transfer port and fuel is drawn out through this port also. When the load increases, the engine governor opens the throttle further.

The carburetor air flow increases which produces a low pressure at the venturi narrow section of the carburetor throat. This pressure drop draws fuel up the main nozzle where it mixes with air at the nozzle opening. The main adjusting needle controls fuel delivery. As the throttle opens, the manifold vacuum decreases so the idle circuit becomes less effective. In a certai. The main nozzle won't immediately deliver this increased fuel because the jet is controlled by the adjusting needle.

Adjustment, Gasoline Carburetor: The carburetor should be adjusted in two steps - first the idle adjustment, and then the load adjustment. Don't force the needle valves against their seats. This will bend the needle. Then allow the engine to warm up.

With no generator load, turn the idle adjustment out until the engine speed drops slightly below normal.

Then turn the needle in until speed returns to normal. Carefully turn the main adjustment in until speed drops slightly below normal. Then turn the needle out until speed returns to normal. Start the plant and allow it to warm up. Push in on the governor mechanism to slow the plant down to about - rpm.

Set the idle adjustment screw for even operation so the engine is firing on all cylinders and running smoothly. Release the ,governor mechanism to allow the engine to accelerate. The engine should accelerate evenly and without a lag. Continue until the engine accelerates evenly and without a lag after releasing the governor.

This prevents excessive hunting when a large load is suddenly removed. Removal and Disassembly: 1. Remove the air housing door and top panel, fuel line, governor linkage and electric choke wire.

Remove the two carburetor mounting nuts and pull off the carburetor. Remove the air cleaner adapter and choke from the carburetor. Remove the main fuel adjustment needle begin Spec. R and the float bowl nut and pull off the bowl. Remove the float pin and float. Lift out the float valve and unscrew its seat.

Remove the no load adjusting needle, the load adjusting needle Prior to Spec. R and spring. To adjust float level, bend the ,mall lip that the intake valve rides on. Check the choke and throttle shafts for excessive side play and replace if necessary.

Don't remove the teflon coating on the throttle shaft which reduces wear and friction between the shaft and carburetor body. Assembly and Installation: 1. Install the throttle shaft and valve, using new screws. Install as shown in Fig. On valve plates marked with the HC", install with mark on side toward idle port when viewed from flange end of carburetor. Remove the throttle plate screws and the plate and pull out the throttle shaft.

Install choke shaft and valve. Center the valve in the same manner as the throttle valve Step 1. Always use new screws. Remove the choke plate screws and plate and pull out the choke shaft. Install the main nozzle Prior to Spec R making sure it seats in the body casting. Cleaning and Repair: Soak all components thoroughly in a 4. Install the intake valve seat and valve. Clean all carbon from the carburetor bore, especially in the area of the throttle valve.

Blowout the passages with compressed air. If possible, avoid using wire to clean out the passages. Check the adjusting needles and nozzle for damage. If the float is loaded with fuel or damaged, replace it.

The float should fit freely on its pin without binding. Invert the carburetor body and measure the float level Fig. Install the float and float pin. Center the pin so the float bowl doesn't ride against it. See Fig. Install the bowl ring gasket, bowl and bowl nut and main nozzle begin Spec. The throttle plate is almost closed, so the increased vacuum on the engine side of the carburetor draws fuel through the idle passage. When load increases, the flow of air through the carburetor draws fuel from the main fuel port located at the venturi of the carburetor.

Adjustment: Set the carburetor idle adjustment and then the load adjustment. R Adjust the carburetor in the same manner as the gasoline carburetor. Usually the idle adjustment will have little effect on operation, because of the high plant speed. Remove the air housing door and top panel, the fuel hose and governor linkage.

Remove the 2 carburetor mounting nuts and pull off the carburetor. Remove, the float bowl and main adjustment screw begin Spec. Remove the idle adjustment screw and the main adjustment screw Prior to Spec. Install the load adjusting needle with its spring. Install the idle adjusting screw finger tight. Reinstall the choke and adjust. Repair and Assembly: Clean in a suitable carburetor cleaner and blowout the idle passage.

Check the idle needle for wear or damage and the main adjustment for worn threads. For assembly, reverse the disassembly procedure. To switch operating fuels, make adjustments according to Table I. The combination carburetor consists of both the gasoline and gaseous fuel carburetors on a single casting. Refer to the gasoline and gaseous fuel carburetors for descriptions of operation. Install the air horn assembly and gasket. InstaIl the carburetor on the engine and connect the gasoline inlet, governor mechanism breather hose, and choke.

The demand type regulator opens upon a small vacuum from the carburetor. It supplies fuel on demand and shuts off fuel flow when the engine is stopped. Install the air cleaner and the air housing top and door.

The regulator is simply a diaphragm with linkage connecting it to a valve in the gas line. A small vacuum from the engine moves the diaphragm, opening the delivery valve. The gaseous carburetor contains two major sections, the idle circuit and the load circuit.

Fuel delivery depends on the demand c"reated on the fuel inlet line. A small vacuum on the inlet line opens the fuel regulator, delivering fuel. For no- Testing: Blow into the diaphragm vent hole on the regulator cover; this should open the valve. An audible hiss indicates that the regulator is opening. Use the chart in Fig. Install a water manometer on the inlet side of the regulator to make the fine adjustment.

With the gas on, cover the regulator outlet for a few seconds and then open. If the regulator is leaking, the pressure shown on the manometer will drop slightly or waver indicating that the valve is opening.

Turn the screw inward slightly and repeat the test. Continue until the manometer holds steady as the outlet is closed for a few seconds and then opened. Gas Regulator Garretson : The maximum allowable inlet pressure is 8 oz; minimum, 2 oz. If gas line pressure, is greater than 8 oz. The regulator has an adjustment to contIol the maximum pressure at which the regulator shuts off when there is no demand.

Adjust the regulator for shut off when there is no demand, to prevent gas leaks. If gas line pressure is between 4 and 8 oz. To adjust the regulator, the gas line should be connected and the outlet hose removed. Make a coarse adjustment by turning the adjusting screw inward until the hissing of escaping If this regulator appears defective; either won't open, won't close or delivers insufficient fuel, check the shut off pressure adjustment. A kit is available from ONAN to replace both the diaphragm and valve.

Gas Regulator Algas : The Algas regulator has no adjustments and features a positive lock off if pressure increases ahove the regulator rating. Maximum inlet pressure is 5 psi and minimum, 6 ounces. An optional valve is available with pressure rating to 5 psi. If pressure is over 5 psi 1 psi with optional solenoid valve a primary regulator is required to reduce the inlet pressure. If the inlet pressure is within the required limits and the regulator won't deliver fuel or leaks, disassemble it for repair.

To disassemble the regulator, carefully remove the cover and separate the diaphragm from the cover and body. A kit is available from ONAN to repair the regulator. Solenoid Primer Algas regulator only : Algas regulators use an optional solenoid primer to provide quick engine starting. The primer Fig. It can be adjusted for a rich or lean mixture by loosening the lock nut and turning the primer in or out.

Clockwise richens the mixture. To adjust for proper priming of a cold engine, set the primer so a hot engine one with gas in the regulator-carburetor hose and the carburetor sounds slightly rough and produces slightly dark exhaust after the engine first starts firing. The dry paper type folded paper , moistened foam type synthetic sponge and the oil bath type.

Dry Paper Type: early JB plants only : Remove and clean either by shaking or blowing out with compressed air at least every hours. Don't wash it. When using compressed air, hold the nozzle far enough from the cartridge so it won't rupture. Replace the cartridge at least every hours.

If the paper cartridge has a foam wrapper, 'remove the wrapper before cleaning, wash it in clean fuel, dry and install on the cartridge. Remove the regulator-carburetor hose at the regulator and.

Turn the primer clockwise richer until you can hear a small flow of gas at the outlet. Remove the voltage, connect the hose and attempt to start the engine. If the plant starts within three seconds, the primer is correctly adjusted. If not, remove the hose at the regulator and crank the engine for a few seconds to empty the hose and carburetor of gas and readjust the primer slightly.

Connect the hose and attempt to start. Continue until the engine starts within three seconds from an empty hose and carburetor. When the primer is properly adjusted, be sure the regulator locks off when the unit is stopped. To test the primer, remove it from the regulator, noting the number of turns necessary to unscrew it, and operate the start switch. The plunger must extend out. Foam Type Cleaner: This cleaner consists of a foam element over a metal retainer. Approximately every hr8, remove the foam element and wash it thoroughly in gasoline.

Then dip it in crankcase grade oil and squeeze as dryas possible. The eiement should be replaced only if damaged. The air source is automatically selected by the Vernatherm thermo-static element which operates a shutter in the induction air stream. In some conditions. Mounting depth of Vernatherm adjusts plunger to just touch shutter at 70 0 F. Grease points of contact. Use same crankcase grade oil. When changing oil, inspect the wire screen filtering element and remove any accumulation of lint, etc.

Variations in engine speed changes the position of the governor cup on its shaft. This change is transmitted by the shaft, arm, and linkage to the carburetor throttle lever. Engine speed is determined by the tension on the governor spring. Sensitivity speed drop from no load to full load is con- RNO!! R I'Q More coils give less speed drop from no load to full load greater sensitivity. Speed Adjustment!

Turn nut clockwise to increase speed, counterclockwise to decrease speed.. Also, inspect the governor linkage for binding or excessive slack or wear.

Sensitivity Adjustment Begin Spec. R : Sensitivity no-load to full-load speed droop is adjusted by turning the sensitivity adjusting rachet nut accessible through hole in side of blower housing.

If speed drops too much when full load is applied, turn the rachet nut counterclockwise to increase spring tension and compensate for reduced rpm. An oversensitive adjustment, approaching no speed drop when load is applied, may result in hunting condition alternate increase and d-ecrease in speed. Beginning Spec. R the sensitivity is adjusted with an adjusting ratchet. Speed Adju stment Prior to Spec. R : To adjust the governed speed, hold the governor spring stud in position and turn the governor spring nut with a wrench.

For accurate speed ad justment, use a reed type frequency meter on the generator's AC output. A mechanical tachometer can be used, but is not as accurate. Set speed according to Table 2. M Sensitivity Adjustment Prior to Spec. R : To adjust the sensitivity turn the governor spring stud; counterclockwise gives more sensitivity, less speed drop. If the governor is too sensitive, a hunting condition occurs alternate increasing and decreasing speed , Adjust for maximum sensitivity without hunting; see Table 2.

After sensitivity adjustment, the speed may require readjustment. After adjusting speed and sensitivity, replace dot button in blower housing air cooled units only and secure speed stud lock nut. If the governor is either too sensitive or not sensitive enough and can't be adjusted with the stud or ratchet, the sensitivity can be coarsely adjusted by changing spring attachment on the governor arm. Moving this point further from the governor shaft decreases the governor's sensitivity.

TABLE 2. The oil system includes an oil intake cup, gear type oil pump, by-pass valve, oil pressure gauge, full-flow oil filter, and crankcase passages gine is at operating temperature.. If pressure drops below 20 psi at governed speed, inspect the oil system for faulty components. Oil is held in the oil base, drawn by the pump, and delivered MAINTEN ANCE Periodic oil system maintenance should include changing crankcase oil, cleaning the crankcase breather, cleaning rocker box oil lines and replacing the oil filter.

Lines leading to the rocker housing, drillings through the crankcase to the crankshaft bearings and camshaft front bearing, crankshaft passages to coo- necting rod bearings and connecting rod passages to piston pin bushings complete the oil system plumbing.

Because it aids oil consumption control, the crankcase breather is incl uded in this system. Removal: 1. Remove the gear cover and oil base Refer to Engine Repair Section. Unscrew the intake cup from the pump. Remove the crankshaft lock ring and gear retaining washer.

Loosen the two capscrews holding the pump and remove the pump. SKU: Calculate Shipping. Location: Kent. WA Item Description.
