Troubleshooting
45Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Lead deposits tend to build up in the combustion chambers. | Use of leaded gasoline. | Use clean, fresh, no lead or low-lead gasoline. Regular grade gasoline may also be used but not highly leaded premium types. For new engines, use nonleaded gasoline. For older engines that have previously used leaded gasoline, remove all lead deposits from the cylinder heads before switching to nonleaded gasoline. |
| Preignition can occur causing engine damage. | Not removing lead deposits before switching from leaded to non-leaded gasoline. | |
| Erratic operation of the generator set. | Operating the generator set from a tee in the main fuel line. | The set's fuel pump has neither the capacity nor the power to overcome the draw of vehicle engine fuel pump. |
| Operating problems due to the fuel system. | Check the fill cap to make sure the vacuum and pressure relief valve is working properly. | |
| Low or Discharged Battery | Faulty Starter, Faulty Start Solenoid | |
| The speed may remain about the same or increase when the load is applied, resulting in a frequency 1 or 2-cycles Aigker than the no load frequency. | If the rise in frequency is more than 2-cycles, lessen the internal spring tension. If there is a drop in the frequency, increase the booster internal spring tension. To increase the tension, pull out on the spring bracket, and move the pin to a different hole. | |
| Engine will not start when cranked | Battery discharged. Loose connections. Defective starting circuit. Defective switch. | Refill tank. Check fuel system. Clean, adjust, as necessary. Crank few times with spark plugs removed. Drain, refill with fresh fuel. Tighten cylinder heads & spark plugs. Reset breaker points. |
| Engine cranks too stiffly | Too heavy oil in crankcase. | Drain, refill with lighter oil. |
| Hot crank | Lack of fuel or faulty carburetion. | Tighten connections. Clogged fuel screen. Repait or replace as necessary. Cylinders flooded. Replace. Poor fuel. Poor compression. |
| Excessive oil consumption, light blue smoky exhaust | Oil leaks from oil base or connections, This does not cause smoky exhaust. | Check breather valve. |
| Engine misfiring. | Faulty ignition. | Clean, adjust, or replace spark plugs. |
| BLACK, SMOKY EXHAUST, EXCESSIVE FUEL CONSUMPTION, FOUCING OF SPARK PLUG WITH SOOT, POSSIBLE LACK OF POWER UNDER HEAVY LOAD | Fuel mixture too rich. | Adjust carburetor or choke. Install needed carburetor parts. |
| Engine stops unexpectedly. | Fuel tank empty. | Fill with fresh fuel. |
| SHARP METALLIC THUD, ESPECIALLY WHEN COLD ENGINE FIRST STARTED | Low oil supply. | Add oil. |
| Oil badly diluted. | Change oil. | |
| PINGING SOUND WHEN ENGINE IS SUDDENLY OR HEAVILY LOADED! | Wrong spark plug. | Install correct spark plug. |
| Spark plug burned or carboned. | Install new plug. | |
| Fuel stale or low octane. | Use good, fresh fuel. | |
| LEAN FUEL MIXTURE. | Clean or adjust carburetor. Clean intake air line. | |
| LIGHT POUNDING KNOCK | Inspect linkage and setting. | Clean & adjust carburetor. |
| Low air supply. | Add oil. Change oil. | |
| ENGINE MISFIRES AT LIGHT LOAD | Spark plug gap too narrow. | Adjust to correct gap. Tighten or replace manifold and carburetor gaskets. |
| INTAKE AIR LEAK. | Tighten or replace manifold and carburetor gaskets. | |
| FAULTY IGNITION. | Clean, adjust or replace spark plugs. Tighten cylinder head & spark plugs. Grind valves. | |
| LOW COMPRESSION. | Tighten cylinder head & spark plugs. Grind valves. | |
| ENGINE MISFIRES AT HEAVY LOAD | Spark plug gap too wide | Adjust gap |
| CLOGGED CARBURETOR. | Clean, adjust or replace spark plugs. Clean jet and adjust carb. | |
| CLOGGED FUEL SCREEN. | Clean, adjust or replace spark plugs. Clean jet and adjust carb. | |
| ENGINE BACKFIRES | Lean fuel mixture. | Clean or adjust carburetor. |
| ENGINE RACES | Governor not controlling carburetor. | Check governor performance & linkage condition. Refill with good, fresh fuel. |
| LOW OIL PRESSURE | Defective gage. | Replace. |
| Oil too light or diluted from leaking fuel pump diaphragm. | Drain. Refill with proper oil. Repair or replace fuel pump. | |
| Oil taa low. | Add oil. | |
| Sludge on oil cup screen. | Clean screen & air sump. | |
| Badly worn oil pump. | Replace. | |
| HIGH OIL PRESSURE | Defective gage. | Replace. |
| Oil too heavy grade. | Drain. Refill. | |
| Clogged oil passages. | Clean all lines & passages. | |
| Oil relief valve stuck. | Clean by-pass. Replace if needed. | |
| ENGINE OVERHEATING (Approximasely 60°F higher than ambient) | Overloaded. | Reduce load. |
| VOLTAGE LOW AT FAR END OF LINE BUT NORMAL NEAR POWER PLANT | Too small line wire for load and distance. | Install larger or extra wires. Or reduce load. |
| ELECTRIC MOTOR RUNS TOO SLOWLY AND OVERHEATS AT FAR END OF LINE BUT OK IF USED NEAR POWER UNIT | Too small line wire for load and distance. | Install larger or extra wires. Or reduce load. |
| VOLTAGE UNSTEADY BUT ENGINE NOT MISFIRING | Speed too low. | Adjust governor to correct speed. |
| Loose connections. | Tighten connections. | |
| Correct any abnormal load condition causing trouble. | Write a letter to the same address stating the reason for returning the part. |
