Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| ENGINE WILL NOT TURN OVER | Restricted air intake. Internal seizure. Loose connections. Engine oil too heavy for low temperature. Battery discharged. | Clean air cleaner. Check, disassemble and repair. Tighten connections. Change oil if necessary. Recharge. |
| ENGINE CRANKS TOO STIFFLY | [oil in crankcase too heavy for low temperature. Load connected. Defective decompression release. Worn or damaged fuel transfer pump. Air leak in fuel lines. Clogged fuel lines. Fuel tank too far below engine. | Check oil specification, change oil if necessary. Disconnect load. Check and adjust decompression release. Replace or rebuild pump. Tighten all corrections, check for defects in lines. Clean fuel lines. Ensure fuel tank is no more than 6 ft. below engine. |
| DEFECTIVE BATTERY | Check starter circuit. Adjust starting procedures, check for causes of hard starting. Clean battery top if dirt and electrolyte are present causing constant drain. | |
| ENGINE TURNS BUT WILL NOT START | [Defective glow plug or preheater. Defective fuel system. Air in fuel system. Faulty injection caused by dirty fuel or clogged fuel filter. Poor compression, wrong timing, poor quality fuel, hardened plates (sulfation) due to low charge after long period, loss of active material, broken terminals. | Repair or replace glow plug or preheater. See Fuel System Section for further issues. Bleed fuel system if air is present. Replace with clean fuel and clean primary fuel filter, replace secondary filter if clogged. Check compression and adjust timing if necessary. Drain and fill with fresh fuel if poor quality fuel is the issue. Replace battery and check new battery charge condition at frequent intervals. Inspect for broken terminals. |
| ENGINE MISFIRES AT ALL LOADS | [Poot compression. Broken valve spring. Defective or dirty nozzle. | See Poor Compression section. Replace broken valve spring if necessary. Clean or replace defective nozzle, clean fuel system. |
| ENGINE MISFIRES AT LIGHT LOAD | [Faulty injection. Poor compression. | Inspect fuel system for faulty injection issues. Check and address poor compression if present. |
| DEFECTIVE NOZZLE (Usually Indicated by Defective Spray Pattern) | [Dirt in nozzle. Externally carboned nozzle. Worn nozzle or valve. Incorrect nozzle opening pressure. | Clean nozzle, check filters and fuel quality if necessary. Clean outside surface of nozzle if externally carboned. Replace or repair injection nozzle as needed. Adjust nozzle pressure to correct specifications. |
| FUEL KNOCK | [Engine misfires at heavy load. Dirty air cleaner. Dirty fuel filter. | Clean air cleaner and inspect exhaust line for restrictions if necessary. Clean primary filter, replace secondary filter cartridge if clogged. |
| LOW ENGINE POWER | [Restricted air intake. High exhaust back pressure. Thin air at high altitude or in hot weather. Fuel line leaks. Poor compression. Incorrect timing. Injection nozzle sticking. Injection nozzle spring broken. Air leaks in fuel lines. Poor fuel. | Clean air cleaner if restricted intake is the issue. Inspect and address exhaust line restrictions if present. Check for thin air conditions at high altitude or hot weather. Inspect fuel system for leaks, replace faulty components as necessary. Address poor compression issues by checking and adjusting timing. Clean nozzle to prevent sticking. Replace broken spring in injection nozzle if applicable. Repair or replace any leaking fuel lines. Ensure proper fuel quality. |
| OIL SYSTEM | [Diluted oil due to leaky fuel transfer pump diaphragm. Faulty cylinder oil control. | Rebuild or replace pump if diaphragm is leaking. Inspect rings and cylinder walls for issues related to faulty cylinder oil control. |
| Leaking oil seals | Inspect crankshaft front and rear oil seals | |
| Leaky oil base gasket | Check for leaks around gasket. Replace if necessary. | |
| Sticking compression ring | Replace | |
| Defective breather valve | Clean the valve or replace it. | |
| ENGINE STOPS WHEN START SWITCH IS RELEASED | Centrifugal switch remained open (units with revolving field generator) | Clean and adjust |
| ENGINE RUNS BUT VOLTAGE DOES NOT BUILD UP | Poor brush contact, Open circuit, short circuit, or ground in generator, Residual magnetism lost | See that brushes seat well, are free in their holders, are not worn too short, and have good spring tension. Replace parts necessary. Consult your dealer |
| ENGINE STOPS UNEXPECTEDLY | Fuel tank empty, Transfer Pump failure, Safety switch operated (where used) | Refill, Repair or replace, Correct the overheating or lubrication failure. Press reset switch |
| DULL METALLIC THUD. IF NOT BAD, MAY DISAPPEAR AFTER FEW MINUTES OPERATION. IF BAD, INCREASES WITH LOAD | Loose crankshaft bearing | Replace unless one of the next two remedies permanently corrects the trouble. |
| SHARP METALLIC THUD, ESPECIALLY WHEN COLD ENGINE FIRST STARTED | Low oil supply, Oil badly diluted | Add oil, Change oil |
| TAPPING SOUND | Valve clearance too great, Broken valve spring | Adjust. Replace faulty valve system, Install new spring |
| HOLLOW CLICKING SOUND WITH COOL ENGINE UNDER LOAD | Loose piston | If noise only slight and disappears when engine warms up, no immediate attention needed. Otherwise replace worn parts |
| LIGHT POUNDING KNOCK (KNOCK FROM FIRING OF FUEL IS NORMAL) | Loose connecting rod bearing, Low oil supply, Oil badly diluted | Adjust or replace, Add oil, Change oil. Investigate cause |
| ENGINE RACES | Too much fuel injected. | Check governor performance and linkage condition |
| ENGINE MISFIRES | Faulty injection, Low compression | Clean fuel system. Use clean recommended fuel, Tighten cylinder head. Service valves and piston rings as needed |
| LOW OIL PRESSURE | Defective gage, Oil too light or diluted from leaking fuel pump diaphragm, Oil too low, Oil relief valve not seating, Badly worn bearings, Sludge on oil cup screen, Badly worn oil pump | Replace, Drain.
