| Symptom | Cause | Remedy |
|---|---|---|
| Engine cranks slowly or not at all | Poor battery connections | Clean and tighten the positive (+) and negative (–) battery connections at battery and engine |
| Engine cranks slowly or not at all | Battery is not fully charged | Recharge the battery |
| Engine cranks slowly or not at all | Electric starter is faulty | Check starter brushes and bearings |
| Engine cranks slowly or not at all | Improper engine oil | Change oil having the proper viscosity for the ambient temperature |
| Engine cranks slowly or not at all | There is a load on the engine | Remove load and retry |
| Engine cranks slowly or not at all | Back pressure. There is excessive back pressure due to a plugged or bent exhaust pipe | |
| Engine cranks but fails to start | Damaged spark plug(s) | Check the spark plug gap. Check for a bad insulator on plug and replace if damaged. Clean carbon deposit from electrode. If wet, dry electrode |
| Engine cranks but fails to start | Fuel Supply | Check fuel supply and shut-off valve. Check fuel filter and clean if dirty. Check all fuel hoses for crimps and clogging. Check connections into carburetor for air leaking in |
| Engine cranks but fails to start | Fuel. Gasoline may have water mixed in or the gasoline grade is not correct | |
| Engine cranks but fails to start | Carburetor problems. Carburetor is flooded and may have bad floats or the floats are stuck. Carburetor has varnish deposits built up and requires disassembly and cleaning | |
| Engine cranks but fails to start | Governor and throttle linkage | Check linkage connections. Check tension in springs. Check governor, throttle and speed adjustments |
| Engine cranks but fails to start | The fuel cut-off solenoid is faulty | Check for loose or damaged wires and connectors. Check voltage levels at the connector to the solenoid. Replace harness or solenoid |
| Engine cranks but fails to start | Dirty air cleaner | Check air cleaner and service if dirty |
| Electric starter does not operate | Key or start switch | Check wiring connections and switch |
| Electric starter does not operate | No continuity between the key switch and the starter | Replace wires |
| Electric starter does not operate | No continuity between the battery and starter | Replace cable |
| Electric starter does not operate | Low battery | Change or recharge battery |
| Electric starter does not operate | Starter solenoid is bad | Check voltages, clean, repair or replace |
| Electric starter does not operate | Starter motor is bad | Check brushes and wiring, repair or replace |
| Electric starter does not operate | Engine seizure. The crankshaft has seized or the piston and cylinder have seized | Check crankshaft bearings and bearing surface |
| Electric starter operates but engine does not start | Low fuel | |
| Electric starter operates but engine does not start | Poor wiring connection or no continuity of ignition system | Check wiring connections and ignition coils for a short |
| Electric starter operates but engine does not start | Electric starter is bad. Slow cranking RPM is caused by low voltage at starter or worn brushes or bearings | Repair or replace |
| Engine Overheats | Air flow is obstructed at inlet or cylinder baffle | Clean out debris in baffle |
| Engine Overheats | Improper engine oil | Replace oil |
| Engine Overheats | Lean air/fuel mixture | Check for plugged passages in carburetor |
| Engine Overheats | Excessive back pressure on exhaust | Check muffler and spark arrester |
| Engine Overheats | Engine is overloaded | Change to rated load |
| Engine Idles Rough | Low idle speed | Adjust idle on carburetor |
| Engine Idles Rough | Air is mixing at air intake connection | Check, tighten or replace gasket |
| Engine Idles Rough | There is blow-by on the head gasket | Replace the gasket |
| Engine Idles Rough | Improper valve clearance | Adjust clearance |
| Engine Idles Rough | Excessive clearance between valve stem and |
