Add fuel stabilizer to the gasoline or the Warranty is VOID. Note: Do not use gasoline that has been stored in a metal fuel container or a dirty fuel container. It can cause particles to enter the carburetor, affecting engine performance and/or causing damage. 3.
Spark Plug Maintenance Spark Plug Cap Safety 1. Disconnect spark plug cap from end of plug. Clean out debris from around spark plug. 2. Using a spark plug wrench, remove the spark plug. 3. Inspect the spark plug: If the electrode is oily, clean it using a clean, dry rag. If the electrode has deposits on it, polish it using emery paper. If the white insulator is cracked or chipped, the spark plug needs to be replaced.
Pump Troubleshooting 1. Incorrect lubrication or not enough lubrication. 2. Worn parts. 1. Low engine speed. Unit stalls 2. Severely clogged air filter. 3. Improper lubrication. 1. Pump is not primed. 2. Intake Strainer clogged. 3. Air leak at intake connector. 4. Hose leaks. Pump does not 5. Suction hose has pump water collapsing wall. 6. Hose has too small diameter. 7. Pump is too high above water surface. 1. Suction hose collapsed, damaged, too long or diameter is too small.
Troubleshooting Problem Engine will not start Possible Causes Probable Solutions Safety FUEL RELATED: FUEL RELATED: 1. No fuel in tank or fuel valve closed. 1. Fill fuel tank with fresh 87+ octane stabilizer-treated unleaded gasoline and open fuel valve. 2. Choke not in CHOKE position, cold engine. 2. Move Choke to CHOKE position. 3. Gasoline with more than 10% ethanol used. (E15, E20, E85, etc.) 3. Clean out ethanol rich gasoline from fuel system. Replace components damaged by ethanol.
1. Spark plug cap loose. 1. Check wire connections. 2. Incorrect spark plug gap or damaged spark plug. 2. Re-gap or replace spark plug. 3. Defective spark plug cap. 3. Replace spark plug cap. 4. Old or low quality gasoline. 4. Use only fresh 87+ octane stabilizer-treated unleaded gasoline. Do not use gasoline with more than 10% ethanol (E15, E20, E85, etc.). 5. Incorrect compression. 5. Diagnose and repair compression. (Use Engine will not start: COMPRESSION RELATED section.) 1.
