damaged spark plug.
3. Defective spark plug cap.
4. Old or low quality gasoline.
5. Incorrect compression.
1. Check cap and wire connections.
2. Re-gap or replace spark plug.
3. Replace spark plug cap.
4. Use only fresh 87+ octane stabilizer-treated
unleaded gasoline.
Do not use gasoline with more than
10% ethanol (E15, E20, E85, etc.).
5. Diagnose and repair compression. (Use Engine will
not start: COMPRESSION RELATED section.)
Engine stops suddenly 1. Carbon Monoxide level high. Red light
on Carbon Monoxide Sensor illuminates.
2. CO Sensor Alarm flashes yellow
continually shortly after starting.
3. CO Sensor Alarm flashes yellow
continually after longer period of operation.
4. Low oil shutdown.
5. Fuel tank empty or full of impure or low
quality gasoline.
6. Defective fuel tank cap creating
vacuum, preventing proper fuel flow.
7. Faulty magneto.
8. Disconnected or improperly
connected spark plug cap.
1. Leave area immediately and allow area to ventilate
thoroughly. Only operate generator outside.
2. Carbon monoxide sensor malfunction.
Sensor needs service. Call 1-888-866-5797 as
soon as possible. Do not use the Generator
until the sensor is working properly.
