What to do when your Okuma generator's engine won't stay running

• Check the oil. Most generator engines use a low oil level switch to shut off the engine when it detects low oil level. Add oil to the engine if oil level is low.
• Fuel system problems often cause the engine to stall, so you'll need to rebuild or replace the carburetor if it won't stay running.
• Stale gasoline can also cause the engine to stall. Replace the fuel in the gas tank with fresh gasoline.

How to troubleshoot your Okuma generator when the engine won't start

When you can’t start your generator's engine, make sure the tank has fuel and that the fuel is fresh; stale fuel can become watery and won’t ignite well. Tune up the engine to give it the best chance of starting. Check the spark plug and replace it if it’s covered with oil or other deposits.

If your generator uses a battery, charge or replace the battery if it won’t power the starter to spin the engine. If you have to pull the starter rope to start the engine, replace the recoil starter if it doesn’t spin the engine when you pull the rope. Replace the starter rope if it’s broken.

Some generator engines have a low oil level switch that prevents the engine from starting and running if the engine's oil is low. Check engine oil level and add oil if needed.

Test the ignition system using a spark plug tester. Replace the safety switch or the ignition coil if the spark plug isn’t getting current through the ignition system.

Carburetor problems often prevent your generator's engine from starting. Replace or rebuild the carburetor if it’s clogged.

Check your owner's manual for additional troubleshooting tips to help you get the engine started.
