Tecumseh Troubleshooting - It Runs, But Not Well

Published at : 23 Dec 2025

Jason picked up this 10hp Tecumseh powered Western Hemisphere generator for $33. The engine is not stuck and I feel compression. It should run, but how well and will it make power?

I no longer use Harbor Freight Super Heavy Duty Degreaser in my ultrasonic cleaner. Harbor Freight changed the recipe. The bottle previously stated "NON-CORROSIVE". Now it says "CORROSIVE", "do not user on Aluminum". It now damages most carburetors. Recently I have been using Simple Green PRO HD with good results.
