[4 Quick DIY Fixes] Generator only Runs on Choke / Half-choke!

As a general rule, the reasons a generator will stall when the choke is turned off are due to stale fuel, a clogged or restricted main jet, a clogged or restricted pilot jet, a loose fitting carburetor, or damaged carburetor gaskets. When the choke is turned off, the carburetor allows more airflow into the combustion chamber. If the air-to-fuel ratio is not correct when this takes place, then stalling will occur. This can be a fuel problem or an airflow problem. https://homebatterybank.com/quickly-fix-a-generator-that-only-runs-on-choke-half-choke/
