Frequently Asked Questions
How do I test a carburetor cut solenoid?
Remove the solenoid from the carburetor and test it with a 12-volt battery - if it actuates, it is working.
Where does this solenoid sit?
It threads into the carburetor on its circuit; match the exact solenoid to your carb using the photos and check the wiring is intact.
What causes a cut solenoid to fail?
Age, a corroded terminal, or a burned coil - a dead cut solenoid causes run-on when you switch off or a rough idle.
