Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Did you go into the engine, and physically looked at the governor?
Do you get any push/pull from the governor lever and shaft?
sounds like the internal governor parts are the problem. Either governor, or the arm it has to push.
If no push pull from lever, problems internal.
Will not be spring!
The push / pull has to come from the governor lever!
The governor wieghts have to move out, and push the top hat piece of the governor against the inner governor lever. The lever is part of the shaft.
If the governor shaft fell out, it is broken internally.
