Also at mid-full throttle the governor moves erratically "hunts".

I pulled the carb off and there was some gunk in the float bowl, I cleaned that out and made sure the throttle and choke butterfly's were clean and moved freely.

It seems like I'm not getting enough fuel. With nearly no air entering the carb it will stay running, as soon as you unblock the carb or slightly open the choke (even with the carb blocked) the engine dies.

My guess at this point is that the main mixture "jet" may have a blockage, therefore not delivering enough fuel.

Anyway thanks for your time/advice.
Did you leave gas in it for a bit without the anti-gunk stuff. Those who don't live in FL don't realize how quickly the ethanol can congeal down here. I use ethanol free gas for my equipment.

I had to do a rebuild on one of mine, but it was a much smaller engine (a pressure sprayer).
