Temp cure is to loosen the mounting screws (two philips heads) to free up the throttle shaft so the governor works. That allows it to be used but the engine revs back and forth telling me the shaft is still a bit sticky. Any looser bolted to the motor and it will suck air at the gasket and not run right.
What to do...
Option 1, sand the carb flange with 1000 grit on a flat surface to make sure it is flat (like milling a car motor head) ? Over-bore the throttle shaft ever so slightly so if the carb flange warps when tightened it won't seize the shaft? Widen the venturi around the butterfly so if it is seizing when the carb is tightened it won't seize? All the above?
I'm tired of f****ng with this POS. My kid mowed this morning and except for the wide open initial rev (2 seconds) when started and the govenor oscillation when there is no load on the motor, it actually ran well. But i know as soon as it sits for a while, maybe a week or two, I'm going to have to f*ck with it again.
Your thoughts (besides buy a new mower);
