All three lawnmowers had carb issues because of stale fuel. I got them all running. I have one problem with one of the HR214's. The governor is stuck wide open. I looked at it briefly last night. Is it possible I have an air leak somewhere causing this? I cannot seem to find a ajustment that cures the problem. I runs like a striped ape, but I bet it won't last long at 5000 rpm. I did not let it run long.
