Some of you may have seen my videos on the worn governor shaft bushing on my Tecumseh 12.5 hp OHV engine. Well, I was using it to mow my lawn today and it seemed to be running lean: it was bogging down under heavy loads (aka mowing really long grass). I got thinking about how much the throttle lever was bouncing around in those videos. Anyway, I think my throttle shaft bushing may be worn out. What say yea all, after watching this video? If it is, how would you fix it? p.s. that's carb cleaner I'm spraying.
