Working on the wife's 52 TO30. The tractor revs through the roof with the slightest pull (just a few degrees). Pulled the carb. Cleaned throughly in an ultra sonic cleaner. Blew out all passages, verified float height was correct. Put it back on tractor and adjusted the throttle and governor linkage. Air screw out 3/4 main between 1 3/4- 2 turns out Starts and idles much better but still over revs at the slightest throttle increase. Sprayed starting fluid around the carb and intake manifold looking for a possible leak. The engine stayed on idle and did not surge I removed the throttle rod between the carb and governor. The governor arm does not move when it throttles up. So tomorrow morning the front cover is coming off. Will it be obvious that it needs replaced? What should I be looking for?
Thanks in advance for your help.
