How bad?

[Tim Bozeman]

I was shredding yesterday when I heard a pop and the motor started running away(faster than governed full throttle) I controlled the motor speed by choking the motor until I could get to a place to shut doen. I checked the linkages everything looked ok, so i restarted, and it tried to run away again, i pushed the cark linkage to the idle position and it would idle as long as I held it. I finally was able to finish the job by using the engine speed lever as though it was teh throttle plate, if i moved it much past idle it would run like it was on a drag strip, if I pushed it all the way to slow it would slow down. When I hit thick patches I would have to goose the throttle to have enough power to get through without stalling.

I'm guessing that all this leads to a Govenor rebuild.... any ideas what may have broken or any other things I should check?

BTW, this is a 9n with a Sherman OD and 12v coversion

Tim, sounds like you're on the right track with a governor rebuild. It's hard to know what you've got until you tear into it.

What caused the "pop" will likely become apparent once you open it up.
