I managed to get the governor assembly out this afternoon. Boy that was a tight squeeze! I had to drop the rear of the transmission and wedge it over to the side with a block of wood in order to provide enough space to remove it. It doesn't look dirty, but who knows? I'll wash it down really good and make sure that it moves freely before I put it back in. Is there anything thing else that I should do to it or the transmission while I have it out?
