I recently met a gentelman that works on mowers that has 8 lawnboys!!!! None run but he hates to work on them and has offered me 7 if I fix one. I have 3 on hand, a 10323, 680540, 10304. The mower that I needed to fix was done in 30 minutes. I have the 10304 running but it doesnt seem to get up to full rpm's. I cleaned the carb and everything seems to look clean. When I move the govener fin it doesnt seem to affect the rpms that much. Is there some other item that I am overlooking?
