Toro Proline lawn mower Problem, surging?
I have a 13 hp Kohler command pro engine on a proline, relatively new, that at high speed, it surges. All fuel and air passages are clean, proper sparkplug and gap, clean fresh fuel, float setting correct, governor adjusted to fact. specs., there is only a low speed carb.needle, does not have or need a fuel pump,(gravity feed) and a Walbro carb.
Anyone have any suggestions?
Boomer, I said all the passages are clean, I've already had the carb. apart, that's how I know the float setting is correct.
hi rob sounds like you almost covered all the bases good job! what i would recommend is getting a card kit and clen the carb with carb cleaner and reinstall. it could be just a piece of dirt in the jet. good luck :0)
