Well, now it wont even crank. I swear, I have been working on this thing for 7-8 YEARS now, I get it running perfect, and then suddenly it wont run at all. Cleaned the carb to a point that I dont see any way it can be the problem. Replaced the intake and all the gaskets. Points....... Time after time. Had it where you could stand beside it and crank the key, with the tractor in gear, and it crunk instantly and would roll away. After a bad storm a month or so ago I used it to haul away blown over trees, and it never missed a beat. Put the deck back on and started mowing and suddenly, it wont even run anymore. VERY discouraging against onans.
