Long winded answer to your short winded problem! I was in your situation about 18 months ago (except for wanting to convert to 12 v...bahhh.) Anyway, Molly's problem turned out to be restricted fuel flow even though I was pretty-well convinced the flow was ok; the bowl never looked low, but apparently doesn't need to to affect running. The flow was just enough for the engine to start, run for a while and die. If I'd jump off the tractor just as it died and checked the carb float bowl, by the time I'd get there it would be full. In desperation I emptied and cleaned fuel tank, blowing out and/or replacing all the filter screens (in-tank, sediment bowl, carb) and blowing out the fuel line itself. In my case, the culprit turned out to be a small round seed lodged in the pipe from the tank to the sediment bowl; once that blew out (hi-pressure air), she runs great and (knock wood) hasn't slowed down since. So I'd suggest a thorough cleaning of entire fuel system. good luck, Tom & Molly (8N 118021)
