So I have a 2 speed that will, after about 10-15 minutes bog out if I give it any more than like 1/5th or 1/4th throttle. I dont know why it does this since the carb is good, and running fine (chocolately plug). Would it have something to do with the tranny perhaps? It seems to be like a vaccum leak in the carb/intake area but it always starts up fine, and runs for a bit if its been sitting for a long time.
oh also as soon as it starts doing this the idle will change from normal to very high. Pushing down on the choke seems to get rid of the problem, is there some reason that it would develop a leak when its warmed up?
