[79t/a]

i have a 7 hp tecumseh off a ariens snow blower but the carb that was on it was screwed up but i put a diff 1 on it from a 5 hp and it runs but has no topend and runs too lean but i got an adjustable 1 like the stock 1 i got it running tuned it and after about 20 min of running it died and would not start but the carb works good on 2 diff motors wat is going on also its on a gocart
thanks steve
