damn, i'm an idiot..
i have a 40/41 sprocket that is about 9" and i asumed it was 72 teeth(i was going by memory from about 3 years ago when i bought it) anyway i was trying to get something smaller because as you two pointed out it is to:censure:big... i got over my lazyness and counted it and its a 55 tooth:doah:
well i'm gonna have to regroup on this deal, tonight i tryed to put the flathead briggs in my bike tonight and it wont fit without changing tank and carb setup.. i thought i could just through something together with the stuff i have, but of coarse it never works out that way!!
somebody delete this wanted add please
