Thanks fellas...yes i had my go around with the butterfly screws already..if you read the beginning of this thread it talks about how when i first bought the tractor it was running lean and the head gasket was leaking..i just needed to get it through winter for plow duty...when i pulled the head i found the series of events; screw from throttle butterfly came out and got eaten, blew out gasket, plate hanging up in venturi bore..glad it was brass...i dont know how long p.o had it that way but i dont think the tractor was run much, but i put in new stainless ones, loctited(red) and nutted on the back...couldnt find a way to peen them over, or brass ones..but this throttle shaft has the 30+yr slop in it, and as im about to pull motor for rebuild i would like to snug it up..so these bushings; just drill out to?? And then press in bushing, and then put the shaft in?? I thought there was an oversized shaft available?? I do like the idea and price of the hardware store bushing though..does everyone agree that the "ebay" (you know what i mean) kits are a good buy?? I would really like to do the "new style" piston and rod, and machine for bearing inserts as dbuck suggested, but if those kits are real good, im all about saving some money....thanks
Mike
