Re: aq271 pully on crankshaft
Is it just the pulley that's wobbling, or is it the pulley and the balancer?
If it's just the pulley, remove it from the engine, clean the mating surfaces of where the pulley and balancer meet, and apply a bit of paint to protect them (any color you like). If it goes away, good. If it doesn't, then the pulley may be bent.
If the balancer is wobbling too, it can be anything from a poorly installed balancer, a bad balancer, a bent crank snout, to loose thrust bearings for the crank.
