i think im going to try another pully first, and then try the shims. by what i can see, its not getting hung on the nubs.
the whole pulley is actually moving in an elliptical when the engine is running. in/out is fine, but its not true to the crank. the center of the pulley and the center of the crank snout sont seem to line up. so im wondering if my pulley ,may have gotten bent somehow. this crank pulley was given to me by my machinist, so it may have been in an accident or something. dont know.
i also bought a crank bolt, because my engine does not currently have one.
would it be OK to grind those nubs off, or would that throw things out of balance potentially?
