what would cause a starter not to recoil all the way back in.i been having problems with a starter i bought off eBay.the damm thing dosen't want to recoil back in all the way and it's hitting the fylwheel which is grinding the sh*t out of the starter.i shimmed the starter both ways.you can shimm it down and you can also shim the block plate to bing it back from the fly wheel.low and behold the damm thing still hit.
