Recently I've been having trouble with kickback caused by a misbehaving MSD ignition. Unfortunately I did not solve the problem before nicking the ring gear and damaging the starter drive on my Powermaster Hitachi style starter. Powermaster offers a factory refurbishment program. So I called their tech line and was told to send it back. That was last Friday. Yesterday, three business days later, I arrived home from work to find a package from Powermaster on my front porch. Sure enough, they had refurbished my damaged starter and returned it no fuss or drama even after I told them I messed it up. They really stand behind their products and I couldn't be happier with their service. if you're are in the market for an aftermarket starter give these guys a look.
