Ok, so I was replacing distributor cap and rotor. When trying to remove old rotor, the single screw that holds it in, the dang screw head stripped out. So I borrowed a tap kit and attempted to drill it out. I pre-drilled a hole in the middle of the screw and then started working the tap bit in. As soon as I started to reverse it and pull it out, the tap bit broke off. Just the end broke off. The tap bit is harder than any bit I have, so I cant drill through it... Im almost resigned to leave the damn thing in there and just not change the rotor. No problems with the ignition. Any ideas on how to get the screw out?
