Actually i have done business with this man before .He also sells sum speed parts.This is however the first time he has ever done machine work for me.I have known him for over 10 years now and he is a stand up guy.He just made a mistake .I was a little discusted when i started this thread ,but he did agree to make it "right" .I even heard him tell the other machinest thta works for him when i was leaving "before we lap the new valves lets lay a straight edge across those tips to make sure they are dead on".I can always chack for coil bind with a feeler gauge before i button it up .I really dont think he would deliberatly try to ruin my motor to get even for me catching his mistake .I made it a point to not be Ugly with him when i brought them back ...
