Yeah for what Frank charges I don't know why he bothers. Do you suppose he loves us lunkheads and the hobby? My dad had two old Dooling .61s. one in a tether hydro and one in a beautiful Dooling tether car. He alway had spare rings. I'm going to get a couple extra for both of my ringed engines. Franks don't grow on trees.. In fact, due to word of mouth I may remove the ring on a new, never run engine and break it in with a Bowman ring. I'm buying my rings ungapped and go from there. My only problem is that I have a Mitutoyo dial vernier that measures my Craftsman feeler blades as being about .001" shy of what's etched on the blades. Do I trust Mitutoyo of Craftsman? Do I really care about .001" when my present end gap is .011"?[sm=spinnyeyes.gif] I'm going with Frank's recommendation. If he can make a ring he should be a good judge of what the end gap should be.
