My first question is, would you go through the the trouble of replacing the o-rings on the sleves if you have no reason to suspect they are bad? Do they deteriate (sp) with age, or are they best left alone? The sleves are in great shape with no scoring or top rim, if that makes any difference.
Danny,I have the Ensign K carb. The only thing I really need is a new manifold, but I'm waiting until the last moment to buy one. The mag is not original, it a wico xh, but someday I will try to put an original one back on. I spent last night cleaning and polishing the head and shining up the valves. I hope to have the head put back together tonight, then I will turn my attention to removing the pistons. What could have caused a heavy carbon buildup (1/8 inch think) on top of the pistons?
