Kind of what I was thinking. I pulled the plugs after I talked to you last and the only thing I can tell different is the pinch in one is way more than the other. Bearings in both feel great. Still un-easy though. I won't trust them untill they are identical. I guess I will run more fuel through them. At least the tight one any-way. I thought that "No break in" stuff was bull to start with. I want to know what mine are going to do before I take-off. Espeacially on a twin. I will drop a line to horizon. Thanks!
