Sorry for the confusion. I replaced the bearing in the first (bad) engine, and found the issue with the engine when I was putting it back together, so I took out the new bearing, put the old one back in, and sent it in for service/replacement. Now the Boca bearing is in a bag on a shelf, and stock bearing in the new OS.

Boca on the phone was pretty adamant about me using an open bearing in the rear, so fuel could lube the bearing. I went against his advice and with the advice of a few other pilots. OS and Boca say to use a bearing that is at least open on one side for the rear bearing. The front is shielded (rubber).

Anyway, new engine is a freakin' animal, and yes, it starts on the first flip just about every time. A 1.20 two stroke starts THAT easily with a little chicken stick, you just can't beat that!
