A compression test yielded low #s on 1 and 2 cylinders. I'll be pulling the head for testing by my machinist. This sucks, but the head is the only thing I didn't touch on the motor rebuild. It looks like a bad valve guide or stem seal, but time will tell. With the head out, I should be able to get a clear look at the cylider walls and check for scoring (broken ring indicator). Anyway, thanks for the concern. I'll post back when I get more info.

BTW, the timing was right on, and I did find two bad plug wires. So, it wasn't a total waste of time. Later...
