Well, I raised the exhaust more than I usually do - actually hoping to bleed off some compression. I also removed one of the piston rings. So, though she has more static compression, she is actually a bit easier to start, and she is very eager to rev. But I only had her test fired before I did that comp test. So dunno how she runs yet. I'll put a new handle on tomorrow. The piston was a pretty tight fit, but I have seen tighter, so I am curious to see how long it lasts with one ring. The bore is chrome plated - and thick. A lot of work to grind on it. So even if the piston starts to cause problems, I think I can clean it up and replace it.
