I finally got around to going through my PP 655. I'm one of those that got lucky, and it turned out to be a Boost Port saw! This was going to be a quick disassembly, clean up, new rings, and new seals. Unfortunately, the divider that's epoxied in between the fuel and oil tanks was loose. So, I got to split the crank case. It's back together and running great.
The main reason that I wanted to go through this saw, was lower compression than I expected. As it turns out, the P&C are in excellent condition. I re-assembled it with new OEM rings. Compression is still only abouty 128 PSI. Oddly enough, it feels like 160-170 PSI. Squish is .032". There's nothing at all wrong with the saw, so that's just what it is. Anyone ever tested their PP655 BP?
Ah, I almost forgot. I was able to locate all the parts to set it up with the factory K&N filter. Everything but the base was readily available. CPR gave me the contact where he bought a base not too long ago. I called, and apparently got the last one. Had they had more, I would have bought them and passed them on to someone else here looking for one. It makes for a pretty cool looking saw!
