Yup, bar is on it. I yank the pimp apart and have a look see tonight. Just wondering if there were any parts that wear out and cause the problem. The saw feels like a beast Tim. I put a new piston and rings on it with the jug with the broken top fin.  There was some scoring on that jug. I cleaned it up as good as I can. It's at 130 psi, with no base gasket.

The compression will go up some when the rings seat. What piston and rings did you use?

Learn something new every day. Compression will still go up from 155 after rings seat. You must have cleaned the cylinder up pretty well. Was the score below the exhaust port? If so that will not impact the saws performance.

The top cover for the 394 and the other bits will be at your place Monday.

Mostly below, but slight scuffing above.

Well great! You should be able to go play in your buddy's wood pile in short order. 394XPs are truly a beast, with no base gasket and a muffler mod (did you dual port the muff?) she will really sing!  ;)
