Thank you very much!
120-130 is low ish.
This would get them up to 145-150 range.

Are the LRB kits for Poulan any better than the ones they make for the McCulloch? You can't use the wrist pin with the piston supplied with the piston as it is too small for the connecting rod and will just fall out. Seems to be O.K. if you reuse the original wrist pin for a good press fit in the rod.

I doubt the piston has been chrome plated as the original LIL red barn ones weren't. Running a bare piston in a 3400 with a bare bore will end very badly in about 30 seconds.
Mark, Kevin Simpson (I think it was him) had a LIL red barn piston break in an SP81.
