After more than 5 months, I finally have a test bed for these bearings and Wiseco piston from Dominant Saws. This beautiful 2171 has some pretty cool internals.
This saw lived it's previous life as a rescue saw from Cutters Edge. Unbeknown to me, the PTO side crank seal had badly wallowed out the case, and the crank was damaged as well. I put it back together with a new OEM case and a good used OEM crank. Squish was .037" so the cylinder base was cut .017", netting a final squish of .020". The exhaust port was de-carboned and polished. Otherwise, this saw is 100% stock. Initial compression after the first heat cycle was 152 PSI. After a little run time, and as time permits, I'll be going back in to fully mod this saw. After the first couple heat cycles, the piston looks great, as seen below.
