Just everyone know I got this back together. I'm still not 100% convinced that this was piston and/or piston ring related. I think its more related to carb issues also. The old rings still had to be compressed to the cylinder back. The old rings were half way compressed compared to the new ones.

Whats the carb preset adjustment for 026 pro. I ran it the other day and rpms were climbing and would shut off on idle. Today wont start but would flood itself. New spark plug.

I do believe that if you only had 50# of compression initially you definetly had a compression problem.  good chance that while the owner was trying to figure that out he mad multiple carb adjustments too.
You will love that saw when you get it running right.  My 026 does a great job!

rpms were climbing ...

Time for a vacuum / pressure check. I'll bet a dollar the flywheel side crank seal is leaking.  Known issue on these saws.

Yea its too long and big in round. The walbro carb cross reference guide has nothing for it in using k20-wat. Its lists K10-wat for the 026 and MS260. No listing for the 026pro in the guide. Thank you
