i have 2 of these saws, they are my absolute favorite 50cc saw and my go to saw to get stuff done. That being said, I have one that's got some hours on it and could use a good cleanup and new piston and rings. Do I send it out for porting? I also have a jonsered 2150 that's a basket case that I have considered sending out to have ported? Anybody have any recommendations? Am I wasting my time with my redmax?
