"Porting" a Stihl 021

[Saw Dr.]

Did you round out that exh port floor before you put it together?

Yes Sir I did.

Just put a tank and a half through it and am really happy with how she runs. I dropped a large Red oak and limbed and bucked everything up to about 14" with the 021. Before tearing it down it was pretty anemic on power. As I said in my prior post I have to lever on it pretty good to bog it down now.

The old girl is not a muscle saw but has some heart now:msp_thumbup:

If you look back far enough I stroked an 021.... worked well...for what it was

Yes but it didn't stay together. I have it in my shop in a box. The piston was cut too thin on the top and it came apart and destroyed everything. If the chamber would have been cut and more metal left on top of the piston, it may have worked out better.
