I have a craftsman 14 / Poulan 2000 I recently purchased.
I'm going to do a muffler mod and re-tune. Ran it last night and it starts and runs well.
It seems like it revs lower than my other saws, which got me thinking about how I could raise the RPM to make it a little zippier.
Since HP is torque x RPM, I was thinking if I could mod the engine to raise the torque curve higher and raise the RPM it would make more hp overall.
I've read here you can increase torque by compression, and you can raise rpm by raising the exhaust port. The compression part I understand but not sure what port mods do.
Do you experienced guys have any other suggestions for improving RPM (both in cut and max) and usable HP?
