Stihl MS661-C Part 2 Test Dropping a big ol' Ponderosa

[@JS-oy6nn]

I got fairly decent gains from muffler mod, base gasket delete, timing advance, with a re-tune. But then I sent it to my friend and he did all the machine work and porting and that makes these saws a real animal 🦔

Do you have to retune them after changing out the air filter and putting a dual port muffler on them if they are M tronic?

[@JS-oy6nn]

@@gregmenniges5963 yes, when I did my 661 I wanted to see how it ran before and after a retune. I could definitely tell the difference after I retuned it. It cut better, idled better, and over all sounded much healthier. Before the retune it was clearly too lean.
