Yesterday I rewelded the deflector back on, picked up another load of wood in Breckenridge, and got home late. I ground on the weld a bit, and installed the muffler. By then, it was about 11 pm, so sleepie-sleepie time. I stopped at the Stihl dealer before work, and talked to the tech. I like. Asked him to verify that I had the carb. adjusted correctly( honestly, I hadn't touched it.) he was 2 weeks backlogged, BUT this was his first customer modification of this sort, so he was intrigued. 45 minutes later, he calls and says it runs very well. OK, see him after work, he adjusted the carb., and threw in a new NGK plug. We cut some cookies out of some 10" pine in the back, and I noticed the difference. That's with the crap, ground-down safety chain. Home now, and cut some of the green Pine I have out front. The saw does not bog down as esily as it did before, keeps the RPM's up there better. The increase is not dramatic, but definitly noticeable. Increase in noise in minimal. So I'm pleased. I'm gonna go swap the crap chain for the new RS chain he made, and see what's what. I'll check in later. My sincere thanks to everyone who lent their input on this. JB
