add one more thing to the learning to tune issue. have a helper run the saw while you tune it. stand back 20 feet to listen inbetween tweaking the carb. i have a hard time hearing it while running some saws but if i stand back to listen it is clear as day. even the ones that are easy to hear when running them yourself become more noticeable with a little distance added.
201T....cant hear them if my life depended on it when i am the one running one...If i stand back 20 feet or so i can hear it. there are a couple other ones that i get help to tune when they come in the shop but i am drawing a blank on which sawsNow that is interesting, I might try that. I suck at hearing the burble clearly on most saws, so I chicken out and leave them too rich.
