Today I received a tiny tach/hour meter to go on my new Stihl Fs94R trimmer to track my accrued hours with it over the coming years. It's an awesome lightweight 2 stroke trimmer by the way. I decided to try it out on my Echo Cs-510 saw before I installed it on the trimmer.
The saw was purchased new in 2003 and I've cut approx 10 cords of wood a year with it since then. When new I removed the muffler baffles, deflector shield and spark arrester screen. I readjusted the carb to where the saw sounded right to me while cutting wood. It's running a 20" bar with sharp Oregon 20LPX chain.
When I checked it at WOT it hit 15,240 RPM on the tach. When I cut some 15" seasoned pine it fluctuated between 9,600 and 8,400 RPM. The saw started to bog when I pushed down hard and showed 6,600 RPM.
I must say that this saw really does scream and the muffler mod really brought it to life but 15,000+ RPM seems too much. I hate to mess with the carb settings since it cranks and runs really well and has been 100% reliable over the past 12 years.
What do you guys think?
