ouch that hurts to look at....why i pull the muffler on every saw i buy before i do anything....i seriously doubt you did that in the short time you had it.... think im going to pop my muffler off and take another peek it was perfect when i bought it.... thats on the exhaust side mostly right? so it would not be from ingesting fines? Man thats a ruff looking piston.....the 3.7 i have that i said is lightly scored looks mint compared to that.....Sorry to see that.... great pics and write up... thanks for all you do.....

Andre aka andyshine has a good video for removing the limiter caps. The guy I got it from had no clue how to do it. This shows how easy. I didnt remove the carb to do it myself. I just removed the rubber piece that goes in for keeping dust out at the carb tuning area.




I just did the deflector like his in top video.....

SN not following what your saying.   You pulled the defector apart?  What did you do to the muffler itself?

I left the muffler be as i read a few people said all they did was the deflector... and i felt it ran decent with just adjust the carb ... so i removed the internal baffle on the deflector and left everything else stock at least till i run it awhile....now on my cs 490 i did the deflector and removed the tube.....the timber wolf was good enough stock so i did a very modest mod on it....and tuned it pretty rich and run 40-1 redarmor in it.....if i feel the need i will cut out more in the future ....some people said they did nothing but retune  them ...I like to go a step at a time ....I still have not done a mod on my cs 271t just retuned the carb and its running pretty good mind you it see's palm frongs most of the time....it filters better and clears the fibers out from tyhe clutch area better then the cs 2511....

Want to say Thanks to Nate at POE. That was super fast. P arrived today and installed.

Just fired it off. Learned alot about the 590 while in there and I like the build. Only thing I didnt do was split the crankcases yet on these to see whats in there bearing etc wise.

Echo 590 600 620 oiler issues.

Few folks keep complaining about the oilers in the 590 etc in the chainsaw repair group not lasting even after buying new and replacing.

Just read this =  Echo had an issue with the oil pump on the 590 600 620.
They had a spring in the oil pump that would catch the gear and lock the oil pump up. The oil pump has been revised updated with an improved part.
This happened to several CS590 saws and the issue was corrected with a washer on the new pumps.
