Hello everyone, new here and first post.
I bought a saw, an Echo cs501 and set about investigating
the muffler, I took of the deflector and spark screen, behind it
I took out a short piece of pipe that was inserted to the muffler outlet.
I can look inside and see no cat or other obstructions.
In a bid to increase exhaust flow I am wondering has anyone removed this short tube
and what effect it had, and was a retune necessary.
I need advise as to whether I should go for more rpm or leave the saw at 11,400
Until it has some time on it, it’s new so I was afraid to run it lean.
Thanks for looking
