    Echo CS355T just purchased and have run 1.5 tank of fuel. After saw gets hot and sits it is very hard to start. From reading on here appears they are sent with the carb tuned very lean.

    Can anyone explain how to richen up the carb. Do I adjust the L or the H setting. Turn the screw clockwise or counter clockwise?

    Thanks

    Have been using a old Stihl 026 for years. I like the size of the Echo.

    Thank you. I did read that it explains adjusting the L but does not describe the H. I assume need a tach and adjust H around 12,500rpm.

    I know that is Echo recommendations but what about from the guys that have tuned these saws.

    The H is adjusted full ccw, so it doesn't run lean. If the limiter tabs are removed the carb is adjusted from lightly seated to
    Idle adjust screw initial setting turns in** 1 3/8
    L mixture needle initial setting turns out 2 5/8
    H mixture needle initial setting turns out 2 5/8
