    hi,
    I bought one of Justmowit's old 2 cycle Toro's, which quickly became my favorite 21'er. compared to my other three toro commercials it's a hot rod. They obviously made some perfomance modifications. The RPM's are way higher than my others and I am able to cut faster.

    Can somebody please explain how I can get a little more RPM's from my other 2 cycle toro's. With the air cleaner off I see there is some sort of governing spring which affects RPM, one end has 3 choices of holes on a lever, not sure what that would do. Is there a screw on the carb for adjusting too? I am wanting only 200 or 300 more RPM than the factory setting.
    thanks :waving:

    I use a small drill bit and make new holes, then check with a tack. 3600 will keep you in OSHA specs for 21 inch tip speed.

    3600 rpm on the Suzukis puts you far above OSHA specs for Tip Speed...The Units Come Stock @ 3400 rpm & 1850 fpm....I have the Dealer set Them @ 3650...He Removes the AF Cover and Fiddles for a Few Seconds and it's Done.
