toro 2 cycle needs more rpm

7 yr old self propelled blade clutch 2 cycle starts/runs well, but since new the speed is slightly slower than 3,000 published spec. How can I increase it slightly for more vacuum/power?

Hello Mitchella!

Check the throttle cable and linkage to make sure it is reaching it's fastest setting possible. If so, you may be able to bend the linkage wire a tad to shorten/lengthen its' reach just enough to raise the rpm a bit.

Unfortunately the throttle is control is also the choke, so if I push it further to get more rpm, it goes to choke. I don't have a manual (yet) for this engine but maybe there is a governor or something to adjust?

Engine Speed Adjustment

Hello: mitchella

There should be an adjustable screw which moves the throttle plate. Watch the throttle plate movement as the throttle cable moves the plate.

When the cable moves this plate, look for the screw that stops the plates advancing movement and adjust the stop screw to allow the plate advance slightly further.

Be sure not to overly adjust it beyond the reccommended engines top running speed. An overly fast running engine will cause excessive engine wear and premature engine failure.
