    Hello all,
    I have a 14hp kawi engine on a Scag walkbehind. The engine manual from kawi says max speed is 3400rpm. Scag says set it to 3600. To adjust top speed manual says to loosen throttle 'plate' bolts and turn it to adjust. At maximum adjustment I can only get a little over 3400 rpm (no load). Does anyone know how to get that extra couple hundred revs?

    to adjust it, loosen the two bolts, and bump the entire plate back(i think thats the way...try it that way first) a tiny bit. Tighten, and check your revs. A tiny bump makes a huge difference. I have mine set at 3700 no load. Hope that helps
