    What type of engine is it? Are you saying it idles when it's cold or not at all?

    if it is an HT motor AND you have the idle screw all the way in without getting a good idle speed, then drop the needle down to a more lean position

    does it matter? i always kill mine at intersections, personally.

    sounds too rich. looked at carb jetting yet?

    quick test. wind screw in all the way. turn fuel off. wait. wait a bit more. dont touch throttle!

    once it runs dry, if it really revs out, and does so for a few seconds...rich.

    if it revs up and dies in less than 2 seconds...just about spot on.

    if it coughs and dies instantly...lean

    Have you tried adjusting the idle screw yet? I didn't even know it was possible for these engines to idle until I found this forum!
