    Extend the intake tract if you want more low end power.
    Put a high performance ignition system on it.
    Put a good carburetor on it.

    I got the high performance ignition and a h/p carb. So next is a longer intake?

    What small engines lack the most is umph, which the longer intake tract takes care of.

    Add a shift kit if you haven't already. it will help you keep that engine on the pipe.
