  • HP Carb Adjustments

    Well I've seen two possible settings for the mixture screws on the HP Carburetor for the G23LH engine. One says the lowspeed should be 1 1/2 turns out and the highspeed 3/4 turns out, and the other says lowspeed: 1 turn, and highspeed: 1 1/2 turns. I'm not sure which to run because both came from very reliable sources.

    My Go-Ped:
    G23LH w/ the following mods.
    ADA HP Carb Kit
    Timing Advance Key (10 degrees)
    .800 Spindle
    K&N Shielded Filter & Velocity Stack
    3rd Bearing Support

    P.S. Is there a lengthened throttle cable I can buy?

    low should be 1 1/4
    high should be 1 3/8

      Just set your carb to either of the settings and then fine tune it.
