When I open my throttle the sweeper does not go all the way? |

Use the LM1 meter and adjust the sweeper (loosen that tiny screw) very slightly to set the AFR to 14 to 1 under load driving. Should be stable from idle to WOT otherwise you have some other problem.
Worked great on my bus with Ljet. See pic on other post. |

You probably want to run a little lower than 14 for better power, and a little cooler running.
