    What size tire are you using. Many times people put on a bigger tire just to loose power. Check tomming and replace the O2 sensor to start with. Also look for vacuum leeks. But the tire is a BIG factor.

    check the accelerator pump to see if its working - it should shoot out a shot of fuel into the secondary when the throttle is rotated fully.

    How do I check? The vaccume line that was going to it has no vaccumr so I put a constant one off of somewhere on the carb and the secinday opens and works jus feels likes its overloading with fuel at high rpms

    x2 on that the pump is actuated with an arm mechanically linked to the secondary on the carb.
