  • CArb rebuild questions.

    I have a 2000 SUV that I am rebuilding the carbs on. I have all three Mikuni kits. I have read about and plan to do the return line modification. My questions are about what the proper pop-off pressure is for the 1200 in a SUV. Also I have the 1.2 Needle seat size and would there be a benefit of going to the 1.5 since they have to be replaced anyway?

    lows: 1 1/4 (M.C) and 1 1/8 (p)
    highs 1/2 (M.P) and 7/8 (C)

      I have a 96 waveblaster2 that I rebuilt carbs drained fuel tank set pop off to 40 psi installed in jets idles great but when u grab full throttle 4 times its great after that it starts bogging or cutting out new spark plugs too if I cut it off and restart it does the same thing again grab full throttle 4 times in about 5 seconds it's fine then it starts bogging again u think it's a fuel problem or an electrical issue thanks for help Blake t.
