  • Zenith carb adjustment
  • Hi everybody I've been out of commission for a while,short version had Quadruple bypass. I was finally able to get out and do some work with the naa today.It runs like crap,%99 sure it's the carb. I just recently reassembled the whole tractor after doing some major repairs and complete repaint. It has the Zenith carb, it has 3 adjustments and I can't find my instructions on it,and can't remember how. It has the T shaped adjustment on the bottom then the other adjustment on top.The engine starts real easy but has no power and runs rough when trying to increase rpms.can anyone tell me how to adjust this carb,it ran very well before I tore the tractor down? Thanks in advance,God Bless,Beth and Allen.

  • They adjust the same way the M/S carbs do.

    Idle mixture is clockwise to richen the mixture counter clockwise to lean it out

    T-handle is the opposite.
