The PZ22 carburettor will need the float height set when it is installed with this manifold. In the past we have used the following settings with a flat engine mount and had good results, It may not be 100% right in your application but might be a good starting point due to the carb mounting flat.
Float height 22mm 23mm,23.5mm,24mm
Float drop 24mm
mixture screw 1.5 turns out.
this kit can be upgraded with a methanol jet kit if needed
