carburetor setting SuperA

J.Reece · Apr 25, 2013

Can anyone refer me to carb settings for zenith carb on a superA. The main jet and the idle mixture settings. Thanks

The only way to change the main jet value is to change the jet 9non adjustable). The Idle Mixture is set to a combination of low Idle speed and best running. It is not set by the turns. Jim

Mine has a main jet adjusting screw which leans the mixture when turned clockwise.

Having one with that adjustment is not very common but I have seen it before. I would start at 2 turns out from bottom and then adjust it for max power and no black smoke

Even though it has an adjustable main jet , the jet size is most likely still calibrated for full load so you only lean it slightly but not enrich it beyond what factory determined to be correct for full load. Not saying that jet can't be replaced or drilled for a larger size. If you turn it out a few turns and tractor does not run rich with some black smoke it is no doubt a calibrated jet.
