I came across a Zenith Carb that has the letter "G" just above Zenith. It also has an adjustment on the main jet in place of the plug. Anyone know anything about this carburator?

The "G" is just a casting mark. The needle adjustment on the main jet is an aftermarket item sold to save gas by leaning the mixture. If the jets are of the correct size and the carb is set up correctly otherwise no additional leaning is necessary. The mixture should be able to be leaned enough by closing the choke rod adjustment.
