You do not have to remove bowl. You can loosen the big brass screw on the top of the bowl. Then turn the nut to remove the needle assembly.

Clean the needle/seat with some brake clean. Remove the sight plug and let the excess gas drain out into cup. Reinstall needle seat, making sure the gasket is OK. Look in the sight glass hole and adjust the nut so the parting line of the float is midway in the sight glass hole. Reinstall plug. Tighen big screw on top.

Start car and let it run for 30 seconds. Turn engine off. Remove sight glass plug and adjust nut slowly, 1/4 turn at a time. If gas is flowing out of hole, let it drain out. Reinstall plug and restart.

Recheck level and adjust. Remember that the gas level in the secondary bowl will NOT drop by itself when you adjust the float level down wards. Therefore, you must let the excessive gas flow out of the sight hole.
