Brought home a super a in relativly fair condition today and am still trying to identify it( no ser. # tag) I think its a 48 but will have to wait for daylight. Sat up for five years with no carb on it but I do have the carter carb. Evrything is free and turns. Are all the carbs interchangable? Have access to a zenith one. Will start draining fluids tommorow, any suggestions?
