View Full Version : Slightly OT: Carburetor Float question?

Anybody know the float setting for a Marvel Schubler updraft?
I have been told parallel to the bowl deck with the flaot valve shut.Any clues?

Turn the carb up side down. Make it paralell with just the weight or the float resting on the valve. If it has a drop setting, adjust it so the float doesn't touch the bottom of the bowl (right side up).

When I can't find a recommended float setting, I also turn the carb upside down and set it parallel. This seems logical and has worked every time so far.

http://www.juniorscomputer.com/massey/pg6.shtml has some specs as does http://members.aol.com/naa60512/carb.htm It seems to vary with model of carb.
