Carburetor vacuum piston for Honda's 360 twins. Sold individually, this is for one carburetor. This diaphragm is made from Viton rubber which is the best rubber to use for carburetor parts. Old diaphragms degrade over time and when they tear or begin to fall apart the carbs can't work properly. Don't use any carb cleaner or compressed air on the carbs with the diaphragms installed because the diaphragms can be damaged.

NOTE: Be sure to line up the rubber tab on the diaphragm so the slide is in it's proper orientation.

We also carry just the diaphragm here.
