I believe you use a micrometer and measure the venturi of the carb--the narrowest part of the throat of the carb which should give you the carb size.

micrometer?????? use anything with millimeter graduations like even a ruler and base diameter opening, x2's came with a 28 or a 33, the 28 had an external pump and the 33 had a built in fuel pump, i think it was 91 when the 33mm came on the x2 and sx. could be wrong don't have any books in front of me right now.
