I have a few motobecane 50v's 1977, and 1978.
the floats seem to be in different places on the needles of different carbs. some are closer to the tip, some are closer to the bottom.
1- Is there a proper height for the float to be on the needle?
2- are the carbs on pre78, and post78 mobys exactly the same aside from the air boxes, and intake manifolds?
3- Since the carb moves with the engine, is there a proper angle to mount the carb on post 1978 models? is facing the carb straight up when the moped is not moving correct?
