My stock carb is jacked! I've had it apart several times and cant get the float to stop sticking. I found several aftermarket carbs on ebay but they are all alot bigger and they have a different bolt pattern than the stock manifold. If I have a larger carburetor and manifold but only have the stock head would it function correctly? e.g. 19mm carb going into 14mm bore on the head.

 

just buy a big bore kit that comes with a carb!!!!!!! lol
