my banshee was runnig really badly and seemed like it was miss firing on the right side and leaking gas from the overflow, so i stripped the float bowls off and cleaned the needle valve, when i put it back together it was just as bad spilling fuel everywhere, so i took both carbs to bits to change the assemblies over(right to left) now both sides are leaking, can anyone tell me if there is a float setting and how to set them up?
