I've got Bing CV carbs taken from a '84 R65LS on my '71 R75/5. I've had an intermittent problem over the last couple of weeks where fuel will suddenly start spilling from either one of the carbs onto my shoe as I ride. If I remove the bowl, tickle the float a couple of times, and put the bowl back, all is well until a few days later when it happens again.
I believe that what is happening is that the float needle is rotating around from vibration. When that happens and the fuel level in the bowl is low (the float needle is therefore out a bit to allow fuel to flow into the bowl), the clip sometimes rotates into a position directly below the main jet housing. Then, when the fuel level rises, the clip hangs up on the bottom of the housing, which prevents the needle from moving into the fully closed position. Once I tap it a few times, it moves away until the next time it slips in there.
1) What does the clip really do? It seems to just hang out there loose on top of the float needle without contacting anything else (except the main jet housing).
2) Perhaps I installed the clips wrong when I cleaned the carbs a while back. Is there some particular way to install them so they don't get hung up on the main jet housing? The way it stands now, the clip is not centered over the float needle, but sticks out to one side. When that side faces the main jet housing, it gets hung up.
