June 23, 200917 yr Hi Wayne, Have you tried this. Pulled the fuel pipe off from the tap. turn the fuel on then off. Dose the fuel stop if so the the valve is good. If not then the fuel will continue to flow into the carb and if on it's side stand it may weep out of the Carbs left side breather pipe. This shouldn't normally happen if the float is working normally. Paul.
June 23, 200917 yr Its the norm with every beta with a mikuni carb. There are many mods that can be done, there tricky but can cure this problem. Try using the search facility on the forum.
June 24, 200917 yr The problem is these tubes are meant to be atmospheric vents for the float bowl. Occasionally fuel will get splashed up into the tubes and because the ends of the tubes are below the fuel in the float bowl they act as siphons. If you cut a small hole in the tubes above the float bowl say about halfway up the carb body they won't act as siphons. An easy cheap fix. Can't beat free.
