Hello, I know this isnt strictly "scooter" but I know there are some on this forum that know their stuff so I need some help. For some reason, petrol keeps pouring out of the overflow pipes on my carb. The carb was opened to find that the float level was too low so this was raised. Also, we cleaned the seat and the valve by the float (it doesnt look worn) but it is still overflowing? It's really strange as it should be at all, it really is filing the airbox up quite quickly, the carb is a 28mm mikuni standard to the bike, cheers
