I came across this note by John Twist while looking for how to repair a
leaking vacuum advance unit on a Lucas Dizzy..
QUOTE:
OVERFLOWING CARBURETToR -- There is an unusual problem that will allow
the carb float bowls to overflow at speed. If the floats have the
metal fork, through which the axle pin passes, and if these metal tabs
are VERY worn, then the float can vibrate in a certain harmonic with
the engine and allow gasoline to pass into the float bowl, even if the
bowl is full. This results in overflowing and a distinct gasoline
smell in the cockpit.
