Uh-oh...flooding

And now the moment dozens of FABO members have been waiting for...the cause and solution:

When I de-topped the carb again and looked closely at the floats, it was apparent that the driver-side pontoon was against the rear wall of the carb when the fuel level was low.

The reason was that someone had bent the float "arms" to adjust them instead of bending the tab that rides against the inlet needle.

Once the floats were straight and the level adjusted properly everything seems back to normal.

These carbs have the nitrophyl floats btw.
