#2 Full tanks increase fuel pressure, a poor seal on the
carb float needle valve will leak and fill the bowl, which
then over-flows. The tanks have about 10-15% free space
even when full to allow parking on non-level surfaces before
the tank vents begin to drain.

| Not really. For me, the question is do I bother making the
trip to the

qualified engineer -

problem - says that

to see where the

is engineer only
| territory.
|
| Part 2 of the question is "why would full tanks cause
this - why wouldn't
| the excess get squeezed out the tank vents"?
