[ROVERNET - UK] Fuel Leak Update

I had a similar problem with the Solex carb on my P3 after it was rebuilt.
All the usual tests seemed to show no problems but the only way to get the
needle valve to seat was to give the thing a quick tap.  Eventually, after
comparing my carb with a similar one from another car, I found that the
gasket between the top and bottom halves of the float chamber was thiner on
my car.  I think the operating arm of the float chamber was pushing sideways
on the needle and preventing it from closing.  A thicker gasket was made and
it has never stuck since (4 years).
