fuel leak

I took my +2 for a short spin today and when I came back I noticed a few drops of petrol under the car. When I investigated I think it is coming from between the carbs ( weber) and manifold. The drips stopped after a few minutes. I dont think it is leaking when running.
I am sure I saw mention of this problem some time ago on this forum but I cant find the thread.
Any ideas?
Chris

Chris,
Do you have a mechanical fuel pump? If so, have a look at the bottom of the pump. There is a small drain hole there. Just reach under the carbs and feel the bottom of the pump. Smell petrol? Looks like you have a fuel leak in the rubber pump diaphram. If you have watch it! The pump may be leaking directly into the engine and diluting the oil. Recommend you fix it fast - and change the oil.
Electric pump? Is the pressure too high at the carbs?
Also check float levels carb/gaskets.
A starting point - I hope.
E-mail me if you need to discuss this further.
Regards,
Hamish.

I just checked the float levels and I think they were about 1.5mm to high.
Reset and short test drive and all seems to be well.
Only problem now is that it doesnt seem to want to rev smoothly between 3,500 and 5,000 ( it was doing this before). In neutral it revs up smoothly but not when driving.
Any ideas?
