Try tapping the side of the carb with a hammer or mallet. BUT GENTLY.

It's your float valve getting stuck. You will need to clean the carb out if it continues.

I've heard people use a SMALL SPANNER to tap the carb, as knackered said.

It's more than likely that the fuel inlet valve will never have been changed, so it could well be worn, but yes initially, as has been suggested, a gentle tapping of the float bowl, though I tend to recommend the blunt end of a medium weight screw driver.
