I had a continual problem with my SH2/22 for the last year. I went through several different floats, pivot pins, needle valves and lots of general dicking about. I managed to sort it in the short term but the problem always came back. I suspect that the original Dellorto floats swell a little in modern fuel containing ethanol. My salvation was getting one of the remade Scootopia floats. They are about half a millimeter smaller and hence do not foul on the float bowl. Since switching to one of these, I've had no recurrence of fuel pouring out of the overflow or the mystery poor starting that was probably caused by flooding. The best £4 I've spent on a Lambretta part.
