750 F2 carb problem?

more likely a dodgy float valve, you cant always free them with a tap with a spanner.

I had to strip and rebuild mine and three of the float valves were stuck and needing replacing.

An update on the F2 carb front: a motorcycle tech I know who has been in the game since the late 70's spotted me fettling in the garage as he was passing by and reckoned with the right tools the no 1 floatbowl should come off without taking off the carbs - he was right. I took the bowl off, dropped the float out and the needle valve and gave everything a good checkover and clean and reintsalled - still the petrol peed out! Looks like the carbs will have to come off after all but I sent off for a new float valve from that nice Mr Silver to be on the safe side.

The good lady is away visiting family so before dismantling the carbs I dropped the float bowl again to try the new float valve - straight away comparing the old and new one it was obvious that the operation of the old one was nowhere near as good. Install the new float valve and bingo no more gushing petrol. it fired up easily and a quick ride showed everything back to normal! Time for a celebratory beer.
