Thanks Brian I will look today the carb (not old) has been empty all winter had one run before a strip for primary leak and then on next start up the float or needle stuck. Tank has always been clean and I empty it in the autumn and squirt some WD 40 in over winter. Stand by for photos I have a new float needle somewhere.vibrac: it would be interesting to know if you find any appreciable muck in the carb'. In conversation this week I was told that the floats 'stick' on their vertical guide pins after being left dry due to vibration causing notches on the pins which stop the float rising with the level of the fuel.
Anything is worth considering but have yet to pull mine apart to inspect. At the moment I'm always at the ready to give the float chamber a tap with the handle of a screwdriver.
Ok after breakfast I whipped off the Mikuni and opened up the float bowl, first problem is that you have to upend the carb to easily undo the 4 cross heads so there is no way you can leave the float & needle undisturbedThanks Brian I will look today the cartb (not old) has been empty all winter had one run before a strip for primary leak and then on next start up the float or needle stuck.

As an aside I have a pre monoblock carb on my KSS velo on its third float chamber and miriad float needles and reseating attempts it still floods at random times on tickeling I blame the so called petrol.
