If you've got fuel at the carb inlet, but not in the float chamber, it can only be 2 things - Blocked filter within the inlet nozzle, or the needle valve has stuck shut for some reason (could be cr8p occluding the valve itself, or a problem with the float setup keeping the valve closed).

I'd go for the needle valve being at fault...

yeah the fuel wasnt getting through from the float chamber so i just swapped it with a spare bottom end of the carb and hey presto....got to strip the old one down and have a looksy its obv blocked up somewhere along the lines
