Like you say,,check your float height, needles and tubes,, clean,check jets etc, air mixture screws and sync the carbs...also check needle diaphragms for splits etc..

I may have missed something off...

Hope that helps.

Carbs stripped back and i noticed on two of the four tube holders were missing the o ring seal.not sealing then ...replaced the said o rings.everything else looks ok so im gonna assume that this was my problem....then again assumption is the mother of all cock ups int it ?.didnt have time to test but will post results when i do
