Yea tried the needle position when all was standard but the leaner I put it the worse it ran the richer the better but still didn't cure the hesitation. Thanks for the help.

Ah - thanks, now it starts to make sense. Been fiddling with it this afternoon and it seems to run great with a 260 main jet and 30 pilot jet - the only thing I wanted to achieve is reliabilty, making sure it not runs to lean, not to maximize performance..

Respect!

thanks callum the carbs all working fine now but cant seem to get the powervalve set right now...
