run the right hand vac nipple to the fuel pressure regulator direct and bin the airbox pipe completly. the fact nothing is on there would explain the poor running! the left most nipple and the one round the back should both be blanked off.

check the idle switch clicks when the throttle is closed, and the wires to it haven't snapped. the idle switch is underneath the tb.
check for vacleaks too, especially look at the rubber bung in the rocker cover for the breather valve. prone to splitting round the lip
