Well after 2 nights reading up on web about setting up webers, i put the vac advance onto the correct port(!) of the carb, not the manifold.
turned out idle screw til it no longer touched linkages then bk to barely touching.
used a mirror n small flat headed screw driver, i turned
outthe mixture screw to get best lean idle.
then i turned out til it nearly died- bout another 1 full turn, then bk in again to a sort of sweet spot.
MUCH MUCH MUCH better pulling away on 1/4 -1/2 throttle smooth and consistant to 3000 rpm, but if i floored it before 3k it spluttered n back fired thru carb.
when i got to 3k, floored it and FEK ME,RRRRRRRRRRROOOOOOOOOOOOOOOOOAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRR
wahoo i do believe its on the right road, albeit still off destination but WOW
cant wait to get on A13 on thursday
watch this space
