It was crap through the rev range, I reckon I may have had a dodgy tank of petrol as it was ok before I filled her up,tried STP and put some Isopropyl in but no good,so as it was winter,thought I'd do the whole fuel system once the weather was better..Had to get one mixture screw removed professionally on number 1 carb the rest I replaced as a matter of course.I've been meaning to sort it for ages, now seemed a good time Can I just swap the LT leads into 1 and 4 coil, as the HT leads won't stretch to swap on plugs to see if that is the problem?Thanks
Gnasher I'm going to look well dumb here, but where is the bleed hole on the carb body ??
