Sorry you are still having trouble. At the start of this thread you wrote 'now been fitted with a SU, and after the rebuild started 'on the button' & ran OK for 60/70 miles.'

I would point the finger of suspicion at the carb. I had a terrible misfire on my MGB which turned out to be caused by a seal in the carb breaking up and starving the engine of fuel. It would run ok until put under load  when it would snap, crackle and pop all over the place.

If you have a spare carb, try it.
