Hi ppl, my old carb'd up cvh is giving me grief in that it often (esp noticeable when idling or trying to lol) misfires. With the bonnet up I can clearly see and hear the spark jump across from No3 lead to the head.

Ok now i've changed the spark plugs for a nice new set and gapped em up ok - same problem.

So I took off No2 lead and exchanged it for No3 thinking maybe duff lead but same prob, still on No3!

Any help???

It's doing my nut in grrrrr
