She runs but misses a bit...
Here's what I've done so far and the results


New coils, all good
New plugs, all good, no change, checked with tester and good strong spark
Changed points and condensers for others, no change
New plugs, leads and caps, all good, no change
Cleaned carb and replaced kit, no change. ( it's the fixed main jet so I cant tell if it's the mixture, running on 50/1) Fuel getting into bowl.
Replaced carb for another just to compare, no change no difference.
Looked at and replaced flywheel, cam and woodruff key, something didn't look right......much better, still missing slightly but not as much
She revs well and idles down well but is still a bit lumpy
She's 99% there,it's the 1% that's starting to annoy me.....any ideas anyone.
 
Problem solved but needed to get worse before I found it, eventually running on the one cylinder......The black wire from the top of the coil was rubbing on inner flywheel, only just noticable and was shorting out. A 30 second job that took 3 weeks to find, so annoying.
