misfire on stag

[Frank]

good morning all.
I have a misfire problem on my 1977 auto stag with lumenition electronic ignition
when stationary and warming up on idle,increasing the revs to around 1200 it
starts popping and occasionally stalls.
I am looking at the ignition system at the coil and then connector on the electronic ignition
I notice that the high resistance wire is joined together with the starter wire connected to the
positive terminal on the coil.
Is this correct or should they be separately connected to the positive terminals on the coil
Would appreciate your advice/comments please
Regards
Frank

If it was OK and now its not then it is unlikely to be a problem with how it is wired up.

Before going any further I would have a quick look at the carburettor diaphragms, check both for splits or tears. That can give similar symptoms. Quick and easy to do!

Your wiring sounds correct.

Too little information for a stab at diagnosis. Does it only do it at standstill? What does it drive like at light throttle, then at greater throttle etc etc.
If it wont even pull away then it could be fuel or ignition. Check fuel delivery from the hose to the carbs. Check ignition with a timing gun as you rev up - is the timing steady increasing advance as you rev up? Try a new rotor arm. Check inside dizzy cap for damp, or bad surface/cracks etc. Are plug leads old?
