I just read the thread and I like where 52Carl is asking about spark.
Coils are very notoriously unreliable and can puke without notice or visible signs. If you are without spark, I'd swap coil for one that you know works. If coil is deemed good, then I would replace the points. Had a new set of points puke recently and chased my tail for a bit trying to figure that one out! New plugs have been known to be crap too... brand can make a difference. Don't rule out plug wires either.... Condensor failure burns the points....are they burnt?
In short, I would not bother with fuel, supply or carb at this point... I'd chase spark. If you determine your spark is good beyond all doubt, then chase fuel.
These old girls are pretty simple.. compression, (timed) spark and fuel is all you need as I know you know... good luck with it, keep us posted on your solution when you find it.
