One thing a Commandoneer needs, ugh, among many other spares, is a hand full of fresh spark plugs and knowledge that they come bad right out the box, which I never ever in my life experienced but on Nortons, though I suspect its Brit Iron wide phenomena.
If not carb and not Pazion ignition then the fun begins to hunt for other things in combos till ya prove your manhood to be worthy of a road going Commando. Times like yours I so wished to be a baby and pay someone to take care of me, but alas not enough money nor experts around so stiff upper lip and begin complete inspection and dissections of everything you know can't be wrong. A voltmeter would help to see if gaps in the voltage along with the misfires or stalling. I have fixed or found some things by juvinile swift smacks and hard kicks, much to my peace of mind but lingering poor self image, eased by working lights and smooth running riding.
