This may be a very simple problem, let me explain. I had a motor miss too like yours just after a tune up too! I metered everything & all is OK? Then I looked at the points again & found some oil on the contact areas. I thought top crankshaft seal but no! No oil coming from there. Next was my feeler gauges. They had a film of oil on them. Cleaned everything with acetone & re-gapped. It fixed the problem & may be yours. Check for oil spray around the top seal using a Q-tip to wipe it down too. Take the magneto apart, inspect & use a meter on each connection as you assemble to be sure. It may not "look" bad but the meter will show a resistance that may be hiding. DO NOT forget your capacitors using the ohmeter battery to look for the small charge made by the meter battery to discharge. An analog meter is better. If no help I would look again at a gasket missed in the carb or dirty jet or passageway.
How about your crankcase halves sealing area? See any bubbles as you turn it over by hand or excess oil around the sealing area?
Sorry, I missed page 2, some data here from me may not apply, sorry, 😳
I can add this. Be sure to use masking tape on the heels of the coils. Install the flywheel without the nut & roll over the flywheel a full turn. Next remove the flywheel & look for rub marks on the coil heels. Good way to check clearances. Remove tape.
Good luck!!
