I can't believe you have two bad coils. Are the points and condensers BRP or aftermarket?? I suspect your digital meter is making you chase your tail... it is difficult to get a good connection on the secondary high tension lead (AKA the spring connector inside the spark plug boot. Have you tried an Ohm's test from the green wire on the primary winding to the secondary post of the coil? Put the coils back in, use the locating ring when installing. Try using a .020 feeler gauge to set each point assembly. Watch the cam as you rotate the crankshaft... when it opens to the widest point, stop and set the points. Reading a feeler gauge correctly comes with experience, but the .020 feeler should slide through the open points with a SLIGHT drag, but not cause the points to open, even another .001 . Take your time. Make sure the screw with the wavy washer underneath it is snugged down after setting the points. Now do the other side. Last, go back and recheck each set again... .020 feeler gauge with a slight drag is correct. If done correctly, that motor will purr like a kitten. The feeler gauge method is a simple time tested method. To check spark, set the flywheel back on and finger tighten the flywheel nut.. no need to torque at this point, just to check for spark. Good luck on your motor! Hang in there.
Forgot to mention, I didn't see what you have been using for a spark tester? You need an open air gap tester with a 1/4 inch air gap. Neon light testers are inaccurate and will not work. An old spark plug, with the gap opened up will work in a pinch.
