Your meter is set correctly. Short your meter leads together to make sure the meter swings to zero.
A good coil reading should swing the meter to the right to around the number 5.

.020 gap is good. I would definitely change that old capacitor. They may check decent now but are notorious for failing when they get warm.

A coil can read poorly or open and still give spark for a time. If the wire in the secondary is broken and the gap of that break is very close the spark can jump that gap and still fire the ugs. What eventually happens is the wire break gap gets bigger and the coil stops firing.
Where the coil heels attaches to the laminationsooks strange to me.
