The Cub Manual Site seems to be down right now, I was going to take a look now that I've had some sleep... Your numbers look pretty normal to me.

The trouble is, a coil cannot be 100% tested for operation with an Ohmmeter. A shorted turn or two will not change the Ohms reading much at all, but will use up the energy needed for a HOT spark as HEAT inside the coil.

Besides the possibility of a bad coil, is your "impulse" working properly, and have you checked the "timing" of the cam to the armature? (It's in the manual).

Since this post is now a couple of pages "back", if I can be of any more help, start a new thread, or email me.
