Starting spark frequency? (ignition issues...)

To test the coil tower, I used this tester at the 10 mm distance and it gave a good spark when it sparked. For the spark plug spark checks I used the Lisle inline spark tester. All of my spark tests have been done with the key (using either my son or my wife to help).

I'll rerun the AC tests in the morning. The meter I've been using is auto scaling and may not be sensitive enough for lower AC readings so I'll try a different one.

Thanks!!

If it is getting good spark at the coil tower there is no need to do anything else except for the high voltage side of the dist. itself . Frankly, the "big" items at that point are carbon tracked cap or rotor, rotor "punch through" which causes a ground through to the dist. shaft, or just a bad coil wire. It can take what "seems" a long time to come around on one spark plug. Bear in mind the crank must make TWO revolutions between each spark at one plug
