I have a 90 Sportjet that I originally purchased with low #1 cylinder compression. The engine would crank when i bought it but ive never heard it running.
After rebuilding and installing the engine, I can't get it to fire. I have 12+ Volts throughout the starter system as tested by my multi meter. Engine turns over fine but I show no spark from any plug using an inline spark tester. Started looking over the ignition system testing in the Mercury manual but felt a little intimidated.
Wish this site was still up that "kenimPzoom" created, it must have helped a lot of people:

The stator on it is maroon colored but I can't remember the wire colors. I can look tomorrow. Haven't tested the cranking rpm's either to judge that.
Anyone have any other advice?
