update found problem
after spending a very long day (about 10 hours), with two engines I swapped parts until I narrowed it down. Change each component one by one (plugs, plug wires/coil, cdi, pulser coil, charg coil, fly wheel, everything.) And still had an intermittent spark that at one point stopped sparking at all.
What I found to be the problem was a small harness between the CDI harness and the Pulser Coil Harnes. It had one wire in the connector that was coming out as it was connected. A little super glue and problem solved.
However, I don't see that harness in the parts section. It's about 6 inches long, about 7 wires going in/out, with one wire going to a ground.
The connection from the CDI to the Pulser connect, is there any problem running the engine without the middle harness peace?
