Answer
Hi Bub,

I suspect one or more of the following:

The chassis grounds are not conducting well due to loose connections, corrosion, dirt/grime, or other defects.

It's possible the CDI is defective.

Spark plug wires/caps leaking current or otherwise defective.

If the problem persists afterwards, I recommend having a local tech inspect the problem for you.

Respectfully,
