Coil differences...

I replaced the cap on my original coil that had a so so spark and now you can actually hear the snap of the spark.
The web site of Vance Smith in Michigan (USA) says to open a plug gap up to 3X the normal gap and if the spark jumps that gap all is well. My bike now has a spark that jumps about a .25 inch gap and I can actually hear the spark. I think I am good on the spark from the Motpoplat at this point!

That is great news! Good job.

I am still scratching my head on the issue I had with the spare coil that belongs to my buddy as to why I could get readings with the cap and coil individually but not together. The new cap solved the issue but still leaves me wondering. I am thinking there was a broken connection inside of the cap that reconnected with the cap removed from the wire and then disconnected when screwed into the wire.

FYI These are the caps I am using...

It sounds like the cap goes open circuit when you screw the lead in, could be the tension on the screw?

Don't know... For a $2 cap it is fixed.
