Joe Flanagan, I think you might be on to something with the "extra spring" thing. I didn't know what it was, and I threw it away. As soon as I have the time I'll go get another set of points so I can install the extra spring. I'll just keep the new set of points for next time and reuse the spring then. I had never seen an extra spring with a set of points before...strange. The more I think about it, the more sure I am that the points floating at high rpm, due to the weak spring has got to be the culprit. I'll let y'all know how it turns out, when I get the time to try it.
