Hey Maurice,
When we were coming back from Ione, I wanted to ask you to keep an eye out to see if I generated any black smoke on a few of those suddend take-offs and stretches we did? As I said that day, I've been jetting up quite a bit and feel I've reached top upper limit, and I may go back down 1-2 sizes like it was before. The problem is these efficient ignition systems make it hard to get a good plug read. Its running richer (a little too fat) now and the plug insulator is still bone white. Let me know if you even saw a little black smoke to confirm my suspicions. That was a great drive.
