I found most of the bolts around the engine not as tight as they should be...back plate and cam gear cover. Was I supposed to use locktite after the CDI conversion or is that normal for a new engine? Even the saprk plug was not quite snug.

Additionally, after reading throught many other posts including Ivans who runs the same set up, 7700 RPM is actually the expected peak and I was flying at 7600...so right at the peak. I'm starting to think I was just too lean and maybe the lose bolts added some air.

I'll test it again tonight at a richer setting.

Thanks for the tips thus far.

Colin.
