I forgot to mention.  I do have a limit washer in there that I could 
remove that would probably get me to 2800 RPM redline.

I doubt one washer will change it that much, but you should definietly remove it.

I missed your reference to the mags.
It is a Slick mag, and using RHB32E plugs, which I'm pretty sure are 
massive.

That's what I was using.


  I never tried to start on it.  It just runs terrible though.

A fouled plug will do that.  I had that happen a lot.  Not with the fine wire, however.
