Hi Rusty,

He's using Tracy's controller.  I got the impression that it was idling
at 1000, but maybe not smoothly till around 1500.
Quote:
"Will idle below 1000 RPM.  Starts easily. Idles smoothly more or less
under 1500 RPM."

I don't remember the details on the muffler, but they are going to try
Jerry's muffler before getting off the dyno.  I'm really interested in
seeing the results from that as  I have one hanging on my engine.

Let's hope it sounds good Jerry :)
