Thanks for all the input. I'm not sure why they only went to 5800. I think they might have been taking it easy on the new engine. This dyno was mainly for set-up - it had just been fired up.

Timing is set to 12 degrees. Saturday I tried something different, just closed all the idle screws, opened to 3.5 turns as suggested in the book, and then opened by quarter turns until it idled smoothly. This turned out to be 4.25 turns. Did not even check for balance. Seemed good at first, but temperature slowly climbed to red, and engine started running worse with some spitting. This is only about 10 miles. Took home and parked for now. I have an LM-2 on order and once I get this set up will try again. Maybe this will lead to enlightenment.

I am assuming or hoping the overheating is tune related, because I don't know what else to do mechanically to improve cooling.
