Mike, under WOT, you should be around 28-32 degrees advance up to about 4800, then retard the advance(under WOT only) 4 degrees per 1000 rpm above 4800. I would also go from 10 up to 30 gradually on WOT from 1000 rpm up to 4800.

The retard advance over 4800 was a gift from Jake Raby to me. It works superbly, you don't need high advance way up there.....

Under light load, I'm up to about 36 degrees with light load at 3000 and up.

Otherwise your curve is nice. I have tweaked mine continuously for ten years and am on version 40......

Personally, I'd up compression to 9:1, at LEAST 8.5:1. Panchitos would be great on this motor, but it's not my money. I like JayCee no-leak pushrod tubes and white silicon seals.
