I have further adjusted the timing – it is now at 38 degrees all in at 2500 RPM, and at 19 degrees at idle, which is 1000 RPM. The motor sounds a lot smoother, much more relaxed at idle. Before, it sounded edgy when the timing was at 30 degrees at idle. Only one more work day to go before the next race on Friday! I still need to change the oil in the car, change the jetting (up 2 sizes), and clean up the new wiring.
