Prepping for crc- I only have 110' track for testing- My Putnam motor is set at 18 on the endbell, it has 12.4 12.6 12.4 on the can and 1568/1572 on the rotor. On my track I am rolling around a 4.10 most days. What changes should I be looking at for this race? same timing more gear? more timing? less rotor/more timing?

thanks
