This is why I always wondered if we had Top mounted spark plugs, would we make more power, cause the flame front moves and hits the piston relatively flat, while in our motor it seems that the plug side of the piston would see the pressure first, than it would spread.......... but I liked reading that 12.6-13 was the optimum rich ratio, everyone on the other forum had been saying something in the 11's and that always seemed way too rich to me.....

If all of had access to a dyno, It would be time consuming, but rather easy to find the optimum advance for our specific setups.... In a perfect world I geuss
