2 600s
I hit 12.6 at 4800 rpm. Ill tell you the plugs dont look lean. They look rich. I have always been concerned that the richness would wash the
oil off the cylinder walls. the dyno is WOT too. Which I never am if I want to live long. I wish I could dyno with a stedy throttle at around 2500 to 3500 RPM which is where it is at 75% of the time.
