Spark Plugs & AFR changes

interesting. since fuel and air volume are close enough to the same, does that mean a richer AFR = more complete combustion, or is it the other way around?

ive noticed differences too, i'm currently playing with a 12A PP with a 48IDA, and i've tried a few different plugs in the "tuning the carb" phase.

in the idle/low speed range the rx8 plugs actually wanted more fuel than the autolites.

the W/b on a p port is kind of a slippery slope, its on there...
