12.8-13.5 is lean

13.4 on cruise isn't bad. Could maybe run a bit leaner, but, that's not a bad number.

If you can data log with the AFR, using RPM that would help a bunch.

Lol, Higher the number means FAT right....... haaaa ? I pulled a plug and it tells a different story. They look way rich......... Hmmmmm and when I stop on it it Puffs a bit and its stinky.

I don't have a data logger. The gauge has the output for one but.........

So what would be the Ultimate best case number on that Gauge?? I thought around 11.8 or so would be the target?
