13...OK. 17...VERY BAD!goingballistic said:Good catch I was wondering if anyone was awake! (The) numbers escape me but I think it was somehwere in the 13-17 range, don't remember now.

14.7 is the scientific best stoichiometric rating for complete combustion. However, running a bit richer (low 14's) is preferred for our engines if I recall correctly.
