Message	you stabbed the throttle: ~17:1. When running the engine in that condition around 2500RPM, the mixture will be pretty spot on around 14.7:1 just before going WOT. Given where the A/F is just prior to gunning it, I would say that their O2 setup was having an issue. [ ashspecz.com ] [ agpowers@bellsouth.net ] Enthusiasts soon understand each other. --W. Irving.
