We have a fuel mixture meter (wide band O2 sensor) set up on the exhaust so we can monitor the carb. The carb is a Weber 32/36 progressive. We're running at 12.5:1 most of the time, a bit leaner when the secondary opens up, which almost never happens. Should we be running richer than 12.5? From what we've read that seems to be the sweet spot. We are also looking into advancing the timing a bit (currently at 10 BTDC), but we want to avoid detonation.
