Tracy;

I'm happy you got this sorted out, but you still didn't answer the questions we posed...but now that ignition is (apparently) OK, how is WBO2 indicator indicating throughout operating range?

"Unburned fuel would show up as super rich wouldn't it?" ...I understand (and probably agree with) your thinking, but the question is: Would a normally rich mixture due to a "generous carb" result in the same hydrocarbons in the exhaust as when a misfire (non-ignition) occurs?, and what would the WBO2 indicate with that condition...Rich?...super Rich, out of Range? ...and you can answer and confirm this question for both of us by driving at some steady-state (Speed and Load), and monitoring the WBO2 indication...if in the linear region, and you pull the Choke (resulting in significant enrichment)...what does WBO2 indicator do?? I'd be interested in your observations.

Cheers
