Higher Oxygen %age in the exhaust gas
Hi! Techies, I own a 1997 carb zen.The mixture screw is turned for lean.Yesterday i went for pollution check,the guy there told me that my exhaust is showing higher O2 %age (2.93). He told that it should be near zero and he also told that it will damage my engine in long run.
Kindly give some expert comments.
P.S. My car is giving an average of 16kmpl in city and 21kmpl on highway.

And they are ever trying to reduce the emission to reduce pollution..!! Strange.., I thought CO2 or CO caused pollution. But Oxygen causing trouble is something unheard off.
Govt. must ask and encourage Maruti/Suzuki to revive the '97 carb Zen so that more O2 is pumped in the atmosphere resulting in cleaner air. What is a little harm to the engine. It is for national/global betterment..

Keep an eye on the temp gauge. As long as you are not operating under high loads you should not overheat.
Of course, pumping out O2 is not bad for teh environment, but your Nox might be high also due to the leaning.

If I saw more oxygen content I would say you are running lean and running to hot and have a more critical problem than a leaking exhaust.
Yours is a carb fuel delivery system so you wont have to worry about too many sensors etc, suggest you get your carb retuned to run slightly more richer to avoid running a lean AFR.
