My carb may be running on the seriously rich side, so I was considering installing an oxygen sensor that could measure my air/fuel ratio at wide-open-throttle, throughout the rpm range (say, 2,500-6,000.)
I am pretty confused by all the choices, so I thought I'd ask on this forum if any of the folks here have a relatively accurate oxygen sensor operating in a blow-thru (carb) environment. I see them advertised anywhere from $150.00 up... Seems like there doesn't seem to be a whole lot of difference in what they do, beyond having a single sensor or dual sensors, at least for ("no computer") carbs.
What is available that's relatively affordable, but works accurately? Are there units that have built-in problems that I need to stay away from?
Please steer me in the right direction. I need something that works, but won't break my sad little piggy-bank.
Thanks for any advice...
