To get back to my original thread, I have finally fitted the AFR gauge to my car, and what a pleasure!!!! I was running hugely rich, and have had to take the verboten screw in by two full turns to make any form of difference.
The car is running much better now, but I have reached the end of the adjustment on my verboten screw and she is still running rich. At full bore acceleration thought the gears, the reading comes in at a shade over 13 before she comes onto the cam, the reading drops to about 12 when on the cam. From reading in previous threads, I am aiming to get to about 13.7 on the gauge, is this correct?
So how do I weaken the mixture further if I've run out of verboten screw? She starts easily and idles lumpily at about 1,000 rpm. I'm not entirely convinced that I am getting full power on the cam though.
Any thoughts?
