fonzooorooo 10 Posted June 23, 2013 I know the legal limit's 0.2% (late car, so cat test), but what should I be aiming at when setting the mixture? Cheers. Quote Share this post Link to post Share on other sites
davidwort 0 Posted June 23, 2013 You shouldn't be aiming at anything, not by adjusting anything on the engine, it should look after itself, but a healthy 8v should be around 0.05, my last mot was 0.033 on a 1994 2e engine, I'd imagine the 1995 ady is similar.

Understood, and very useful. Thanks! Ours has clearly been messed with though - I had a pre-cat reading of over 5%! (post cat 1.6%) I've had a play this morning, and tweeked the air flow meter spring to give a pre-cat reading under 1% and post-cat between 0 and 0.1 (my meter's only got 1 decimal place) Seems to drive as well now as it did when de-catted and with the fuel cranked up(!) I was just hoping somebody with a manual could give me a manufacturer's spec and tolerance so I can et it spot on after the MOT's out of the way.
