I was referring to the emissions created in the -manufacture- of these newer "cleaner" cars, compared to the emissions produced by a 20 year old car in the intervening 20 years.

Remove the Emissions side of the triangle, allow it to go to the level of a Euro-spec PRV and the Power increases quite dramatically, and the economy, on my car at least, actually improved too. I also forgot to mention that much over 2% (set by the adjustment screw) and you get poor cold starting problems, unless you re-jig the CPR, but we went down that route and it didn't work well. BTW mixture isn't just set by the screw as you know, and as I said, I'm not tellin' exactly what we do :-) BTW try www.veggievan.org - I haven't read these sites for a while though.
