I live at 5200 feet above sea level in Colorado. I migrated from 2 smokes and just bought a new '01 426, love it. Ride mostly between 6000ft and 12000ft. I can't seem to get a straight answer out of the local shops as to the proper carb settings and I'm fouling plugs starting at about 7000ft. I believe stock settings are for sea level, no positive. Any ideas would be appriciated.

I have a 2000 426 with an FMF Powercore 4^2. I know it is a different Piper but I am also in Denver and I run a 152 main, stock needle, stock pilot.
