['68OrangeSunshine]

Back in the day I bought a Sears Volts/Dwell/Tach tester. I've gone HEI and don't use dwell but I can still use the tach. Look for something like that. You might also pick up a Vacuum Meter at the auto parts store. Use it to dial in your Idle/Mixture screws. Highest reading is best. [17'' Hg @ 700 RPM for example].
Tips on cheating the ADEQ test:
1] One yellow bottle of Heet alcohol in a fresh tank of gas. Chevron is the best.
2] New PCV valve.
3] Paper air cleaner. Somehow the K&N just oozed extra hydrocarbons.
4] Gas cap. I keep a special gas cap in a plastic bag in the glove box in case I need it for testing my '68 Stepside or the '71 Jimmy. When the test is over it goes back in the bag.
5] Rainy Day. Since it's monsoon season, try to get there when it's raining.
6] Early morning. Don't try Mondays, though. The whole work-a-day world is trying to get thru on Monday morning.
7] Twelve pack of beer to entice somebody with real carb skills. You gotta find a buddy.

Good Luck
