I have a question. I have a 84 camaro z/28 with a 305, and i had to put on a new carb recentely. I need to tune the carb a little to get the best fuel economy and best performance mix, due to the damn gas prices. And i was wondering if anybody knew which side was the fuel, and which side is the air. There are two screws on teh front of the carb. I would greatly appricate it.

2 screws on front are for idle mixture, run em in and back em out 1 1/2 to 2 turns Heres some resources.... ......http://www.buickpartsdirectory.com/c.../articles.html

The gas goes in that little steel line at the front and the air goes in the top.......................an 84 probably doesn't have mixture screws, preset at factory.

Its a rebuilt carb, do you think when they rebuilt it, that they left them little plastic things out?
