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.
