Engine Performance problem
1990 Chevy Silverado V8 Two Wheel Drive Automatic

I have a dune buggy, sandrail with a older chevy 350 and a holley 4 barrel carb. I do not know much about it, I just bought it and I have no idea what year it is and what model the carburetor is but it is fairly older.

The carburetor is a 4 barrel but it is only pumping fuel out of the front primary barrels. Theres no screw on the inside of the secondary barrels. If you know anything that could be wrong with the secondary barrels that could be not letting fuel come out, I would greatly appreciate it, Thank you!![img:5c32a7f1dd]http://www.2carpros.com/forum/automotive_pictures/469175_carb_1.jpg[/img:5c32a7f1dd]
