I bought a 4 barrel 600cfm carb off of Ebay awhile back. I gave it a rebuild kit (I've rebuilt a few without any problems) but this one is acting funny. The truck fires up right away, but instead of going down to idle, it keeps reving up! After revving really high the motor dies. I have a few theories.
1. The floats need to be adjusted
2. The secondaries are stuck open on the carb gasket
3. I really screwed up the idle adjustment screw
Anyone have any experience with this?
