Thanks everyone... Looks like a rebuild is step one. Just wanted to make sure I am starting off on the right foot and making sure the holley is worth staying with.

I hope to get to it within the next week.

If you haven't removed the carb yet, start the engine and get it warm. Shut it off and remove the float sight screw. There should be just a very small dribble of gas out of that port when you gently bump the side of the truck when the float level is correctly set. If it runs out, the float is too high. If nothing comes out it is too low. in either case, using a large screwdriver and I think a 5/8 wrench loosen the nut and turn the screw clockwise to lower the float or counterclockwise to raise it. Start the motor and repeat the process until the float is in the correct position. This is important on a holley because you will never get the carb to work properly if the float isn't right. Hope this helps!
