Quadrajet Problem Solving > Diagnose a Quadrajet carburetor problem

Olds 403, Qjet might be too lean. Help me please.

Ok, the primary rods are 55P if that makes any sense. Im still learning. :)

Did the carb originally have the black anti slosh spacer in the front passenger side by the needle and seat area?

I could have sworn that it did, but when I popped the carb open it isnt there. I know I wouldnt have forgotten to put it back in as I keep a very clean workspace and would have noticed it sitting there when reassembling the carb.

My friend has a 403 with a 224-234 cam. He used .074 jets with .045 metering rods. The rods have .026 tips ( check this).
Car runs like a bat out of hell.

Cliff Ruggles:
We supply .074" main jets and our full tapered .044" primary rods for those carbs to folks setting them up for high performance use.....Cliff
