Quadrajet Conundrum

[Figuarus]

Guys,

I have a Quadrajet on my 283. This 283 has 1.92 Fuelie heads.

I have a stock cam.

I need to rejet this thing since it came from Los Angeles, and It's running WAY too rich.

The problem I'm running into is two-fold. First, While I CAN rebuild a carb, I know next to nothing about the Q jet. Second, I'm having trouble finding information on what size jet to use for my elevation.

I'm now at about 4500 feel elevation.

Has anyone done this before, or know of a chart to find the right size jets?

thanks again guys!
