Quadrajet issue

[Alan Roehrich]

Joe, if it came off a shelf at a parts house, I'd almost bet they've thrown away most or all of the Rochester metering parts, and they've used lead slugs to block the air bleeds in the main metering body.

I used to work for Mayo and Shrum in Nashville, we were the top carburetor shop in this area. It was company policy to refuse to work on remanufactured carburetors unless the work was on a per hour plus parts basis. I don't think I ever fooled with a remanufactured Q-Jet from any remanufacturer that had the original Rochester metering parts, or that did not have the air bleeds plugged. As a result, they all ran at about 8% CO on a 4 gas analyzer, otherwise known as pig rich.

You have to know what metering parts belong in the carburetor to fix it right, but if you have the gaskets, you can at least take it apart and knock the plugs out of the air bleeds in the main metering body, and that should at least make it somewhat useable.

If I can help, or answer any questions, send me an email or a PM, I'll do what I can.
