I broke one of the discharge nozzles on the Holley 4000 trying to get them out for a rebuild. Mike's carburetor parts did not have them. I did find instructions that said it was easy to break them when removing them, but they did not suggest where to get replacements. I hope someone knows where to get replacements.

Are you talking about the brass tubes (1/8”) from which the accelerator pump fuel shoots out of or the main circuit fuel discharge nozzles (1/4”) ?
