Hello DP,

i hope you are well? And the passion for cars from Packard is still there?

Please allow me to return to our correspondence of fall 2020.

We have equipped the carburetor with these parts.
11B-126 nozzle passage plug
11B-159 bypass bleeder screw plug
75-538 metering rod

The idle jet has not been changed. it was standard. However, the engine is still much too lean at idle. It only runs at about 0.1% CO. The enrichment for power and rpm works. Do you have any idea which idle jet we should change to? Or could you even sell me something? I would be happy to hear from you!
Best regards Josef
