Hi guys!
New to the forum but not to Q-jets, Cliff and his excellent parts!
Now to my question;
Is there a spec? chart, covering all q-jet numbers, and what # jets, rods and hanger they had originally?
I have an Oldsmobile 7042251 unit at my bench, and I am trying to verify what was in there from the factory.

Help!!

Sincerely

 Welcome to CHP!

 Stock jet and rods for carb 7042251 was .069" Primary Jets, Primary Metering Rods 50B, Secondary Hanger K, and Secondary Metering Rods CH.

Thanx for the fast answer!!
Is these specs available on the net, or do You have some book?
Also, do You know what engines they were used on? This guy has a 350...? Maybe on 350 with manual trans?

 I actually have several manuals. Not one in particular. As for your second question, are you referring to carb number 7042251? Or another carb? 7042251 came off a '72 Olds 455cid manual trans. ;)

hansi:
Thanks again Ethan!
I wish these manuals were available on the net, but I am real happy there is guys like you around to provide valuable info!!
Some more questions;

The 251 is for 455 manual you say.
Do you have the carb numbers, and jet specs, for 350 man. and auto, and 455 auto too? 72 Olds..

Thanks

Hansi
