"If it ain't broke, don't fix it"
"If it ain't broke, fix it until it is"

Either of the above describes my situation. Rebuilt engine must, according to the cam supplier, be started up and immediately taken to 2500 RPM and held there several minutes. I foolishly started restoration on the working but dirty carbs (throttle shafts were very rattly)and I have the necessary parts and machine work in hand, and have read lots of tuning advice.

The question: with the jets centered and throttle shaft between the carbs connected, what should be the initial settings for the jets, the choke mechanism idle limit screws and the throttle butterfly limit screws, in order to start up and keep running? Not worried about running too rich for a few minutes; it's easy to change plugs and oil if necessary. Surely the factory must have faced this question several hundred thousand times, once for each car...Once I am running the rest of the tuning should be straightforward.

At least I didn't mess with the distributor, and don't plan to until later. It seemed to be OK when the car was running before The Great Teardown.

Any guidance, with occasional rude comments if appropriate, would be gratefully received!
