Charley, I think you are misconstruing the "bedding in" part. That occurs
after the engine is started, when you run it at a constant RPM for a
certain period of time, say, at 2500 RPM for 30 minutes. The point is,
you want to get it running at this RPM ASAP, and not be cranking and
cranking trying to start the engine (as could happen with a first-time
startup with a new carburetor of a different type), and then fussing
getting it to run correctly. So I think it was sage advice not to swap
carburetors while the engine is being rebuilt with a new cam, even if the
long-term plan is to change to a Weber.
Twist's description of starting up a new engine is perfectly correct as
far as it goes, but it doesn't go so far as to describe the process of
bedding in a new cam.
Charley & Peggy Robinson had this to say:
