Shifting Gears 101
Simple question:
When shifting from first to second, would one expect to get everything first has to offer before shifting to second?
Not talking about watching the rpms or gauges... but the feel of it.
The reason I ask is that I recently tuned up my 1977 four speed... and I notice that within a few seconds of laying on the pedal in first gear I am getting all that it has to offer before going to second.
I wanted to make sure this is a good thing... just to make sure I am not "all in" too soon.

this sounds more like a timing question than a shifting question.
you say you are not looking for an rpm range, but this would be something that i think we need to know to help better. also speed.. if it only takes a few seconds, but your at 60mph in 1st, maybe it is a good thing. if your at 20mph, the motor is screaming, and you feel nothing is left, maybe you need a rear end swap... i guess my point here is that there are a lot of variables, and we need a few of them to understand the problem more effectively

Are you certain that the secondaries on the carb are opening? [Hint: You have to have someone depress the accelerator to the floor (engine OFF, of course) while you are manually holding the secondary air valve open; then see if lower throttle plates are totally vertical.] Also, you may want to verify that the choke 'secondary lock-out' gizmo is working like it's supposed to.
