Okay.That will make the job easier.
'cut the ignition at the end of a run, shift to neutral, stop and read the plugs'
That takes care of 'acceleration'.Idle reading should be simple.
'Cruising'(will find out correct name of carburetor circuit) looks like a bit of a problem.
Any ideas?

Simply cruise at a steady 60 MPH or so on a level road for 5 miles or so, kill the ignition, shift into neutral, come to a stop and read the plugs. You do realize, of course, that to get the most accurate readings, you must install new plugs for each test!
A better idea: Use an air/fuel ratio meter with a wideband oxygen sensor. This way you can read the exact fuel mixture instantly under all conditions as you drive!
By the way, the carb circuits are: idle, main, power and acceleration. You can add choke (or cold start enrichment) if you want to.
