For me adding an aftermarket carburetor I would follow the manufacturers instructions for setting the float level.

Look at this sticker, lower left. This is before they put plugs to prevent adjustment of mixture.

You cannot have a sense of humor on here. Some people actually ask for torque specs of the most mundane bolts. It is like they would loose points in NCRS judging if the correct torque is not used.
Others have no mechanical aptitude or common sense and will try doing what you suggest.

If we loose our sense of humor this site would be pretty boring sometimes. I appreciate the humor and frequently agree with it.

If someone really tried to adjust their engine while the manual transmission car is idling in gear. Maybe they should be driving a Honda and leave the old Corvettes to those with a bit of mechanical prowess. I thought it was a pretty funny joke...

When we discuss things with people seeking answers we take our job seriously. I separate humor from business carefully.

Sticker does not say anywhere to adjust the mixture with the engine in gear.

With the engine at operating temperature, choke open, air cleaner installed, air condition off, parking brake on
  1. Set mixture...
  2. Set ignition timing...
  3. Adjust each mixture screw...
  4. If necessary readjust speed screw to specified idle rpm
Edit: There is no mention about adjusting the floats on the sticker.

Well everyone knows you can't let the clutch up while adjusting the float level...

It clearly says Auto Trans in Drive, lower left
I NEVER stated anything about floats in DRIVE!

Also you have to check float level and adjust mixture screws in Drive, parking brake on, wheels chocked.
Seems like you did say to check the float level in Drive...

And that would be for step 4 adjust idle speed if necessary.
