If you have air box in place, what else can you tell us?
Is the choke on?
With a temp tank, I doubt you are at WOT so the mains are not in play. More likely, you are set too rich or lean at idle and opening the throttle kills it.
Did you adjust the valves?
What is the mixture set at?

Are you forgetting the fear of tuning carbs memo that was sent out?
Or, the one about carbs don't work without being smothered memo?
I'm just trying to find out what we're working with here. Then we can jet and tune accordingly.
Thank you for your indulgence,

You need the air box if you intend on doing anything more than an idle for an extended period of time.Cowboy Up or Quit. - Run Free Lou and Rest in Peace

Rule number one:
Vacuum carbs generally will not accept throttle in stock tuning without an airbox installed.
Rule number two:
Cleaning of the carbs requires complete disassembly, soaking the bodies and bowls in parts dip, rinsing, clearing passages with compressed air and or carb cleaning spray, new internal Orings installed, reassembly and bench sync. Failure to do so will result in ongoing problems and a lot of chasing your tail.
I would also suggest checking the slide diaphragms for pinholes and or rips/tears. Make note of your current jet sizes, and compare to stock listings to see if they've been screwed with by a previous owner. Without these proceedures beig performed, any suggestions here are educated guesses and may not necessarily help you.

Hi,
The airbox supplies a metered flow of air into the carbs. With the stock jetting the airbox supplies the proper fuel/air mixture ratio.
Without the airbox the carbs receive way too much air with the stock jetting. If you twist the throttle the engine will die because there is not enough fuel in the fuel/air mixture (too much air!).
Pretty much any modification to the intake or exhaust will require re-jetting of the carbs to compensate.
Thank you for your indulgence,
BassCliff
