Well if it didn't stumble its probably ballpark. How close depends on how much load and whether you were able to test it up to the point the primaries take over. But yes then if stumbling on a normal accel from stop light to 30 mph you want to try a more initial pump shot.
Wires for testing. For short term, anything that is handy will work. I've used electric wire strands as well as music wire. Obviously stiffer wires are a little harder to shape. Shape it so one end is in the air bleed, run it over the choke tower if there is one, then under the air horn. I like to make mine so both bleeds are on one wire. Either way, trap the wire under the air cleaner gasket and air horn.
.023 might be fine to start with. See what happens, then try two or smaller based on the results. You will probably have to readjust the idle mix screws.
At some point, its helpful to map out all the bleeds and restrictions on the carb.
How big are the air bleeds?
.023/2 = radius. radius squared x PI will equal area.
Do the same calc for the idle air bleed. It's probably around .070"
Now when you stick the .023 wires in there you'll know about how much change in area occured. You can then figure the equivalent air bleed size. Neat huh!
With the carb mapped out, you can then do some better comparison with other peoples experiences on racingfuelsystems forum. There's a limited range where these restrictions operate predictably. For why, go over to Racing Fuel Systems forum andlook at the threads on Emulsion Tuning for "two-phase flow" and the one on submerged idle restriction.
