I don't still use acetylene enough to justify the rent.
For decades, I have used propane as the vacuum leak finding tool. Have a base set on the workbench with the torch firmly fixed in the base. Neck down the tip to a small (3/16 works well) neoprene hose of 10~12 feet (whatever one's shop requires), cut a 6 inch piece of 1/8 steel tubing and insert one end into the free end of the hose from the torch. Now one can really pinpoint a vacuum leak.
The "tag is required" is for newbies to the old vehicle hobby, that are used to driving newer vehicles which are virtually impossible to modify. We have found AT LEAST 75 percent of vehicles before1965 have had their carburetor replaced at least once. Our kits are custom, and include the proper orifice fuel valve, the correct length accelerator pump, main jets, idle mixture screws, the power (economizer) valve, etc. If the prospective customer has been around older vehicles for awhile, and is confident the carburetor in question is correct for the vehicle, and willing to accept the responsibility for this decision, we have no problems with selling the kit.
