Radio Shack part # 6403022 seems to be what has been used, 100 pack of "steel flat washers, +20 each: #2, #4, #6, #8, #10." I had trouble finding it in the store, but they had a bunch of random variety packs laying on top of the pull out drawers full of all of the electrical components.

Apparently this is a commonly used washer pack for a wide variety of motorcycles, as after doing a google search for that part number, the first results page had several other makes of motorcycle forums referencing those radio shack $2.49 100-pack for carb mods after pods...looks like 64-3022 is/was an alternate part number for the same thing. #2x.020 thick washers, or m3 x .5mm thick (same thing).

RS: who'da thunk it?

The .020" thick #4 radio shack washers were thicker than I'd care for in fitting to the non-spring-loaded-needle vm26 slides. Around .010" would slip under there, but much thicker and the needle won't be free floating as it should,& will probably wear a lot as it may rub the needle jet a lot. The #4 washers were .020" or .5mm, and the #2 washers are .4mm thick, but would need drilled out, as they don't quite fit around the needles
