Robert,
I couldn't find my old ones in the garage......must have brushed them right off into the trash when I finally got my new ones. On a positive note, however, the cyclewareables site seems to be working again.
Upon finding this out, I also came across a "notice to all customers" which stated that the operator is apparently having some medical issues and is the reason that my order may have taken as long as it did. So, if you can be patient they will send you the parts. Of course, I feel like a prick now for ripping on them about it taking so long.......
As a sort of apology, here's a link to the page to order those washers-
http://www.cyclewareables.com/pages/carburetor_o_ring_kits/carburetor_o_ring_passage_plug.htmJust scroll down in the keihin section to "mixture screw washer" and order a pack of 4 for $4, but shipping isn't quite as cheap.
