Since WCFB carbs were mentioned. I have a couple of Original Carter "Strip Kits" unopened and think they are for these carbs. Part number on kits is 10-101.
they have 12 little numbered bottles but cant see whats in them, thinking jets. 2 bottles with 2 in each needle and seats, and 4 bottles with 2 metering rods in each of them. Not sure if any one could use them, but if some one wants or needs them make me an offer. No no no thats too low....hahha
