Paul, I don't get a lot of the early stuff in the shop to rebuild, like the H series, or earlier carbs, so I don't claim to have a lot of experience with them. I do mostly the later HS series carbs for the MGBs, Midgets, etc., I would recommend Joe Curto for your early series carb rebuilding. Not that I don't appreciate your desire to let me rebuild those carbs for you, I do, and thank you, but I would feel more comfortable having you send them to someone with more experience in those carbs than me.
