Jim (JR) Bullock - a 50+ year veteran building/restoring Model A carbs has opened a new website
https://jmacarbs.com/ that shows off his handiwork. You can now order and pay for the rebuilt carb of your choice
including the after market Marvel-Schleber carb that is only exceeded by Weber. JR is old school not only in his mechanical acumen but also in his business demeanor. He's pure delight to talk with, liberally shares what he knows, and best of all stands behind his work. I know this from having dealt with him now for several years where I have learned much and traveled thousands of miles on one of his rebuilt Marvels.
