Jim, I have 2 Barry Grant 850 blower carbs, boost referenced, adjustable air bleeds, etc. All the trick mods. I just had The Carb Shop re-bush the throttle shafts. I've added chrome bowls and have the original bowls. I want $600.00 for the pair. Let me know if you're interested. E-mail me at .....jockorace@tds.net
I can then send you pics. Dave
