Does Summit sell a stack of those top plate gaskets in one package? Seems to me that when I had one of the "other" versions of that "new" carb, they were a royal PITA to keep around.
Or do I have this Summit carb confused with another that seals like an Autolite?
Building another set-up, I think I'd be prone to try one of the 600cfm "Slayer" carbs...
