Thanks DADS50. I will save that list. But, some additional search over a second coffee, I found it is a Willys carb for a 4 or 6 cylinder according to Mike's Carburetor Shop web site, used from 1950 to 1960. Even though a Willys, I might still see how it works on my 261. Engine is in the frame, but not driven yet, so I don't think trying the carb at idle or short revs will hurt anything or am I wrong about that?
