Hi Wayne .. the 1931 US 619 used the J5A which wasn't used here. Oddly our 1931 / 32 Dominion cars used J4A, J6A and J7A or could use W8A. Jon the carb king had never heard of our carbs. My 32 614 has the J4A.
Where Are You From? Ottawa Ontario
Do You own a car built by Durant? Dominion built 1932 614 sedan
