I got one of those recent carbs on ebay. Had purchased a couple others years ago for parts so I'd have enough stuff for an original on my 31 model 619.
Thats what it came with and it run although the Tillotson seems so complex and so many moving parts. It was pretty leaky but run. i put a new Zenith on it to drive. Works great. Still have boxes of JR5's and 5A's. Metal seems Ok on some. Maybe someday...
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.
