The small carb sounds like one for a 144/170 I-6. The larger with glass bowl fits the description of a Model 1904 for 215/223. It would be a List 1415-A, which should be on the carb. Ford number is EBP9510. Check the center to center dimension of the base holes for match to intake. Also look for throttle linkage compatibility. But the 1904 is the model you want. As for jet size, dont know. 66 seems too big. Try 58, if too rich then 53, and step down until plugs look good.

If you wait a couple days, I have a 1904 in the shop I've been meaning to get to, and can see what it has for a jet.
