I have a 1946 2 ton with a W - 1 Carter. Looked to be the original carb.

When I went to buy a rebuild kit they needed to see the carb to know if it was a YF or not.

The way they told me was that if the accelerator pump rod was round or flat.

My carb's rod was flat. Though I am not sure if that meant if it was a YF or not at this point.
