I agree with your opinion concerning W1 vs. YF. I'd make this change if the W1s were more readily available.

Tom - I don't understand why you are having a problem finding these?????
The primary reason I started looking at the 483s/574s as aftermarket units 50 years ago is the fact they were, and still are, as common as dirt!!! (or course, dirt is more expensive than it used to be
).
At any given time, there are several cores on Ebay, I probably have 50 cores myself, as in a different lifetime, I had time to rebuild them.
As well as the carbs being common, so are parts; ever single component of the 483s/574s (with the exception of the choke cable bracket) is readily available. The brackets can be found with some looking. I cannot think of a SINGLE one-barrel carburetor ever made that has such a ready supply of parts!
Only after I starting doing lots of these, did their other attributes for multiple set-ups (leather accelerator pump, mechanical power system, and tuneability) become apparant. And of course, I have tried to use Carters for the last 60 plus years due to their metering rod technology.
