Yep, it gets pinned wide open, without out much freeplay at all.

Yeah, but the parts I'm refering to aren't clearly labeled, but since
we're on the same page, look at part #31, and go straight down to that
un-numbered screw. That's what I turned, and I beleive that's Fig 3.16
part #2. Screwing it in pushed on the linkage linked to the cam thing
with the notches.  The cam rotates down, allowing the arm that attches
to the spiral spring to rotate all the way down so the choke flap is
free to close. I believe this is the "fast idle cam", fig 3.15 part #2.

The right carb responds the same way, but the choke flap is not
prevented from closing by the cam at all.

That's my fault. I looked at it breifly as the sun was setting and
could've done a bit more research to find those part names. I hope I'm
making more sense this time.

This is a recent thing, but it sat for 3 years, and hasn't been driven
much since.
