Bill, I just don't know how to answer that.

Mike, it's been 70-80 degrees here in Texas the past couple of weeks
and low humidity. And it ran fine after starting cold with the Weber
on it a week ago.

I did check on the choke pull-off earlier today, it doesn't seem to be
functioning correctly (though I can't figure out what could possibly
be causing it to malfunction). I started my engine today, let it
rumble for a few seconds and stall, then I wedged the choke plate open
about 1/4 inch, started it, and it ran perfectly at fast idle. Then,
around 120 degrees I pulled the wedge out of the choke and it settled
down to its curb idle. Seems to run fine if I manually do the job of
my choke pull-off. The vacuum hose on it is brand new. Anything I
can do or test?

Bill I might have just understood your question. I replaced it
because my Weber was falling apart. The idle mixture screw was
missing, I was getting 8mpg, and for the life of me I couldn't
maintain 70mph on a flat highway with no wind. Also, I have to pass
my emissions inspection this month and my exhaust made me slightly
woozy. As Mike argues, the Carter will run fine with some minor
adjustments. The Weber, it was old, and I wanted to go back to my
stock setup.

When the engine first starts, there is a choke pull off valve that pulls
open the choke just slightly so it doesn't chug out.

This valve is on the choke side of the carb and is hooked to direct
manifold vacuum via the nipple that is dead center and the bottom back
of the carb.

To test this, you can unplug the line to the carb base and suck on the
line. The pull off is supposed to hold vacuum.

When this pull off is working right, it should open the choke between
0.130 and 0.140 inches open as soon as the engine turns on. The setting
calls for the choke to be turned rich 'while it is being set', that is
just to make sure there isn't any slop in the main choke linkage which
would allow the choke to open too much.

This choke pull off is powerful. It will pull my manual choke cable
handle in as it fires up. I can feel the cable move.
