<VV> Wagon stalls when cold

Engine starts, so choke is OK.
Engine runs after warm up, so major carb circuits are OK, and idle
speed/mixture is OK.
Check the choke pull off adjustment, too rich or too lean here will
affect mixture on warm up.
And, check fast idle adjustment. In fact, just bend it a little to speed
up the idle and see if the problem goes away. Once warm, this will not
affect idle speed.
And you might want to richen the choke slightly also, maybe a turn or
two on the rod. They will start easily with the choke just closing, but
GM wanted an extra two turns closed on the rod.

>Engine starts on the first crank and stays running, but it stalls when going into gear. It restarts easily at any point in the warmup. Once warmed up - about 5 minutes of idling, chokes open, and at normal idle speed - it runs just fine. If it was a stick I could probably drive it as is, but with the PG it's got to be better.
