Re: Stalling with choke out
My ww had a vacuum leak so it would idle faster on choke. Unless you convert to a more modern carb like a Holley 2 barrel or 4 barrel, the choke is made for starting the motor and then being pushed in so the engine can idle(my experience anyhow). Unless it's 10 degrees out then you'll probably need choke to richen the mixture. Cold engines love rich starts. If you watch this video of my cold start you'll see my choke all the way out and I immediately push it in, BUT my 4 barrel has a throttle advance mechanism on the choke that can be adjusted by a screw. What this does is as the choke is closed it opens the throttle. So at 1/4 choke I can warm up the truck at 700 RPM and walk away.
