Stalling Issue (Slant Six w/Holley 1920 Carburetor)

The choke and pull off adjustments can be touchy on those. It sounds to me that you need a bit more choke tension so it stays on a bit longer. If you change that adjustment, you may need to readjust the pull off so it doesn't run too rich at start up. I've found that the factory manual adjustment specs will get you into the ballpark, but, it's usually necessary to tweak them a bit with today's gasoline.....especially our crappy Ca. fuel. It's bend some linkage time! :lol:
