Re: 1968 C2500 engine dying

After I drive a few miles and engine is warming up, when I push in the clutch, the engine dies. I'm able to restart by letting the clutch out. Pulling into a parking space at the end of my trip (about 3-4 miles) it died again. When I came out an hour later, it started fine. This time on the way home, it did not die.

I rebuilt the carb last winter and performed a tune up. It hasn't died all summer, but just started as the temp has dropped.

Any suggestions would be appreciated.
Sounds like you might be "Icing" up which some choke adjustment should solve
