I'm still working on solving my headlight and horn issues but now have another one to deal with.

I started the truck ('50 217) and let it run for about 5 or 10 minutes before heading out. I drove about a mile to get some gas for the lawn mower. While filling a 2 gallon can I let the truck idle.

At about halfway home the truck started dying as if there was a bog or flat spot in the carburetor. When I let off the gas it smoothed out a little and I continued a short distance before the "bog" happened again and the truck quit. I got it started briefly a couple time by priming it with gas from my mower can.

It started with a lot of difficulty before dying.

It's sitting in the Walmart parking lot now. I'm giving it an hour to cool down before I walk back over there and try to start it.

If it starts and runs, I guess I'll have my answer on the vapor lock question but who knows? The carb is recently rebuilt and the fuel pump is new. New doesn't mean what it used to, though.

I'd appreciate any thoughts on this.

Do these trucks have a propensity for vapor lock? Should I suspect the fuel pump? Did I mess up the carburetor rebuild?

Bad accelerator pump? No fuel squirted when I worked it manually but it may have evaporated out.
