Engine stalling

[Kip7143]

Thanks for the reply. The truck doesn’t have AC. But maybe it does have something to do with HVAC.

No shop has agreed to work on my truck… so I guess I’m on my own.

So just to recap. Rebuilt ignition and checked timing. Changed vacuum lines (one at a time to not screw them up), rebuilt carb. While inside the carb I found a bunch of carbon deposits, which someone mentioned means a failing charcoal canister. Reinstalled carb with the needle cock-eyed. It flooded the carb with fuel and pushed it to the canister and it overflowed with fuel. During this period the truck ran really nicely! But fuel was everywhere. Took carb apart, made adjustments, back on truck and still running crappy and stalling. Now the truck won’t really run for more then 5-6 seconds before stalling.

So I’m going to replace the charcoal canister completely - it is full of fuel and I found a crack on the top /side. Reinstall and check all lines going to the correct location.

Run on solenoid hasn’t been changed or checked. Could also be failing.

Lastly…. Check the entire truck for a vacuum leak. Is there another way to check it other then running it and spraying carb cleaner? It isn’t running long enough to be effective. Can I use some sort of steamer or something?

Current symptoms are runs rough, can maintain idle if holding the throttle. If not dies after 5-6 seconds.

Thanks for all your input! Going to figure this out eventually
