Re: Truck won't idle
It could have developed a vacuum leak. Check all rubber hoses, caps, plugs, carb bolts, gaskets & intake ports for leaks. The choke trick does work. You can use your hand or the actual choke.
If not vacuum (you can test with carb cleaner or propane), then the carb probably.
There a slight chance that the gas cap is not venting but that should show up at high rev also.
