problems with holding idle

Hey guys, I started my 1991 hijet today and came outside about 10 min later and it stalled out. I thought maybe the carb wasn't warm yet so i started it up again and then the engine went to idle down, and the head lights started to dim and the car was barley running. and then it stalled out. I can get the car to fire up and drive but if i stay stationary to long the car begins to die. any ideas?

 

vacuum lines? dirty air filter? stuck choke? bad gas? points? condesor? plugs? wires? cap? rotor? coil?

 

Hey Milt....I bet you are right on what is wrong, he he.

 

thank you i was playing around with the choke and that seems to be the problem thanks again

 

Mine does that after 20 minutes of running. It is pulling a vacuum on the fuel tank. Loosen the cap to equalize the pressure and I'm good to go.
