85 olds stalls when hot

My 85 oldsmobile cutlass sierra stalls alot when its hot or driving on a warm day. Sometimes it starts again sometimes it has to cool down before i can start it. Ussually I prime the carb with gas to get it going again. Do I need a new carb or could it be something else like a timing belt???Doe this car have idle air control solonoid?
