I'd rebuild the carb, it' cheap and easy ,if it's a stock carb it's a rochester model B. Rebuilding kits are at the FLAPS for about 20.00 bucks or start looking for a carter model YF 2101s thats auto choke for that year engine.
Take the # off the carb and order the right rebuilding kit,Carb King on this site sells kits also and may be able to help locate a replacement carb ,I run carters on my truck and I feel they are a better carb, but there are alot of rochesters out there that run good ,but for now I'd rebuild the carb you have,you might be happy with it .
