What year is this Harley Davidson golf cart? Helping a buddy with his cart and we're unsure of the age. Can someone help us out? Also, we had the carb apart to clean and there's a spring on the needle and seat I've seen before. We're not sure of it's function, we assume it's to help hold the float open. The cart has good spark and fuel is getting to the cylinder housing. We pulled the air filter off when turning it over and it pukes out fuel from the carb, does this mean the needle and seat are gone?
