Friday evening I am going to start a 1952 wrecker that has been setting since 1970 or longer. the hood has been on and motor covered. You can grab the fan and it will turn over smooth. Im going to throw in a battery clean out the carb, change the oil.. and PRAY! Any tip to do before the first turn. I know that they are a 6 volt system, can I start it with a 12 volt battery, or shoud I go get one of those tractor 6v batterys? Any bets on if it will run....???? I figure that the ring will be stuck, or possibly other stuff. If It does run, is there somn I can do to help the rings break loose? Truck only has 30k on it, and Ive been told if the flatties run... dont rebuild them, cause your asking for it. Thanks Hambers.
