no it should crank over w.o. gas but make sure there is oil in it. if not its prolly siezed up and your fucked. so make sure there is oil. oh and make sure everything is workable. if it loooks like its going to be hard to fix, it will be. so if everything is rusted and shit then just leave it. 500 is a good price but just know you will put alot of money into it. and it will take a good couple summers to work on it. unless u have a heated garage. be carful. really look everything over before u buy it.
