A lemon law is for a car dealer, only , when you buy from a private party, its bought as is, if they didnt give a warrenty, so that means that you dont have any recourse, but to fix it your self , and after 60 days , thats to long a time for the other person to have known that it was bad, no one can know when a head gasket or any other gasket will blow, thats not possible, in the car world , hope this helps
