You need to do two things. Trust me, I had to break this news to people for years...
1. Stop trying to start it. Just 'cause you cant hear anything doesn't mean that all is OK. You could already have catastrophic damage. "Jumped timing" is a bad bad bad thing.
2. Take it to a qualified and reputable shop. Be prepared for a possible complete teardown with head, valve, and piston work. Whatever you "saved" on the purchase is already spent double.
Running by the end of the weekend is probably not gonna happen and is NOT recommended. If you can get out of this sale, please do. This will not be a pleasant experience for you.
