Thanks for the replies. We had to replace the fuel pump, but it runs now. Sounds really good. We also replaced the plugs and wires and changed the oil. Two of the plugs were original and had never been changed (been on since 66). They didn't want to come out too easily haha. Figured out the breaks don't work though-- at all. Do we just need to replace the cylinders? That's what my dad said we need to do. I just want to make sure. Also, if that is what needs to be replaced, is there a specific kind I should get since it may have some large loads on it sometimes, or will any kind work? I don't know much at all about things like this..... Thanks
