This weekend I messed with the car some more. It seems to be fixed now! I changed the plugs and it appears to have done the trick. He had Autolites in it and I replaced them with Champions and the car seems to like them much better. The plugs he had in were pretty dark with carbon so I’m a little worried about that. He said he put new plugs in but I’m not sure that he really did. I don’t know how the plugs could have been working fine before it sat for a few weeks and then stopped working so that bothers me. So now I have to get it licensed and insured and start driving it and hope it continues running good. Thanks again to everyone for all the help!
