I hear you can run it straight, but make sure you have good ventilation. I've never done it and would have some concerns about it. The only other thing I have done is add alcohol to fuel to get water out of the line however, I don't think that is your issue.
If Star Your Engine didn't work as well as your seafoam mix, you probably have something blocking the fuel.
Bart, all the above advise is pretty right on.... and there's lot of videos out there that talk about exactly what you are describing.... If you weren't 5 hours away, I'd drive over and help you out....
