LOL. Shoot, at this point, if you guys told me it was the brakes, I'd  
probably check that too. I need to get this thing on the road! I'm  
trying to think what's left on the electrical/ignition side of things  
that hasn't been checked; distributor? voltage regulator? Those kind  
of seem like long shots. But yeah, for the first time, today it felt  
like a fuel issue.
