The girl in my senior project group said that she took a look at the fuel tank on the Honda and there was a venting valve that was a little confusing as to what was the fully open position so she adjusted that and heard a noise like some air rushing in. She took it for a test ride and it was fine, so it looks like that vent may not have been all the way open and the fuel tank was getting a vacuum pulled on it, causing it to stall and not start for a while.

I never thought of that -- mostly because I have never seen a valve like that for venting a fuel tank. Just charcoal canisters or open vent lines.
