Thanks wrenchbender! I don't think these parts are meant to come out, at least not with some serious work involved.
As for Mike, I did e-mail him. He said the brass plug has to be in, but otherwise it sounded like he did not know.
Moved the pin back to original position; truck still getting no gas. Going to play with the float levels. Maybe that's the problem and not the pins etc. whatsoever. Will post with an update.
