FatTony - Welcome to the 'Bolt!
What a super cool project.
Doing a little zooming in on some of your later pics, there are some very interesting oddities, like the Rochester carb having a side inlet for the fuel line VS a forward facing port that we see in the usual Rochester carbs. It is surprisingly intact and I can even see the engine cover still hanging out in the back of the bus.
Looking forward to seeing more and following along with your project. Being that it's a "Bus" on an apparent "Big Bolt" chassis, it may be a good idea to post your further questions in the
Big Bolts Forum. In there, you can pose questions and requests for help on any of the technical aspects on the bus since it involves all things "Big Bolt" related. It may be easier to keep track of your questions and answers in a single forum, then more folks acquainted with "Big Bolt" issues and solutions can focus attention on helping you out.
