Thanks for the words of encouragement. I got it running and idling today. Turns out it wasn't anything to do with the vacuum system, rather the carb needed to be adjusted a bit. Now to figure out why my electric fan conversion isnt working. I suspect some mysterious electrical gremlin is playing tricks on me. Cant wait now until I can start to clean up and fix the interior. Aesthetic items are always so much more pleasing to work on.
