I have one question, do you have the stock (type) fuel pump on the engine and 1 inline electric fuel pump? I can understand your desire to make progress while you have time and waiting on answers from us takes valuable time away from making it run. You will find bartamos to be a very methodical person who gets easily frustrated when his suggestions are not followed to the letter. He’s a good guy and will help if you let him. You are on the right track towards making it run just off track with him. If you have free unrestricted flow of fuel out of the tank fitting then work your way towards the carburetor section by section until you have flow all the way. Just a note: the fuel pumps, both mechanical and electric, purchased today are hit and miss with getting a good one. One step at a time and you’ll be back to driving soon.
