My 715 wont run for anything. My dad was an Army mechanic when these trucks were new and he cant figure it out either. The truck wont run unless the choke is at least half way pulled out. Even hot it wont start without full choke, but when we adjusted it and open the choke it floods. Its driving me crazy. I have rebuilt the carb with a military surplus kit. Ive got an electric fuel pump and getting plenty of fuel. It was also missing the idle speed screw. If anyone has an extra carb id buy it but for now I gotta figure this one out. Any advice would be great.
