      Thanks for watching and the feedback.

      Yah the cowling rattles in the back, Haven’t got around to that yet, still trying to make it run. I’m new to dual line pressure tanks. It primes up fine (i haven’t tried priming while running). When it dies and i prime the tank it is soft and i can prime it and see fuel flowing into the carb. This leads me to believe its something with the fuel system but as to being new on this style tank, I’m not sure where to look. Ive replaced the o-rings in the connector already and when i remove the tank cap it is pressurized and can hear the vapor escaping. I have also replaced at fuel and vacuum lines with new gear clamps on the fittings.

        Edit:
        I’ve also tried backing the slow speed needle in and out to no noticeable effect. It may be that it doesn’t run long enough for the adjustment to take effect.

          It takes a bit of running to pressurize the tank enough, especially if it is almost empty. It should build to significant pressure. Another possible thing is the fuel filter may be partially clogged.

            What is an average for a bit of running? My tank is between 1/4 and 1/2. It will run for about 45-60 secs. Thats without re priming. I haven’t been able to get outside to test if it helps to push the plunger down while running or not yet.
