I have two lines in the 12oz. Sullivan tank. One is for the klunk that goes to the bottom of the tank and the other is the vent that points up into the nipple as per the directions. I did double check the lines if I had them backwards and they are correct. I have the tank mounted as close to the motor as I can so my lines are not too long. There is a hose from the nipple on the muffler going to the vent line in the tank. The klunk line goes to my fuel adjusted valve then a hose from the valve to the carb. I have taken a separate hose connected to the fuel valve and blew air as I opened it, I could feel less resistance the more I opened it up. The same for the carb. More air I could blow through the more the more the throttle opened.
I do use an electric start motor to spin the prop. It does draw fuel pretty good with finger over th carb or not. When I do get the motor to start I been keeping the glow stick on the glow plug because the motor only will run 3-4 seconda then dies.
Im gonna try a different fuel OR try adding a little castor oil to see what happens because I keep getting mixed answers that fuel could be the issue. I'll keep you in the loop. Thank you for your answers
