I have everything all set up in my first ever plane and a .46cubic inch glow motor to boot. The problem I'm having now is that the fuel will not siphon up the line to the motor.

I have 3 lines running into the tank, there is no leakage from the tank. One line to fill, one to the muffler and one to the engine. Everything seems to be set up the way it should be. The tank is above the nozzle on the carburator and I pinch both the other lines when I am trying to siphon the fuel to the engine by flipping the propeller. Sometimes I see some fuel make it's way... sort of up but it's full of air bubbles .. big ones .. and it can never reach the engine nozzle. I've flipped it for 5 minutes straight with my thumb over the carberator intake as well as pinching the other two lines, nothing.

If I can get past this then I'm sure it will be a cinch to get the engine to start, but so far no luck. Can anyone give me some ideas of what is causing this and what you do to get your fuel to run to your engine. Has anyone else had this sort of problem before? Could it be that the engine is too far from the tank? I've spent many hours, and have a lot of fuel stains from trying and retrying. Any ideas would be greatly appreciated!
