Hi Folks,

I did the nose mod about a year ago, and flew the heck out of it, now i just got back into messing around with it.

Here is my problem... (With Zenoah G26)

I installed a new fuel tank yesterday because my old one was deteriorating around the opening. So i've got the new fuel tank installed, and it runs strong. I've got a large "clunk" inside of the tank so it can move around in there freely since the tygon tubing is so stiff. It run great straight and level, but as soon as I point the nose straight up, it dies after about 5 seconds or so. I am using a sullivan 12 oz fuel tank. I watch the fuel lines when I point the nose straight up, and air bubbles and/or gaps appear in the main fuel line, which in turn starves the engine of fuel, and makes it quit in the nose up configuration.

Does anybody have any tips to solve me problem?

Thanks for any tips,

-Danny
