When I start the engine it runs fine. I get it up to peak rpm and then turn the needle valve out a little so it is not running lean. When I face the nose up the engine runs fine. But when I point the nose down it starts to die, not instanly but a few seconds. It seems that the fuel cannot get to the engine when it is pointed down. Is there a way I can do the hose inside the tanks so it can draw the fuel out when the nose is pointed down..If I am missing something please help....Thanks Shawn
