I am having some fuel issues with my OS .46 engine. It is installed in a World Models Mach 1 plane. It has not been right since I crashed my last model in the dirt. The engine was cleaned out thoroughly with WD-40. The engine can be started but the turning the high speed needle has no effect. I assume I am getting too much air in the carberator. The engine runs to a point if primed well. I do not think I am getting enough fuel in the line.


I have a three line tank. I have one line going into the carberator, one into the exhaust, and on that is capped off where I fill the tank. One other odd thing is I can fill the tank but I can not pump the fuel out. Has anyone had this situation before? Any help would be greatly appreciatted?
