I just herd that some guys are setting up their clunk so it can flip to the front of the tank on purpose to prevent the engine from stalling on down lines. I have always made my clunk lines on my glow planes so it could not flip forward and cause a pinch in the line. Are any of you allowing the clunk to go forward like this? I set up my edge so it wouldn't go forward figuring that with almost 2 feet of fuel line it would take a very long down line to run out of gas and cause a flame out. Is there any reason I should rethink that logic?
