You had said that you're using the flywheel method to stop it, as opposed to pinching the fuel line or smothering the stinger. I would think that with a weaker plug that would leave some fuel behind, that coupled with the local temps not beeing blazinly hot
in recent days.
I can kinda see what you're getting at but that's not going to be the issue that he's having. If you stop and think about it if you turn the engine over on the box for a few seconds without the igniter attached you still do not get enough fuel in the engine to pour out of the pipe like he was describing. What he has is a clasic pressure issue with the tank, basicaly it is pressurized by the line coming off the pipe while the engine is running. When he shuts his engine off the tank is not venting so it is under pressure still then the tank cools and shrinks which forces fuel up the line and into the engine flooding it.
