not sure about the spring, 2 different gauges tell me 3psi. tested bowl off of carb, ran 5psi air thru fuel inlet, pushed float up gently, needle shut off air flow as soon as it seated.
don't know what else to try. leaning towards flaw in bowl. going to try buddies carb, we'll see what happens. i will let you all know.
