On my 90hp 4 cyl outboard there is a device on top of the upper carborator that apperars to be a fuel solenoid. On it is a small red knob and a air valve like you would find on a tire. Can someone tell me what the adjuster and the valve is for? Is is not covered in my book. Turning the valvecounter clock wise will kill the engine.
