Abstract
In an internal combustion engine carburetor the idle mixture adjusting valve is supported in a guide member. A sleeve slides on the guide member and carries a closure portion engageable with a seat surrounding the idle fuel discharge port. A solenoid energized during deceleration moves the sleeve to engage the closure portion with the seat and interrupt fuel flow through the discharge orifice.
