Another pic of the valve next to the Warmup compensator. You can test the valve efficiency by warming the engine first to temp. Then take off one of the the hoses from the valve and block one of the inlet of the valve with a corck or similar, reconnect the hose and start the engine. The revs should drop to 600-700 rpm. You might need to adjust the idle screw clockwise to lower revs anti to rise them.
