I had the same problem with my 408W since it likes to idle at 950+!!

So I fabricated a bracket to hold a fast idle solenoid that holds the throttle slightly open (950 RPM) when energized and allows the throttle to completely closes when the ignition is turned off.....problem solved!!

If interested it is an A/C throttle position solenoid used in older cars.....simple and inexpensive!!
