[AT] Need help troubleshooting engine/compressor

[charlie hill]

Cecil,  as I said earlier, there absolutely should be a warm up bypass
valve.  Is there a push button beside the ignition key (not the start button 
but
a separate one) or a 3 position switch that says off start run?

The cold natured problem seems to be typical of these.   The factorey
says I should have an idle warm up valve, there never was one .....
