as said condenser. You can find out if there is a sticky valve at idle with a vacuum gauge. I have a full time vacuum in the 36 cab also to test load vacuum. If so you know the treatment. MMO dump on the carb and run it then repeat. If you have an aversion to MMO (not sure why) a little diesel fuel might work too, maybe. I don't want to to be one sided (mmo will work and do no harm). Could be anything really.
