Here in the Phoenix area, summer comes early. My hangered 2012 RV-12, 400 hrs is beginning to be hard to start. It always does, at the hanger, either by trying all combinations of choke/throttle, or a hair dryer through the oil flap for about 5 minutes. Any suggestions? Could it be the ignition modules? and, does it help to keep the battery on an Odyssey charger when in hanger? Help Mark
