WHEN POWER WAS APPLIED AFTER A LONG 20 MILE DESCENT THE ENGINE WOULD NOT RESPOND EXCEPT FOR A "CHUGGING IDLE." THE PILOT STATED THAT HE DID USE SOME CARBURETOR HEAT DURING THE EARLY PART OF THE DESCENT. FAA ADVISORY CIRCULAR AC-20-113 RECOMMENDS "HEAT SHOULD BE APPLIED FOR A SHORT TIME BEFORE BEGINNING A PROLONGED DESCENT." ALSO "POWER LEVER ADVANCEMENT SHOULD BE PERFORMED PERIODICALLY DURING DESCENT TO ASSURE THAT POWER CAN BE ACHIEVED."
