Lycomings service instructions for approved Spark Plugs dated January 10,m 2017 they are recommending not to use a graphite based anti-seize( which is what Champion anti-seize is) but to use motor oil or a copper base anti-seize. Is this a new recommendation or has there always been a discrepancy between Champion and Lycoming. What flavor of lube on the plugs are you all using? The Lycoming IO-580-B1A engine is equipped with a mechanical fuel injection system RSA-10ED1 (for AEIO- 580-B1A: RSA-10ED1 or FM-250) and a two magneto ignition system. For alternate injection systems see latest revision of Lycoming Service Instruction 1532, for approved ignition systems see latest revision of Lycoming Service Instruction 1443. Of Service Instruction No. Rotate top and bottom spark plugs every 25 to 50 hours. Top plugs scavenge better than bottom. Proper adjustment of the idle speed (600 to 650 RPM) fuel mixture and maintenance of the inĀ duction air system will ensure smooth engine operation and eliminate excessively rich fuel/air mixtures.at idle speeds.
