ok well i am a bit jealous of a steady 2000 RPM idle. thanks for the tip. i will check that seal as well as others. i flew the plane twice today. set the idle up a bit to about 3000 rpm. it "killed" both times when throttling back to land. i was over the runway so no big deal. it runs great at mid and full throttle and all in between.just frustrating that i cannot seem to dependupon the engineat idle.
