Just changed out the fuel restrictions on cyl#3 and #4 on my RV-10 from an 0.028 to a 0.027. Test flight shows a very brief EGT drop(3 to 5 seconds) while going through the leaning operation on cylinder #3 only. Cylinder #3 drops about 200 degrees below the others(1200F vs 1400F) for the 3 to 5 seconds and then recovers with no further fluctuations. This repeats anytime going back through a leaning operation at different altitudes and engine settings. Never seen this before- anyone have any thoughts?
