Q: I have a Mattituck TMX O-360 in my Glastar. During a longer climb phase, my CHTs differ up to 100°F between Cylinder No. 1 and No. 4. Leveling off and reducing to cruise power (65%) at top of climb, CHTs stabilize all within max 30°F.
What could be the reason for this difference (airstream entering the cowl at a steeper climb angle?) and do I have to be concerned about this?
