I have a 0-320 H2AD in a Little Toot. The engine has 1800 hrs on it with all compressions around 70. The #3 Cylinder on climb out or cruising is consistantly around 430 degrees (2400 rpm) all other cylinders are 325 to 350 degrees,if I pull power back to 2100 it cools down to 385 or so. I have checked the cowling, thermocouples, air intake tubes for leaks, carb linkage (fuel shutoff), etc... Lycoming said it should be 150 to 400 degrees for optimum cylinder life and never exceed 500 degrees, the hottest it's gotten is 445, oil temp runs around 195 to 200 and egt's are all normal. Has anyone run into this before? Is it normal on a 0-320? I only have about 8 hrs on the plane and don't want to hurt my engine, but I have no history on this engine to know if it's normal or not. I'm open for any help or suggestions. Thanks Steve
