My 69 Arrow 200 is running low CHTs. At mid levels I see 270-280 degrees and at altitude 305-310 max.
During take off the hottest cylinder rarely ever gets above 350-360. These are all summer time temperatures.
I read an article about ideal CHT being somewhere around 325 or more in cruise, to minimize stuck valve problems. I am actually struggling to keep my Arrow's CHT high enough. Does anyone have the same problem?
I even thought of partially blocking the engine vent on the low left side of the cowling to try out.
