RV-9A. O-320, FP. I would like to stay below CHT 400F on extended climbs, but #2 is my challenge. I have the dam cut down to about 1” and bent a smidge forward to even cruise CHT which is good, and I’ve got a one washer gap in place with RTV blocking the wasted area. While the three other cylinders climb at Vy below 400F, #2 runs 20F to 30F hotter. At Vy + 10kts, it’s a pretty consistently 15F higher than the other three. For all I know it could be mixture distribution. In cruise #2 peaks second when going LOP.
I’m not sure this is really a problem, as I’ve never seen higher than 420F on #2 in extended climbs, but this is a pretty experienced group. I’d appreciate the feedback.
