I have O-360 that runs fine, compressions in the 70's, and just replaced intake rubbers and gaskets. Cylinder #3 runs about 150 degrees hotter than the coolest cylinder. The CHT's all seem to be the same. I could probably save an extra gallon per hour if I could get #3 down. All the other cylinders run about the same EGT (with 15-20 degrees of each other). In cruise I run 70 degrees rich of peak and cylinder #3 peaks first. Also to note is on decent, if I pull throttle back and do not touch mixture, then cylinder #3 climbs into the 1500 degree range, CHT is normal and the other cylinders EGT drop slightly. I swapped EGT's on #3 and #4 to rule out a sensor issue.
Is this just the nature of a carb and the fuel distribution charictoristics or should I investigate a little more?
