I've read many of the threads regarding hot cylinders. Now it's time to tackle my situation.
Engine is the 0320 with a carburetor. Cylinder #2 is the hottest. Cylinder #3 is the coldest. During climb and cruise the delta is 90-100 degrees F. I have tested the CHT's to verify they are pretty accurate.
Below is a picture. As mentioned on other threads, the #2 cylinder has an area on the front with very shallow fins and this not very efficient at shedding heat.
My guess at a solution is to reduce the amount of coverage of the aluminum shroud on the underside of the cylinder. This will only work on the portion of the cylinder closest to he engine case.
Is my solution correct? Is there a preferred solution given what I have described and shown in he picture?
