    Subject: High CHTS Cylnder Baffles for 3 & 4
    Hi, Gary Vogt mentions a mod to the wraparound metal baffling for Cylinders 3 & 4 , we are working on getting our High CHTS under control and attacking it step by step. Flexible baffling work is finished and has helped ~ 20 degrees. Gary mentioned trimming of the wraparound cylinder baffling for # 3&4 that helps with the cooling of those cylinders? Anyone have details on that. We have a O-320-E2G engine (77 Cheetah) with the 150 HP HC STC and short stack powerflow exhaust Thanks in Advance Cheers, Bill Chambers

IOW, shortening the end of the baffle that wraps around the back side of #3/#4. You will have to ask him about how much, probably .75-1.0 in. Cliff
