Quick question for the A and P crowd....been flying my 6A for 3 year or so...about 170 hours on an Aerosport O-360-A2A...my CHTs were higher initially (on all cylinders) ...up to 450 in climb...about 390 in cruise....I added the vents to the bottom of the cowl and they dropped significantly to 350-380.....lately (last 5 hours or so) my #3 CHT is much higher (up to 100 deg higher) in climb and about 80 higher in cruise. Cruise is about 330-350 on 1,2,and 4 with #3 at about 435-440. Aerosport says its most likely a baffel issue. I just did the conditional and compression is good on the cylinder and the baffeling is still in great shape...any ideas?
