I'm New Here
Thanks in advance.
New to me 2005 build RV7 O360 - 785 hours. On take off, especially first flight of the day CHT goes up to 425 deg, 500 rpm, 17 gph FF. Subsequent flights are much better (relatively) about 400 deg. Cylinder 1,2,4 in the 350 - 380 range on take off. #3 goes to 380-390 at cruise.
The baffling seems OK About 1/2 inch drop from cowling on ramp. It’s in 3 sections. I assume it “flies” up to seal with the upper cowling since there are marks on the cowling.
There appears to be 2 washer spacer at the rear shroud of the cylinder. It’s riveted so additional space in is not really possible.
Any ideas on better air flow?
