I have a hot running 0360 in a 9A. Out of 8 RVs I have had this is only the second one I can't seem to cool. I can see up to 430s at full power. #3 is the cool one by 60 to 70degrees and EGT cooler by 100 to 140 . I have checked timing,compression,plugs,swapped sensor,checked for intake leaks. Out of ideas. Installed AntiSplat cowl flap 2each. Looks like it lowered CHTs by about 40degrees. Still seems warm to me. It is a Titan 0360 with low compression pistons. Any ideas??? Bob [email protected]
