Currently having a strange CHT problem with my from cylinder number 2 on a. O-360 180 HP RV7A on take off all cylinders will climb but my hot cylinder will get well above 400F and in cruise will stay in the 190s I've recently been just burning more fuel instead of burning my cylinder, but was wondering if anyone had an idea on what we could do to maybe fix this issue. back cylinders will sit in the 380s at around 11 to 12 GPH. I have just ordered a Louver kit from vans to hopefully help with the issue. we have recently redone the baffling which helped a little bit for takeoff runs but we are thinking to do a plenum instead to help.
