Hi everybody,
I need to seek advise.....
Three days ago, I was out for a normal local flight and everything appeared to be normal. Then, from one moment to the other, the engine was starting to run rough. Oil pressure and oil temps were both fine. All temps were ok as well, except for EGT and CHT on cylinder 4. These haven fallen rapidly to 150?F / 117?F (EGT/CHT). I landed and returned to the airfield the next day. I checked the compression by turning the prop (w/o ignition of course, lean and fuel off) and it felt ok. I checked both sparking plugs and they seemed to be alright as well. I checked the vent springs and the vent movement from the outside, all good. When I again turned on the engine to check I was still facing the same issue...
Any idea what has happened? And how to solve this?
Thanks so much for your support,
