We’ve got a C172 with a Lycoming O-320 engine and it’s having all sort of problems after the aircraft came from a major overhaul. The biggest issue is with the engine.. On the ground, at idle and high power all works fine, but when flying, at a certain point the engine starts misfiring at no particular time or engine thrust.We’ve changed both magnetos, all plugs, leads, cleaned carburettor, checked compression of each piston and still is misfiring.
Just for reference, aircraft flies at about 1500ft, and the average temperature is 27degC
Anyone ever had this problem, or maybe someone knows of any solution?
Any help would be appreciate
