Hello Gents
A friend today did his first flight on his RV-9 and shortly after take-off ( 300 feet) the engine started running very rough to the point that he tought about landing it in a nearby field ..
He is an experience airline pilot so he didn't panic, kept on flying the aircraft and troubleshoot as best as he could at the moment.
He started by leaning the mixture a little ( fuel press went to 32 PSI on a carburated engine (should be around 3.5 to 5 psi ) which improved the engine condition. He did a tight circuit and landed the aircraft without any damages..
On the ground they did check the timing and everything was fine on this point.
They did multiples run-ups and found out that it was impossible to lean the engine at around a 1000 RPM and full power...
A new carburator and mechanical fuel pump is on the way from the overhaul shop..
I also suggested to him to check if he had the proper ''Boost Pump'' for a carburated engine ( could possibly have one for an injected engine )
So anyone with ideas on what may have been the problem??
Thanks you for your feddbacks
