RV7A with O360 and C/S prop.
Recent change of behavior, coincides with warmer weather, on power up for takeoff engine dies then goes to full power. CHT and EGT's are excellent for rest of flight.
Next occurance occurs on downwind , low manifold pressure, I get the usual popping, especially if the airspeed is too high.
I know the popping is a characteristic of this engine, however, it is almost as if the engine died for a moment, enough so that I turned toward the runway before it recovered momentarily.
The manifold pressure is around 11 inches and rpm around 2000, airspeed approx 100 mph.
In colder weather I would get the popping on downwind if the throttle was reduced too quickly, this new behaviour during warmer weather occures even if the throttle is slowly reduced and the motor feels as if it stops momentarily
Any thoughts?
