My RV7A was flown for it's 1st flight last Tuesday, June 17th.
The plane has the following:
Aero Sport 0360 A1A
Precision Carburetor with a "10-3878" Jet
One Light Speed Electronic ignition
One Slick Magneto
Hartzell Constant Speed Prop
Took off and flew to 3000 feet AGL and maintained:
24" Manifold Pressure
2,400 RPM
for 45 minutes
The engine had the following temps:
EGT
#1 - 1422
#2 - 1438
#3 - 1438
#4 - 1400
CHT
#1 349
#2 376
#3 401
#4 396
The engine also popped and back fired during the flight.
When taxied to a stop with RPM at 1000 and mixture pulled out to full lean the engine stopped without any RPM rise.
Does anyone have any ideas WHY the engine ran so lean?
