The fuel Servo on the IO320B1A/Acroduster Too is running fine but is getting "old". 18+ years old, Bendix suggests OH @ 20 years. Question:
Are there any signs when a fuel injection servo is getting "tired"?
I have noted I'm using a lot of gas. It runs rich, requires leaning over 1000 rpm. I lean during taxi and run-up. In a 100 mph IAS climb at full throttle I turn 2450-2500 rpm full rich and will gain 150 rpm leaning to peak.
Engine is off a Twin Comanche. I called an old friend who use to have one(two engines)
. He said he always aggressively leaned...Probably normal?
Thanks,
Jack
