A few more tips while we are here -

Max N1 - should be checked. There is a tool for the job that goes between the FCU arm and the stop to save you having to run the engine at Max N1. Important on singles operated at high altitude. VERY important on twins.

IDLE setting. Sometimes the airframe rigging masks the true idle setting. You dont want the idle setting too low. Check on shutdown by releasing the idle detent and slowly reduce the N1 and note the N1 at fuel cutoff.

Slam decel. N2 100% flat pitch stabilised, slam the throttle to idle. Check that N1 does not decrease below 65% under 2 seconds. If so deceleration is too lean and may cause flame out in flight.

Check for wear in throttle control. Engine shutdown - check IDLE position is correct on increase direction and is close to the same on decrease direction. There is a limit.
