Engine run-in general info: per Bingelis, Mattituck KEY IS HIGH RPM, LOW TEMPS. LOW POWER AND LOW HEAT IS OK, BUT DOES NOT CONTRIBUTE TO BREAK-IN.
Pre-engine first test
Vans chapter 15, firewall forward instructions for bleeding oil pressure line
fill with 8 quarts aviation mineral oil SAE40 or 50
fill fuel tanks 10 gallons each side, fuel dip tube calibration, pressurize system and check for leaks

start on left tank, mag
test carb heat, mag drop, LSE drop
cycle prop to max 300 rpm drop
check idle RPM
full power, no more than 30 seconds
cool down at 1,000rpm for 5 minutes
check fuel selector left and right
at idle turn off mag briefly to check p-lead

Pre-fast taxi test prep
Fast taxi test
cycle prop to max 300 rpm drop
half-flaps, get going to ~35KIAS
check airspeed indicator and EFIS both showing speed
cool down at 1,000rpm for 5 minutes
Questions
what happens to rpm, sounds, etc... when turn off E-ignition in various conditions?
