Ignition Checks at Various RPMs?
Occasionally I would like to verify the independent operation of each of the ignition modules on my 912 ULS at times and RPMs other than during the usual 4,000 RPM run-up. Is there any danger to the engine if I perform an ignition check at 2,000 RPM?, 3,000 RPM?, 5,500 RPM?, etc?
I know that an after-fire event in the exhaust system is typically a concern on some engines if too much unburned fuel is introduced into the exhaust system following an ignition check at high RPMs. Any concern here for the 912 ULS?
Thanks -- David
