I have just done the first annual inspection on my Lancair IV-P after
50 tacho hours of engine operation and discovered that the magneto
timing on both slicks was 28 degrees instead of the required 24 degrees
per the service manual and data plate. I have not touched the mags since
the engine was shipped from TCM.
Compression tests range from 78/80 to 74/80 and I have used under 3
quarts oil
over the 50 hours of operation.
My question is this to those engine experts out there (Walter, George),
would
this advance timing setting have had any determental effect on my engine
and
how would it present itself. I have an EDM-800 engine monitor with data
of each
flight downloaded.
