Backfires LOP
I would guess an ignition problem.
If neither plug fires there would be unburned fuel
in the cylinder.
LOP requires a better spark than "somewhat" ROP
which is what most people mean by ROP.
An LOP mag check at altitude will tell. APS
has opinions how to do that..

Anyone had experience with this?
Pilot flying
our IVP (TSIO550E3B with 4 blade MT) and reports:
"Had backfires(?) couple
of nights back. Was running lean of peak with
temps 1590 at FL150,
around -15C, light rain, 29Hg 2500rpm .
Happened twice so went rich
of peak for remainder of flight with no
problems. Any reason come to
mind?"
Be grateful for any thoughts
