I have a problem that I cant figure out on my A75. The lower plug on the #1 cylinder majorly fouls no matter what I try. All the other plugs (upper and lower) are fine. I aggressively lean on the ground and keep the RPM at 1000 min at all times. Tried setting the idle mixture lean of peak, swapped out the leads thinking there might be a short since it only occurs on one plug. Has anyone else experience something similar? What puzzles me is that it is only the one plug. I cleaned the plug, went for a 1.2 hour flight and here is what it looks like back on the ground.
