Recently my A65 decided it was time to give me some work. I seem to have a rough running engine, on the mag checks I get no drop on the right and 100rpm drop on the left. Just changed the lower plugs, top plugs look good. Max RPM in flight is around 2150 whereas I normally get upwards of 2250. Anyone else ever run into this type of a problem.
