Went flying this weekend and upon doing my preflight run up I got a 300 rpm drop on the left mag. I figured it was plus due to not flying for several weeks. I flew for an hour with no problems and before shut down did another mag check with still around 300 rpm drop. Pulled the left mag plugs (all bottom plugs) and two had oil on them. Cleaned them all and reinstalled. Did another mag check and had about a 75 rpm drop. Is a little bit of oil normal after several weeks of sitting? The engine is an A65 with about 930 hrs. I plan to do a compression check this weekend to put my mind at rest.
