Today I was determined to figure out where and why the cowling was fouling on #2 and #4 cylinder. Basically the left side of the engine doesn’t quite fit. The cowling is very tight already and the right side has about 3/8″ clearance from the cowling the left side is zero. I spent about 3 hours trying to measure and figure out a way to make it not foul but left the airport very frustrated.
Time spent today 3 hours. Total time spent on the mod 18 hours.
