I'm breaking in a new Saito 180 on an Edge 540 (H9). Things were going great until I taxied in from a flight today. This was about the 8th flight on the bird, and the 12th engine run. It sounded like a washing machine with a bad belt. It runs oK, though power seems to be off, but this loud metalic squeeking indicates some sort of trouble.

Anyone experience this?
