Cranked the engines on the flight table and sat the airplane on the ground yesterday. Just as the wheels touched the ground a barely perceptible change was heard in one of the engines. Put the airplane on the table and retuned the engine. The engine shut down during the next flight.

Removed the needle holder and under very close inspection a floater smaller than a human hair was found. I missed finding the floater during the last eight troublesome flights.

I don’t change glow plugs either but recently solved a problem with a very difficult to tune engine by going to a hotter plug. I had been working on the engine almost daily since May 15. Could have overhauled my car engine two times over. Very embarrassing.
