May I please suggest that we all NEVER AGAIN CLEAN THE AIR FILTER and reuse it!
After one such cleaning, my filter shed enough fibers to clog the mixture plate (or the tube to it) during the next flight. The engine started running very rough since it was too lean, improving somewhat with carb heat that richened the mixture some. I think this flying for 10 minutes with detonation caused the problems for which we soon had to tear down the engine. I've changed to the Brackett filter and I urge everyone else to change away from the fiber filter unless someone can cite problems with them that are worse.
