Hadnt used it for a couple weeks and its stored in my garage.
Finally went fishing went to get on plane and my son says something didnt sound right. Got on plane but under full power the motor sound like it was missing, prop slipping, couldnt figure it out. It would run ok unless full power. No codes or alarms. Will idling I could hear bubbling from exhaust. After some thought, I thought poppet cover came loose. Removed side cover and sure enough it was half off. Replace and problem gone. Why would this blow out. Would a mouse or mud dauber plug up exhaust ports causing enough back pressure to make engine run bad and blow poppet cover.
