I have a nexstar with the 46 fx engine. I went out for my first flight with my instructor yesterday and it was great. We had a ton of engine problems though. My instructor says that the engine is just breaking in but man this is getting to be a pain. We're having trouble getting it to idle, and the engine is cutting out alot. I ran a tank of gas through it today in my driveway and took some temp. readings. Running it rich it gets to 200 f. If I lean the engine out it climbed to 285 f. I'm just wondering manily if anyone has any break in suggestions and what temp is too high for this engine. Thanks
