I have just broken it my cv-rx on my evader adn it wont start after I ran 5 tanks through it. The fuel it going to the carb and the glow starter is fine. Also the glow plug lights up too. Could it have anything to do with it running to lean? If I richen the carb will it start easier? Closing the needle on the carb means its getting leaner right?

no u want to run it rich till its all the way broken in. after its all the way broken in u will see it start to crank out alot when stopping that swhen you need to decrease it some....... try that

ok, have to do that tommorrow, too dark at my house right now.

would it have hurt the engine if I had been leaning out the engine during break in. Also would hurt the engine if I revved it up a little too high during break in. Just a question

I could be wrong but during break in you should just let it idle through the 5 tanks not give it gas. That what i was told to do and my engine is in great condition. I have had it for 3 years now.

In my opinion the only way to break in an engine is heat cycle! I think you will find out that most people that have been in this hobby for some time will agree. All so when breaking in an engine it is not uncommon to have to lean it out some but only enough to make or keep it running. If you read most direction on motors they will say this.

Heat cycle do a search on this form.
