The engine has good compression. lat time a ran it the tepmature was normal. I do havE a feul filter that could block fuel but the engine was spittingb out pure feul so i think it gets enough. no clue about bearings. i havent found an air leakedge. and i run traxxas top fuel as regular for me.
Sorry I should have been more clear, I meant compression when your engine is hot. It varies from when it is hot to cold since the metal expands.
It could be possible that your fuel went bad also. It would be good to try some fuel that you know works, maybe testing yours in another car, or have a friend with some fuel that he runs...
