I got it off amazon, it had 5 stars so I assumed it was half way decent but I guess I was wrong. but the engine I got was apparently either a really good clone of a pretty well known engine or an abandoned real one. I watched a video on the supposed original tell-tales and they seemed to match up, even the markings on the rod matched up. But sadly I don't remember the actual name of it. Also how would I go about realigning the bevel gears. If you couldn't tell I'm not very familiar with 2-strokes, I mainly work on 4-stroke go karts.
