^^ This. The reports of all kinds of nasty stuff found in these engines (including my own) are too many to list. I consider it MANDATORY to do a full tear down, and inspection of every motor that you receive, before ever putting it into service. It's just cheap insurance.

Even still, after tearing down and cleaning, fixing threads, ect. I still had my first one go south after only 5 minutes of running! Turns out the main bearings completely self destructed, ( one side even spun in the case! )

I'm still going to try and rebuild this engine, so hopefully I'll at least have a spare when this new one expires. It truly S@#ks when....
