I know this is not RC related but talk about cheap China made engines.

A friend of mine bought one of the China made about 2000 watt generaters that sell for about $300.00.

Has a seal leaking and I broke it down today, 4 Stroke with cam, The cam has no bearings or bushings, Just rides in a machines part of the cast aluminum, Now dont you know you will get a lot of hours out of this thing. LOL

Plus there is nothing to hold the seal, Can install it from either side so it is just floating around, I think that is why it was leaking, It was half way out of the crank case when I took the case apart.
