huasheng engine diagram

[islanddave]

Hello All,

Does anyone have a decent diagram of one of these little beasts. My sons bike developed a back knock. we took it apart to find out that the connecting rod bolts have come free. Tightened them up, however i believe that the crank journal and rod bearing caps are elongated now. Gonna run it again for the **** of it (the tolerances on these engines seem to be of little consequence) The problem we now have is that we have a couple of spacers that fit on either side of the crank shaft . One is wider than the other. We cant determine which one goes on which side. A good diagram would help.

Thanks Dave
