I dunno, man I rebuilt an A 833 with a Chilton manual and parts from Brewers, it wasn't that difficult.
I can only imagine, if everything went in correctly upon assembly that it could be improperly machined parts, or tolerances.
they out source the manufacturing to China etc.
however are the shift forks bent? what can be checked replaced without tearing the thing down again. I believe tearing it down right off the bat would be "paranoia" LOL!
