So, this 660 is having some issue with the trans, me thinks. It'll go in 1st and it will want to move (I haven't take it out of the garage) but, I can't seem to get it into Reverse and when I put it in N I hear a loud clacking sound coming from the engine somewhere. And while that noise is happening, the countershaft sprocket kinda twitches like it wants to start turning. Is this gonna be an engine split? I've only done one engine split. I rebuilt a Honda 500 Foreman engine last year. That was kinda fun. I guess I can do this one too.
