Spinning the rear wheel backwards is supposed to move the drive train too.
Yeah, I think the chain not being in a straight line is what was causing the chain to go slack, it seems ok since I tightened the wheel and got it straight. I did know that turning the wheel backword will move the whole drive train, like I said it was doing it moving the wheel in a forward direction.
