hey guys i recently put a new clutch get in my 97. I did everything the way that i seen from a video on here. But when i go to ride it, it wont move while its in gear. But when i lift up the rear end on a jack, the tires will spin as they normally would when i give it gas. Mind you that it ran and drove perfectly before i changed my clutch. What could be going wrong?!?!?!
