I've followed Landar's tutorial step by step.. But when I took the old belt off the cams they shot back.. Then someone told me I had to move the crank back to zero instead of that 50 degree mark. I'm getting mixed information, hence why I've turned to the forum to clarify before I install the new belt. The crank's position didn't move but like I said the cams sprung back in a CCW direction. If you need more info from me, please let me know.
