Im trying to rotate my cam chain for timing. Is the spindle supposed to be able to pull out a little bit? It has about I will spin the spindle and once in while the cam chain will rotate. But will usually stop. I just looked and it looks like it needs to go inside about 6mm. http://i5.photobucket.com/albums/y198/cosanostra315/Bike/photo-1.jpg http://i5.photobucket.com/albums/y198/cosanostra315/Bike/1234.jpg
