I think I've got a problem with the chain tensioner! I've got all the cams adn timing lined up, however when i come to put the camchain tensioner in the metal rod clipped onto the plastic runner does not move up when i tighten the bolt up! Its fine when its not mounted the tensioner moves up the notches. SO i just dont know what is going/i'm doing wrong???

The chain is still slack which I dont think it should be?
