| no stop right there!!!
first the eccentric hub adjustment is not in the hole look to the inside of the rear sprocket and theres what seems like a piece of steel that looks like it missing teeth (proably better to take pic)well
thats the adjuster but first loosen the two bolts on the hub by the side of the adujster turn it anti clock wise to tigten the chain and clock wise to slacken the chain.
the chain should have about 30mm of play when on the side stand.
not seeming to be rude but i think you should get a haynes manual.
cheers
