Set your cam gears to 0 take of the belt and start from scratch. Line both gears facing up as good as you can. Make sure your crank pulley is at TDC. Now take your belt and put it around your crank pulley make sure it is tight pull it up and over your Exhaust cam take a pair of clamping pliers and clamp it inplace make sure it is tight. Then pull it over the next pulley and make sure they are both still facing up as best as you can get them clmap that one down to the pulley as well. All you have to do is make sure you get it around the water pump and tensioner with out it coming off then your done. Turn the crank pulley around 3 or 4 times to get everything to settle right check to see how close to TDC the cam pulleys are. Make sure you can turn your belt about 90 degree but it is still tight. Then all you have to do is adjust the cams from there and hopefully you are just a few degrees out.
