You have to have the timing belt cover that goes behind the crank in order to do ignition timing...you can manual set the timing by putting a long screwdriver into cylinder 1 and rotating it until the timing hash on the crank lines up to the mark on the block and the piston and cylinder 1 is at TDC (top dead center). Cam gears must have the word up pointing up and the hash marks lined up with eachother in the center.
