how do i set the timing on my car?

there are 2 ways to set the engine timing if you want to set the timing by the line marks on the sprokets you can but you have to strip the cover off to do it and it has to b pretty precise or you could remove left 2 right the spark plugs and line the engine up top dead centre from left to right giving half a turn for each
