ka timing problem

hey guys…

i got a ka DOHC s13 and the engine timing is maxed out and really pissing me off. It idles so bad at lights and i can’t take it anymore. I have a timing light but dont know how to time the engine. Does anyone know the information i need for the proper timing? Also what do i have to adjust /do to get proper time… If somone could help me out that would be great…
