Step by step guide to ignition timing?

Can anyone lay it out straight for me, I have access to a timing gun but haven't done it for at least ten years.
Have done a search but couldn't find anything useful.
Cheers, Raz

Very simple, visually the same principle as your S13 on the bottom pulley:

Undo a 10mm bolt locking the distributor and move it to the left to retard it or to the right to advance it.

15 deg's BTDC

Is 15degrees BTDC the stock setting please?

Hey all.....sorry for the threadromancy,but i have a quick timing related question.

I picked up an s12 auto at the weekend and it was having running problems....not helped by the dizzy being loose!

Obviously,i need to set the timing,so....Is it set using no1 or no4 on firing stroke? I've had a look in the manual,but it didn't seem to say...

Cheers..
