Timing for 91 Trooper

Hey there all,
Does anyone have/know of place that I can go online to get instructions on
how to time a 1991 2.6 liter Trooper II? I have a timing light and all, but
I want to make sure that I am doing it correctly. I put the light on the
marks, but the nick in the pulley was quite a bit off. I'm sure there is an
advance that I should disconnect. There are three marks on the pulley.
Which one should I be using??

Any help and/or info would be greatly appreciated. Oh, and I did a lot of
searching and browsing through various Usenet groups before posting. I
couldn't find any pertinent information.

Thanks,
Kyle
