advanced timing help

[_97tsiawd_]

Ok guys so I just got my 6 bolt in my 97 and got myself a timing light. What I need to know is how do I First: set the base timing and Second: advance it about 5*
I have a 1g CAS and I know how to use that to advance it but how do I use the timing light to do so?
If anyone can just give me a quick step by step that would be awsome.

Thanks
Ryan

You do not have a distibutor. I don;t think you can time without that. Get a logger and check the spark and go off that. I wouldn't advance it to far with our interfaced motors. You'll hit the valves

YOu havent set the base time yet. YOu must resaerch before you do this or you will ruin your head. Everything has to be right. And like i said above you should try to advance it. Just get some cams and some gears and call it safe.

First, hook up the timing light to the battery and #1 spark plug wire. You then need to ground the timing adjustment connector; which is a one pin plastic connctor near the battery (vague, I know). You can then shine the light onto the harmonic balancer; there you should see the timing plate, which is essentially a piece of plastic that says T and 10 if my memory serves me right.

T is 0 degrees, or Top Dead Center while 10 is 10 degrees advance. The harmonic balancer pulley has a little notch on it which serves as the indicator and if you're set at base timing, it should appear to be between T and 10. The notch should be stable and not moving around a lot; if it is then re-ground the timing adjustment connector. If you need to adjust timing, just loosen the two bolts holding the CAS down and move it up or down to retard or advance timing according to the timing plate.

My advice to you is, don't screw around with base timing; that's why engine management systems exist.

With a 1g CAS you CAN advance the timing, Its really easy. Also a 5* advance is safe for pump fuel. I've read that pretty much everywhere.

on mine it has a "10" "5" and a "T" my manual says to start with the time notch on 5.

it says BTDC above the 10. So would I wanna start with the mark there?

Base timing for a 1G is 5 degrees, so you should start there; otherwise you'll be running 5 degrees retard throughout the whole RPM range.
