Got timing?
Well, today I pulled out the inductive timing light and checked my timing... And guess what, I tried to adjust it, but ran into problems...
First of all, the previous owner "forgot" to secure the battery down and thus acid spilled all over everything, including the pulleys. Since the pulleys are all rusted, I cannot tell which timing mark is which. I can see only 2 notches. I have an 85 GS with RB street port exhaust and RB intake housing. I believe the two notches are the trailing and leading notches (duh)... Viewing from the front right tire side with the inductive light, the leading (if i remember correctly) notch is closer to me (and the pin is right over the notch)--the other notch that I can see is farther away from me. Is this right? Since my leading timing is right on the notch (if that is the correct notch), I left it alone. But my trailing notch is off... I tried to adjust it but the thing that adjusts the trailing only moves so much--I needed to push it in more but it will not let me.
Is this the wrong way to adjust it? I know that the trailing is important in high RPMs... I've tried to do some research and discovered (I think) that there is supposed to be 3 notches (?). I can't find the third notch...
Anyway, what should I do to fix my trailing timing?
Thanx

On the stock pully there is only two notches. The first one zero degrees the second is twenty degrees after top dead center. (Looking at the pully from the spark plug side of the motor with the top of the pully rotating towards you)
To set you timing to the factory spec. discounect the vacume advances and plug off the hoses. With the engine warm set the lead timing to the first notch, and tighten the distributor. Then set the trailing, via the adjusting screws on the vacum andvance "deal".
The reason you think you have to push it further is because you have the vacume advance still hooked up. If you want info on tunning your ignition go to Yaw Power Products http://personal.riverusers.com/~yawpower/
