Default HELP! Please,

I just purchased an advance timing light. The previous owner had paint on the time tab and pully. I sanded the paint of and can now see everything on the tab. BUT I CAN NOT FIND A DAMN MARK ON THE PULLY!!! For the life of me I can't seem to find a mark. How can I find it? Isnt it suppose to be a line cut into the pully edge?

I don't think it's on the pully, but on the harmonic balancer.

It should be a groove in the hamonic ballancer

THATS JUST GREAT, The guy painted that blue too! So I was looking on the pully edge for nothing. I figured since the points on the tab were facing the front, that the line would be in front. But there is a tiny hole in the tab behind the 3degrees. Am I suppose to find the line threw that hole? Does anyone know for sure if its a mark or a grove thats into the balancer.

Take some white paint and a small brush and fill in the groove with the paint. It will then be easy to see with light beam. mike...

Thats what I did. But theres a problem. With the timing light the mark is 1 inch below the tabe. I have the distributor turned all the way counter clockwise, it will not turn no more. I can not get the mark close to the tab. When I turn the dist. clockwise it goes even lower. Im also using the button on the back of the light. I just can't get it to the tab. What am I missing? Am I doing somthing wrong?

Did you pull the timing advance hose from distributor and plug it?

I pulled it, but did not plug it. Am I suppose to plug the vacuum on the dist. or the hose to the carb?

I plugged each sepratly, then both together = NOTHING. I have the distr. maxed all the way counter clockwise. I can get the line to go to where it's suppose to be by rev. the engine to 2200 with the vac. hose on. With the vac. hose off I can get it where its suppose to be at 3200.

The hose to the carb you want to leave alone,you want to pull the line on the pass side of distributor at the bottom and plug,then set timing at car's specs-
Do you have original timing cover,or after market?
Your distributor is HEI,right?
Sorry for the questions

Yes it is the orig. timing cover, And it is HEI. But the vac. line is connected to the DRIVERS SIDE of the carb. low. I went to check it this morning, I wanted to see about the "ported vav." and the full vac. I believe they already have it on the full. Because when the car is at idle, there is still vacuum being pulled through the hose. If it was "ported" there should not be any vacuum, untill the throttle is cracked open. Correct? I have pic's I took this morning. I will down load them. Thanks for the help...

Ok-I'm with you now
Leave hose on carb-pull that same hose off dist. and plug-you will have vacuum at idle,especially if heads/intake are ported,less air restriction due to no roughness through ports
What degrees BTC does yours call for?
Also,does timing cover have degrees marked,-ie.4,8,12 above TDC?
If you can post pics-that would be great!
Never mind on the pics!Just saw update

This is what I did this morning. I t was broken in the open position and not working. So I just took it off, and took the valve off and covered the hole. Ya think this could be causing a problem? It wasn't working to begin with though.

I sanded the tab since then to see the #'s. The sticker in the engine comp. say's 8 degrees BTC. Which would be the lowest mark on the tab. If you look an inch or so below you will see an orange paint mark. That's the line a tad below that. When the timing lights on it goes up towards the tab about an inch, but stays an inch below it!

When you look at the timing tab. 0 degrees will be the deepest notch towards engine block,as going upwards towards pass side,all outward points-towards fan will graduate as 4,8,12 BTDC.
I see the egr delete and plate,what is the top pic of?

Hold on-the mark you see isn't the one you want-the harmonic balancer-which is the wide looking pulley under timing tab is what you want,,as you turn motor,you will see a long groove cut into it from fan to block-that's the one you want.

The top pic is what I took off. (heat riser valve) Yes the orange dot I put on the pully to help me get a visual. That line is hard to see at times. The lowest point on the tab is 8 degrees BTC. That is where I need to be. But cannot get it there.

Ok-the orange dot on the belt pulley is the wrong mark.
The balancer directly under the timing tab is what you want-that's where you will find the timing mark-it's deep,all the way across it
You don't want the lowest point on tab,that's after top dead center-
You want to be at second point above "0" mark,not below,that will retard the timing

That mark is there, just a tad below that dot on the bal. The lowest point on the tab is 8 degrees BTC. Thats what the sticker says I should be at. Either way, I wish I could even get it there. Theres no way to get it anywhere in the tab! Unless the dist. can be rotated more, but it won't go anymore. Its maxed. Im thinking maybe the inards are so old that everything needs to be replaced (springs/weights) I will check it out tomm. When I get home from having the duals put on.

Yes,very possible,the weights could be shot,is this original,or has the dist.been removed and maybe a tooth off?
Or like you said-just wore out.
Hope all goes well for you
Let me know what comes out of it
