Just got a new engine recently, and now I am putting the timing in its place. BUT...

It acts really funny when the leading is retarded so that it hits the first mark. It seems to be just fine when it is advanced some! When it is where it is "supposed" to be, it will gag out when I give it some gas.

But its fine advanced about... 5-10 degrees?

note 2:

It really doesn't want to hit the mark at all! I have to retard it ALL the way and it is about 2 or 3 mm off at that point. I move the CAS a tooth over and it can't be advanced enough to hit it either!

My dad thinks that the pulley has been put on backwards... but I HIGHLY doubt this. as I remember, the main pulley is 100% idiot proof. Not only that, but I would think that the car would not run at all if the timing was really off THAT much...

PS sometimes it idles @ different speeds. Most of the time the car favors either 1500 or 750. I think this may have something to do with running cold.

ANY INFO WOULD BE GREATLY APPRECIATED!!! THANKS!!!

Yes. The pulley has a staggered pattern and will only go on one way. Although, if a person was really determined and did not know about the pattern, he could with some elongation of the holes, put it on wrong. Most likely not the problem.

That said, I rebuilt an engine once and found out that no matter how I stabbed the cas, or how many teeth I off set it, the dang timing marks would not align. I thought about it for a while, and finally blamed the problem on ME. I remembered putting the timing gear on the eccentric shaft wrong. I think the champfer on the gear was supposed to face the rear or the engine and I had put it on toward the front. At least thats the conclusion I came up with.

I take it that are rotating the cas as far as it will go and the timing mark still does not align. Right? So what I did is take the cas out and grind the slot in the cas some more. I think it was only about the width of the bolt that holds it down. Now I can set my timing. It will rotate just enough to hit the mark.

Looking into the engine from the front, the pulley rotates clockwise. You are aligning the Lead with the first mark to meet the pointer, right????? I'm sure you are, just thought I'd add that just incase you were aligning with the second mark that comes around.

You do know about how you can rotate the first timing mark to match the pointer. Then pull the cas. Remove the top cover on the cas(two phillips screws). Then align the bottom marks on the cas, hold that and look in the top of the cas, and mentally note where one of the teeth is in relationship to some fixed place on the cas housing. Then stab the cas fully. Once stabbed, look in the top and see if the tooth you picked earlier is still in line with the fixed place on the housing. If not, rotate the cas body until the teeth match the fixed place on the cas housing.. Once that is done, you KNOW the bottom marks have to be aligned, not guessing.

Thats still a ballpark figure so to speak and you now need to get the timing lite out. Later.

I didn't rebuild the engine, so I would hope that the eceentric shaft timing gear is not on wrong. I would have some beef to chew with the rebuilders...

yep and yep

I do believe we(my dad n I) did this when we put everything back together.

1. line metal poker up with mark

2. line up white mark on CAS with tick on CAS hole

3. line up black end of the timing rod(?!?! not real sure of terminology here, but you know... looks like a compass..) with sensor pointing towards the car and not away.

The car likes to run a little rough too, but I think that is because of a problem with the AFM combined with break in compression levels.

EDIT: HAILERS you da man! Thanks for the help!

The part about the timing gear being put on backwards is just my GUESS on what went wrong. I was not about to take the front cover off to fix that. It just meant I had to cut the groove in the cas(the one where the hold down bolt goes) a little longer.

Here's a jpg out of a HAYNES manual on the insertion of the cas. By the way, I'm a little vague about the white marks near the cas hole you mentioned. I must be miss understanding.

Bottom line is: if your using a timing light, and get the pointer and the first mark on the pulley to align, then your home free.

Sorry. Site would not take the jpg in a timely manner. Maybe later tonite. Off.

Ok. I re-read your last post and I understand now. It seems it was put in right. If the timing marks still don't align with a timing lite, because the cas won't rotate any more because the slot on the cas isn't long enough.....then just take a rotary file/whatever to the slot and make it longer. Thats after you try stabbing it several times and it not getting any better.

To get an idea how far off you are, remember the first mark if five degrees after top dead center, and the second mark is fifteen degrees after top dead center. So its ten degrees b/t the two. Just eyeball how far you are from the first mark and compare it to the distance b/t the two marks to get an idea how far off you are

I'll try to attach the Haynes manual cas install on a jpg right now. If it does not take, no big deal. Its not very accurate or desciptive. Just doing it because I'm persistant.
