Place the inductive pickup on the spark plug wire for cylinder #1, and look down the gun sight (as stated). Whenever the light flashes, you will see something like this:

----|-|-|----------------------------------|--------------------------

The middle in the group of three is 16 degrees BTDC.</TD></TR></TABLE>
Is the timing marks on the the crank pulley both sohc and dohc the same?

crazyguy

yeah u align tdc mark on crank pulley and on the block and also tdc mark on cam gear. it is pretty easy. u dont need to worry about degree

That's for mechanical timing, but when you are adjusting the distributor timing you need to do it this way. I believe you also need to jumper a fuse or something to disable timing advance while you are doing this, I've never done it so I don't know for sure.

mortificationrock

That's correct.And its not a fuse you have to jump its the service plug(as In the plug u jump when checking codes).You have to jump it while trying to set ignition timing.Also I believe that the mark should be, 12,14,16.Atleast in 92-95 it is.Base timing is 14* I believe.Anyone correct me if im wrong.

Yes this is correct, i have the timing set to 12btdc (thats the specs in the haynes manuel) but when i unplugged the jumper in the service connector and drove my car this morning it felt sluggish and not as responsive as it was. I believe the timing should be set on the middle mark out of the three (16btdc) I believe that is the base timing.

What year is your car? If its a EJ8 its suppose to be 12btdc.Which im wondering about too.And no its not 14,16,18.Atleast not on a sohc.Its more like 12,14,16 if im not mistaken.**** I wonder that about my car also,being a EJ8 I just did smog and it was at 12btdc ,I even wonder if that's correct?

Well i had it running at 16btdc and it was more responsive and felt like it had more power. I just set the timing to 12btdc and now it feels sluggish and lacking power.


i think you have your numbers mixed around
i thought it was suppose to be
18,16,14----------------0
not 12,14,16------------------0


This is where im confused at, i dont know if its suppose to be:
18,16,14--------------0
OR
12,14,16---------------0


because right now my timing is set at
18,16,14-+-----------0
The plus sign represents what my car is set at right now.
I have a y8 just for reference.

HONDACIVC93

its going to go in decreasing order what ever the numbers might be. otherwise you would be getting more degrees "before top dead center" as you actually get closer to tdc. ya heard?

HONDACIVC93

and i always thought sohc's had 12* btdc as base timing?

That's only some of them.

Ok thanks for the graph, but that still brings me back to the crank pulley.
Here is what it looks like on the pulley looking down on it
-------l l l------------------------l-------

Now is it
18-16-14------------------0-------?

Or is it
12-14-16--------------------0------?

I have the specs, i just need to know what degree the marks stand for on the pulley.
I have two different answers and i dont know which one it is.
I just reset the ignition timing to the middle mark out of the three on the crank pulley.

ddd4114

The red marking indicates base timing. I'm pretty sure that is the middle of the three markings.

For an engine that requires 16 degrees of base timing:
18-16-14----------------------------------0----------

For an engine that requires 12 degrees of base timing:
14-12-10----------------------------------0----------

Somebody correct me if I'm mistaken.

It's not going to count up to 0.

yes i know it doesnt count up to 0, nevertheless, if i have to have it at 12btdc i still need to know which mark is 12.
i just needed someone to clarify which mark was 12btdc.
But i think i have it right.

Thanks for clearing that up for me.

Sorry, didn't mean to insult your intelligence. I guess that was a typo. As already stated, BTDC is the middle tick and each tick on either side is 2* in all cases I've seen.

You can set your timing light to 12degree and line it up to the 0 mark.
