Default cam timing

manuals don't say specifically so I just wanted to check... cams are timed with the front cylinder timing mark in the window?

Doesn't matter, line up with the mark on the pinion gear.

I was hoping to say nevermind before someone posted. Allready figured out and back together. Sometimes I impress myself, other times I have to ask myself "WTF were you thinking". This time was the latter. Thanks for the swift response though.

Feel free to charge for your information if you like, but to do cam timing you are not required to align the timing mark dead center in the hole.
That is done when you want to time the oil pump breather.
But then, I am sure you know that........pg

Yep, when you have had an engine apart, or at least had the oil pump removed, the first thing you do is:
Insert the pump.
Then move the flywheel to show the mark in the hole. This positions the crank in the position you need to obtain proper timing of the pump breather.
Next is to make sure the small hole in the breather tube lines up with the notch. Now we are finished timing the breather.

After that, the timing mark is ignored. In fact it moves away from the hole when you do the next step.....which is timing the cams to the pinion gear.

I guess the timing mark exercise is better stated as the step to set the breather timing correct before you move on to the cam timing. Of course that is done by lining up the mark on the pinion mark with the cam closest to it and then the other cams follow.
Lining up the pinion mark requires moving the flywheel.... and I find some people become confused because they think the timing mark has to stay at the hole when you time cams. Timing mark in the hole is just not part of timing the cams, it is for timing the breather..........pg

Yes right (as usual) , if you have removed pinion gear from crank notice that you can put it back correct way. It can be installed at least 2 ways and only one is correct.
Affe has done some research about timing breather:

Default Cam timing.

That mark is only for setting the points.
