So I went the check timing on my 1.6, and wanted to confirm something.

I jump the TEN and GND pin and connect the timing light to Cyln 1. However, while I am aiming for 14 Degree, it seems the car runs quite rough at 14, and not sure if it would be stable at 10, however, if its advanced to 16, 18 or even slightly higher the idle smooths out quite a bit.

Once the jumper is removed, it idles ok and I have never had an issue with stalling, but a do get some dancing of the timing light/timing mark as well as the RPM's dance a little when i get it at 14 degrees. (two marks to the passenger side of the 10 degree mark)

I would check the crank pulley.

Specifically, whether or not the keyway is damaged somehow, allowing the pulley to rotate about the crank nose.

You can also check the timing belt marks, and see if everything lines up properly. That would tell you if your crank pulley is spot on, too.

The pulley itself can also be separated and your indicated timing could be off by quite a bit.

I checked timing gear this morning (see attached) and everything looks good there. Do you agree?

That does not show the pulley.
How about the timing mark on the pulley?

Let me reinstall the pulley, but from a brief inspection, everything LOOKS ok.

Please post a pic of the pulley without moving the engine.

The outer ring of the pulley with the marks moves versus the center when the bonded rubber ring between them gets old. That's what is wrong and why they are asking for reference pics.
