My situation was not just replacing the belt. I found my timing had actually jumped 30+ degrees when the timing belt ribs came off. So when I thought I was at TDC I actually wasn't.

The old belt was removed, I had the cam bar in place but once I removed the exhaust and installed the timing pin I was able to rotate the crank sprocket clockwise. You will know when you hit the pin. Anyway here's a pic of the 2 paint marks and the compass I put on the sprocket to show how far off it was.

I noted the number of teeth on the crank sprocket along with a 360* circle. As you can see each crank tooth is 18* of timing. Mine had jumped 2 teeth or 36* of timing.
