Issue with base timing. Can't line up the marks on the pulley
Long story short. Just put in a built 1.6 long block. Installed big nose crank with all the proper parts for the conversion. Car started right away and drives pretty well. Today i decided to make sure the base timing is right.
Took a timing light hooked up the spark plug sensor to the first spark plug and got power from the timing light power connector.
Set the fixed angle to 10 degrees in MSPnP.
Made sure i can see the mark on the pulley and cleaned it.
Turn the engine on, set idle at about 900 rpm.
Directed the light at the pulley and the mark is no where in sight
I did notice a little gouge on the pulley that was in one spot.
I turned the engine off and found the above gouge and it was about 90 degrees away from the mark.
What the hell is going on? I tried setting the trigger angle at 50 degrees and the car runs very good, at 60 it runs much worse and 55 is still pretty good.
I did carry over the CAM sensor from the old engine and set it at about the middle point.
When I set the first cylinder at TDC the mark on the pulley is not lining up with the T on the cover.
What am i doing wrong?

Before you do, perform a simple test:
Pull the #1 spark plug.
Drop the oil dipstick down the hole such that the tip rests on the piston face.
Rotate the crankshaft by hand in the direction of normal operation while observing both the crank pulley and the dipstick. The stick should reach its peak and start back down again just as the timing mark on the pulley crosses the "T" line.

I think that happened on my old car, but I had already set the timing so I never fixed it. My new car seems to have two timing marks, and with timing set at 10*, one lines up with the T and the other lines up with the 10. I don't understand, but it seems to work.
