Measured another 903 fan today. Same measurements as mine. Checked the timeing. It appears to hav been about 6 degrees too far retarded.

To determine the correct timing marks, we removed the starter. Saw two marks highlighted in orange paint with degree indicators betwen them. I assumed the first line was TDC and the second was spark. We marked the damper and when the pointer was pointed to the spark line, and then out of aluminum made a pointer which we attached to a timing cover bolt.

Using a timing light and the mark on the damper, we were retarded about 6 degrees. Didn't have a chance to road test the car after we made the timing changes.

All the plugs looked in good shape.
