How do I set/adjust the timing? on 1990 Ford F-250

I've got number 1 piston to the top, distributor arm is at number one spark plug, but the timing mark is still off. Engine is lacking power (too retarded). Any suggestions?

Unplug the SPOUT connector and set the timing to 10 degrees, Do this after the engine is warmed up and at a normal idle speed. The SPOUT connector is a little 2 wire black or gray connector that rests near the distributor. It disables the computer controlled timing so you can adjust it accurately.
