New points .020 to .021, used .019. When you change setting the dewll will increase where it should be.

Timing: disconnect vac at carb and plug carb.
loosen bolt on back side of dist and set octane selector to (0) then retighten bolt. Loosen screw on front side of dist - that will then allow you to adjust timing. When you have the timing where you want it. Retighten the screw holding the dist. Shut off engine. Finally reset the octane selector to where it was if you remember(loosen bolt and turn dist). Set to somewhere 6-8 degrees. Each mark is 2 degrees- tighten bolt again ,you are done. The old books said to set octane selector to (0) before timing. They never told you to re set octane selector to where it was. The octane selector adds more vac advance.
