And if you don't have a dwell meter or feeler gauge (but the engine is running), here's a quote from the '67 Pontiac service manual:

"...If a dwell meter is not available, turn adjusting screw clockwise until engine starts to misfire, then turn adjusting screw one-half turn in the opposite direction to complete adjustment."

I always did the clockwise, miss, half turn back thing.. When I would put a dwell on it it was always perfect..

I'd look into rebuilding the original Carter AFB carb, that is an excellent carb..

Here's the remainder of what I was going to post before the computer decided to reboot on its own:

Purchasing the Pontiac service manual is one of the best investments you can make. You can purchase either new or used manuals on ebay, or order from:

Faxon
3901 Carter Avenue
Riverside, CA 92501
(800) 458-2734
http://www.faxonautolit.com/

Direct link the 66 manuals at Faxon:

Things are much simpler with a timing light, but a trial and error method of setting timing works good if you are careful.

Pontiac rotors turn counter-clockwise which is the opposite of Chevy. Sometimes this is forgotten which really confuses the process.

Turn the distributor clockwise to advance timing, and each advance should only be about a quarter inch movement of the circumference of the distributor at a time. Take the car out and road test it each time you move the distributor by rolling the throttle on and loading the engine. It's harder to hear detonation at higher RPM's so I prefer to load the engine in second gear and slowly go to the floor. Temporarily plugging the vacuum advance off and pulling the hot lead to the passing gear switch also makes the process easier. Keep advancing the timing until you can hear slight pinging. Then turn the distributor back 3/8" inch and you will be very very close to perfect. If you hear pinging again at any time, then pull another 1/4" back on the distributor.

Even with my digital dial-back timing light, I use the above method to find what my engine personally likes as far as timing. Every distributor is different, and small production changes in manufacturing engines results in each engine requiring a slightly different setting.

The nice thing about the timing light is you can record where your testing puts the initial timing, and you can set it back to exactly the same place after replacing points or moving the distributor. Pontiac says 6 initial advance, but the ideal setting can be 10, 12, 14 degrees initial advance for optimum performance and mileage.
