Put in 4th gear, push car forward to TDC
	Line up:  timing mark on camshaft is hole, pointer is metal coming off of engine
Turn distributor - CCW first some
Rotor pressed CW against shaft
Test light from ground to (-) on coil
Now move distributor CW until light comes on (points are open, so (-) isn't grounded)
Then need 4 more degrees - half turn of thumb adjustment screw (mark on side) in "A" direction
  (2 degrees on distributor is 4 degrees on crankshaft????)
  (5 clicks is probably 1 degree??)
  Greg says 3/8" from TDC is 4 degrees

ROAD TEST OPTION
----------------
I get the timing and idle about right in the driveway at home and 
take it out for a run on a quiet straight road (preferably a road
where you can safely pull onto the shoulder of the road). After
warming up (nice and hot), while in 4th gear I step on the gas at 
about 1000 RPM. The engine will either "lug" along or it will
accelerate with a pinging sound. If it's lugging, I safely pull off,
and set the vernier to be a bit more advanced. Then I pull back onto
the road and try it again.  I repeat this till I hear the engine
start to "pinging". Then I pull off again and set the vernier back a
bit towards retard.

If on the first run of the test drive, you accelerate and the engine 
is pinging at 1000 RPM, then start to re-set the vernier towards
retard a bit at a time till you can't hear the pinking anymore.

"pinging" is knocking/rattling/pre-igniting - sounds like tapping
a steel hammer against the side of the block.
"Lugging" is running too slow in too high of a gear
