I at LEAST had SOMETHING firing with the prior positioning. I followed the
recommendation of a good Spit mechanic on how to fix the problem, and it
seemed to sync up with some of the text in Haynes.
Now, help me out - I have trouble grasping the concept of a spark being 360
deg out of sync. Wouldn't 360 deg bring it right back to where it started?
The rotor goes counter clock-wise (CCW), with Haynes saying number 1 is at
11:00, 3 is at 7:00, 4 is at 5:00, and 2 is at about 1:00. The prior
arrangement was 2134. I'm confident that the diagram in Haynes showing the
spark wire configuration is correct (but thanks for mentioning it,
sometimes
it can be something silly).

Greg,
Spark plug location is totally arbitrary but MUST be coordinated with rotor
position. The factory, for consistancy sake, designated a particular hole
as #1 but the rotor must be positioned properly for this to work.
It sounds like the rotor is not pointing where it is supposed to. Try
this: manually rotate the engine (put in 4th and push car or some other
technique) until it is at TDC. The rotor should be pointing toward either
#1 or #4 spark plug. If it isn't then the distributor drive gear is not
installed right. To fix this it is necessary to remove the distributor and
the distributor pedistal and withdraw the gear and reinsert it.
Before doing this pull the valve cover and check which valves are
"rocking." If the valves for # 1 are "rocking" (exhaust closing and intake
opening) you are at TDC for #4. And vice versa. The slot on top of the
drive gear is offset a little bit and will allow the distributor to be
inserted one way only so pay attention to this.
The book shows this in better detail (with pictures) and requires that the
engine be turned to TDC on cylinder #1 and shows how to position the offset
slot. The gear is beveled and will turn as it is inserted so you have to
prewind it so that it is in proper position when fully installed. Do not
be afraid to make several attempts at it before you get it right.
Also, a 1/4-20 bolt (or 1/4-28, or 5/16-18 or something) will thread into
the gear and ease gear removal and insertion.
Good luck
Dave
