All the '70's I know should have both advance and retard. I have a
'70 with both (CC53029, abut 5000 before yours). Note that one of the
connections is on the _bottom_ of the carb.

There should be 2 little tubes coming out of the front carb - one on
top, and one on the bottom, both on the engine side of the carb.
I suspect one of two things: a) entire engine replaced (what's the
engine #?) b) distributer (and maybe carbs) replaced (less likely).
The pieces of information need to figure this out are the engine
number and the carb numbers (the carbs usually have a little tag with the
carb number attached to one of the screws).

The carbs don't switch very well.... Actually, after figuring out
what engine and carbs you have, I'd advise setting the timing before looking
for deeper problems. The lack of retard shouldn't matter too much, and
I wouldn't expect it to cause pinging, or at least I wouldn't on my
car (my retard only does anything at idle, basically). But remember I have
a vacuum advance, so things may be different.
