Any variation of the definition "ping" comes from late model technology such as the" knock sensor" hence the related term "knock retard", or "spark knock".
Wrong....
"Spark knock" has been around since long before I got into this hobby. We commonly spoke of it in the 60s and 70s, and the term wasn't new then.
Here's a description of the 2 different mechanisms for "ping" or "spark knock" (the collision of multiple simultaneous combustion fronts), and "detonation" (spontaneous explosion of the mixture). http://en.wikipedia.org/wiki/Engine_knocking
I stand by my original distinction.
A bunch of arguing about this crap gives the original poster exactly ZERO benefit. I suggest sticking to the topic, instead of trying to display your great and glorious knowledge for all to see. There's a time and a place to argue, and people to argue with, and things to argue about; this is none of those.

Roughly paraphrased into modern English, and applied to figuring out what's wrong with your car:
The simplest explanation that fits all the facts is probably the right one.
I think it's more beneficial to post some valid info, rather than get all heated.
Just remember it was you that jumped on my post, and then replied with
incorrect information as if to discredit me. Why, I don't know because
my post is 100% correct.
As for your definition of detonation and Pre-ignition they are nothing alike.
Your link also provides nothing to support your original statement:
Knocking (also called detonation or spark knock, pinking in UK English or pinging in US English) in a spark-ignition internal combustion engines occurs when combustion of the air/fuel mixture in the cylinder starts off correctly in response to ignition by the spark plug,
As for carburetor tuning, don't be so foolish to type silly quotes at the
end of your post. You might want to check my background, schooling
and my experience.
Your link also does not contain any of the text you quoted; as least not on that
page. Please re-link your source.
Now the ball is in your court. I've asked you to clarify the points above
in your rebuttal as they are wrong.
I'm really not interested in arguing over some technicality that isn't germane to the issue at hand, or getting picked at by someone who doesn't have his facts straight and thinks that he has to force his particular "definitions" of miscellaneous unrelated terms on everyone, whether they matter to helping the OP get answers to HIS question, or not.
I'm sorry if you take having your technical erors pointed out to you so personally. At this point, it's pretty obvious to all, what the problem in this post has become.
I myself would prefer to abandon this pointless wrangling, and to return to helping the OP get his car running better.

As far as I'm aware, the OP has been given a few ideas and has tried them
to some success. There are others who are asking related questions which
we are all answering.
I do not feel you should sweep this under the rug so quickly. Your comments
about running vacuum advance and timing for TDC on the previous page are
completely false.
Maybe this is why people are having trouble tuning their motors...the false
information is left to stand. I don't agree with this.
Forget about the definitions. If you think Ping and Detonation are two difference
items, then have fun. If you think pre-ignition and ping are the same thing,
then you don't understand the terms.
If the OP could return with any more of his concerns, I'm sure several of
us could help out. I find you (Sofakingdom) to have quite a bit of facts
when it comes to carburetors, however I don't appreciate the attack on
semantics. You should have asked for a clarification (as I did) , or re-read
my post to see that the 'timed port' reference is correct.
Sorry to those who are bothered by this confrontation. Although my name
implies "trouble" I'm not here to start it.
