I can't get my truck to stop with the ping ping ping pop.....

It runs alright but won't stop detenating.

I've never did timing on it myself before and need some help as to what I am looking for on the marks when the light goes off?

I have the carb rich because I thought the real lean mix was making it ping but know I think it is the timing but I have no clue now.....

Any ideas or tricks to this?

Cheers
