Need some timing carb help!
 

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

Pinging can be caused by a number of things but the most common cause is using too much advance for the fuel grade/compression ratio you normally use.

You want to read the mark that appears on the balancer at the index mark as the strobe hits it. To the left of center is advance and to the right is retard. I don't rememebr the spec right off but I think a fairly stock motor starts about 8 to 10 degrees of initial timing. (Look that up.. it's early and I'm tired!)

Your initial timing might be ok and you still have ping. That could be caused by having too large of an advance curve built into the distributor.
