Basic Tuning: HELP!

Sounds good. I noticed a bit of very minor leakage around the accelerator pump on the carb. Not to mention it has been sitting for quite some time and Im unsure if it has ever been rebuilt. Sounds like a project for this weekend! Time to clean off the bench again.

OK so, I have a question that may very well answer itself anyhow.

Will pinging (pre-igntion) < (that may be the answer here), be heard if the timing is too far retarded?
I ask this because if not, (just for ref) Ill back the timing off a bit more til' the pinging is completely gone. As of now it pings when under load or durring hard accleration.
Thoughts?
