timing

Here is what I did.
I advanced my initial timing until I started to hear the dreaded pinging. I then backed it off 3 degrees. I ended up with 16 initial. I then went into the dizzy and set my mechanical advance at 18 dgrees. That gave me a total of 34 degrees. I then changed my dizzy springs to have the total timing all in at 2500 rpm. This was on a MSD setup with no vacuum advance.
The first step is the most important as each engine will react differently to initial timing, some will like 10 degrees, others 20 degrees. It is the procedure that is important.
