Advancing Timing? not sure
 

I want to advance the timing of my car. I think due to high miles i am losing compression. How do i advance the timing, and what other modifications are necessary besides running a higher octane fuel?

to advance the timing, jump the service connector, start the car and rotate the dizzy towards the firewall. and measure it using a timing gun 1-2 degrees is good enough.

2 questions, first how do i jump the service conector, and how do i rotate the dizzy, do i unbolt it?

u loosen the 3 bolts holding it to the head, then rotate, then tighten
