Help me understand my timing please

.hmmm I can't adjust my rotor phase like they illustrate in that video..:-k

This morning I was able to get it to idle down around 25 degress :blob:, BUT I had to turn in the main idle screw on the carb to bring up the rpm so it wouldnt die.

What should I be doing with the idle circuit while setting initial timing?

** bonus question :newb:

My old man gave me an older Sun Pro tune up kit, it contains the timing light, vacuum gauge and a tachometer, the tach has the same inductor hook up as the light. What is the right plug wire to put this on or does it matter? If its #1 can I run the tach and the light at the same time?

thanks guys!!
