timing?

Put a light and vacuum gauge on it. Advance to the best vacuum, de-creasing idle, and adjusting idle mix screws, until tou get the best advance.

Shut it off, and re-start; sluggish/kick back; retard until it starts ok when hot. That's what it wants at initial. Then time to run it, check for ping. Couple degrees under ping; read total. Then play with total advance in dissy,

Gas will change, humidity and temp will change, needed timing will change, etc.
