Yes - set the contact point to the good value and then turn the engine to the spark mark.
Next put the rotor on top of the distributor shaft where it normally goes. Turn the rotor by hand as far as it will go. It will only turn one way. This is the advanced position. When you let go the advance springs will pull it back to where you started.
Hold the rotor in the advanced position and then set the ignition to begin opening points.
