I do everything involved with the distributor by starting with aligning the timing marks to no. 1 cylinder. Check the position of the rotor, it should generally point to the 5:00 o'clock position. Disconnect the vacuum line. Pull the cap out of the way. Remove the hold down bolt and loosen the screw holding the advance to the list. shaft. Slide the list out. Remove the old advance unit. life the new one on. re insert the dist. in as close to the same position as possible. If the List. doesn't go all the way down, back it off and turn to rotor one way or the other to see if you can get it to easily slide in and retain the 5 O'clock alignment to the Distributor. body. This may take several tries. If all else fails, jog the engine until the shaft slides in and you have no.1 cylinder and the rotor aligned to No.1 cylinder at the 5 o'clock position. Install the bolt, align the octane lines to the center mark, tighten the screw but not complete yet , and install vacuum line. Static time the engine by hooking a test light to the Distributor side of the coil. turn on the ignition switch, adjust the distributor by turning it until the light just comes on. Lock it down. start the engine and use a timing light to get the final timing perfected. Insure to time the engine in accordance with the recommended RPM.
