Get the dampener slit on 15 BTDC. pop the dist cap & see if the rotor is on or very close to #1 or #6 plug wire. loosen clamp & turn housing CCW till the can is on the pass side in the ballpark where you want it with room to be turned back & forth either way so you can adj it. turn housing some more slightly (either way) till the magnet is lined up dead even with the nearest tooth. take the wires out of the cap. plug in the #1 or the #6 plug wire (whichever one the rotor was originally at/under) into the cap terminal above the rotor. route em CW starting with the #1 you just started with and go 8-4-3-6-5-7-2 or if you are starting with #6 then going CW plug in 5-7-2-1-8-4. Fire it up!
