    Pretty confusing as he is using different advance units from different bikes it would appear.

    For all the CB/CL 350's I've worked on the 286 stamp is on the left side, the direction arrow on the right and the notch on the points cam is also on the right at about the 4 o'clock position.

    my advance is stamped 286 and has a notch on the cam that is 180 degrees off the key slot on the back side. according to this video...mine is wrong.

    Best way to check it is to put the advancer back on the camshaft correctly, take the valve covers off the left cylinder, turn the engine over at the alternator rotor and watch to see if the points open at LF after the intake valve opens and then closes... if they do not, and the points don't open until 180° later on the camshaft, you'll need to pull the breaker cam (the lobe that opens the points) off the advancer and turn it 180°. If you've had the advancer apart to service it, it's easy to get the breaker cam back on 180° out

    Tutorial is wrong.

    Mark on points cam on the front of the advance unit is 180 degrees from the slot for the engine cam pin on the back of the advance cam unit.

    If your bike ran with the advance they way you said - it is right.
    If it is 180 Out it will NOT run. - PERIOD - Will not RUN.
