    Great work!
    Per the manual:
    Mount the governor (centrifugal advance) unit in it's housing. It can only fit one way as there is a notch in the back of the unit that must line up with locating pins. Next, screw the ring nut onto the camshaft end until tight and then use a punch and hammer to completely tighten the ring nut.
    No thread lock or torque value is spec'd.

    There I'm not JUST a smart ass.
    Your tool is a very good solution, from my hammer and punch work I can tell using a reasonable torque with that tool will resort in a better tight than awkward, angled, one spot hammering will give.

    Your advance assembly looks pretty dry. Did you lube the advance rod up good, pack the bushings in the ends of the cam full of grease? Also, the whole advance unit plate is just raw steel and can rust. I lightly coat the whole thing with oil. Not a lot, just enough to make it shine.

    fiftynineab, this is very interesting and so good to see happen.
    Approximately how many miles are on that engine ?
    The cam chain and mechanical advancer condition , lube, and adjustments may be key to your points setting. I actually enjoy the points setting challenges and believe once set according to timing light readings, your XS will be reliable !
    Big fan of keeping it stock here !

    The convertion back to stock continues. Can I use this coil or should I put the two separate original coils back on.

    I’ve installed a couple of Pamco’s and I know they couldn’t run with two single coils, they required a dual output coil such as that one. I’m gonna guess that the stock points set up will require two separate coils , the way it was originally set up from the factory.

    yup two coils or a double bump points cam. Mikesex used to have one but I didn't find it today when I looked.
    Never tried it but seems like I remember you could feed both sets of points to ONE dual tower coil.....

    well that answers that question two separate stock 40year-old coils.

    that works. Haven’t experienced a fail yet. Although I would encourage you to use new non resistant plug caps and wires.

    If I had my shop manual I could probably figure this out. And I've done a couple of Google image searches before asking. Lol where is the stock mounting location for the condenser. I realize I can mount it anywhere as long as it's grounded but thought it would be a good idea to put it back where it came from.

    Sweet! Brilliant idea using the form to find the answers you need. I'm taking notes and learning from my mistakes. Lol

    Thought on this wiring diagram? It looks good to me.

    Yes, that looks right. Original mounting location for the condenser "pack" was the back side of the left top motor mount. It's kinda hidden from view once mounted. There were also a couple wires, and orange one and a gray one, with double female bullet connectors on one end, a single on the other. One condenser wire along with the orange points wire plugged into the orange wire, other condenser wire and gray points wire plugged into the gray wire. Their single ends connected to the orange wires on the coils, orange to left coil, gray to right coil.

    Even if you could hook up your Pamco dual output coil, it wouldn't be the right resistance for points use. You need about 4 ohm coils for points. The Pamco coil is only probably 2.5 to 3 ohms. The points would burn up real fast using it.

    Thanks. Also
    1. is there a black ground wire coming off of the coil going to the Head?
    2. The two coil wires one from one coil one from the other they hook up to the red and white wires in the wiring harness?
