That sounds perfect for what you need and free, you will be surprized how good it will look with a little cleanup. Loosen the clamp on the carb it will come right out of the boot. Take the cover off unhook the throttle cable and unscrew the enricher plunger(choke cable) upper left black plastic piece on 3rd photo. Petcock screws may be rusted or corroded take care not to strip them when taking off.1 point

If carb is the only problem it would definately be worth fixing, the syrup means its been sitting for a very long time, i would clean up the fuel system tank and petcock of corse carb and go from there.1 point

You guys have great prices over there, and choices. Here batteries are two-hundred bucks, and even with the exchange rate that makes them dearer than they should be. It's freight, which has gone crazy since covid. I bought a starter bendix for an old inter bulldozer the other week, it was a good price at $33.oo American, but the freight, which once would have been twenty bucks kiwi, was $66.oo American.. My sixty kiwi buck part cost me over two-hundred kiwi bucks !1 point

It's all internal to the coil. The magnets induce a voltage in the primary windings, the voltage is allowed to flow through the windings as a current, in the old days through a set of points, now days through a transistor, then, back in the day, when the points opened and the current stopped flowing the voltage flowed into a capacitor to help prevent the points burning, but also to increase the counter flow of voltage that developed in the primary windings as the induced magnetic field collapsed. Now days a transistor stops conducting instead of points opening, and there may or may not be a capacitor in there(I don't know). The collapsing magnetic field, combined with the voltage getting reversed as it goes back out of the capacitor, causes a high voltage to be induced in the secondary windings and so a spark. The wire coming out is only a kill wire.. Some of your old bikes will have a long core with a winding that spans two of four magnets in the flywheel, and a set of points. That winding either powers a separate ignition coil up on the frame somewhere, or in old machines it powers a secondary winding that's wound right over the top of the first(primary) winding I described. The second way with the secondary wound over the primary right there inside the flywheel is mostly on stationary engines and the separate coil is more common on newer bikes, like the sixtes and seventies bikes. Real old bikes, with a villiers engine say, they used the old system too.1 point

And the spark is going through both spark plugs at every firing, one on each end of the secondary windings, so both plugs need to be connected or neither will spark.1 point
