Done with the 2N carb and...

Yes, that is how they work. All the key switch does is apply power to the coil so you will get spark to the plugs. Tractor should turn over with the key turned off. The later 9Ns and all the 2Ns had a mechanical safety that would prevent the starter switch from closing if the transmission was not in neutral.

To test this just measure the voltage on the battery side of the switch. Should be -6 volts if standard positive ground system. The starter side of the switch should show 0 volts. I would them remove the cable from the starter and while holding the voltmeter to the starter side of the starter switch have someone push the starter switch. If you get -6 volts on the starter side of the switch when you push the button chances are the starter switch is good. if you don't get anything when starter button is pushed either it is bad or the safety is keeping it from working. Take te two bolts out that hold the starter switch to the steering gear case and push the switch again and check the voltage at the starter side of the switch. If you still have nothing then the starter switch is bad. If the starter switch is bad you have the same problem that I have had. Finding a new switch. The proper switch is 9N-11450-B which I have not been able to find. I ended up getting a 9N-11450-A and brazing it to a plate with the correct bolt pattern. I think you could also mount it by just putting bigger washers on the bolts that hold it on.

Let us know how you come out.
