the solenoid only works as a switch so that should not be the problem. Aside from the coil there is a condenser usually mounted to the side of the distributor. Seldom goes bad but if it does it will not work. To hot wire it a wire from the plus side of the coil to the plus of the battery should make it start. I am not sure where the minus side is supposed to go... possibly the distributor.

It is shovel in a sand box simple. Don't over think it.
