If you can assess the cells where you fill with water and if you have a volt meter connect your meter leads to shot pisces of wire to be thrown away later. Put the positive lead on the positive post of the battery. Put the wire connected to the negative lead in the water of the first cell nearest the positive post. On a twelve volt battery there your meter should show 2 volts. Each cell can be tested individually with this method. Just work your way from positive to negative until you reach the Negative post moving both leads as you go. Don't let your wires touch the plates in the battery
Just dip the wires in the battery acid a little bit. Thats all you need for a reading. If you find a cell that has less than 2 volts you have found a dead cell and that would cause your problem.

It takes six readings like that. I didn't no how else to show this.
I hope I explained it OK.I repeat don't stick the wires in too far. Hope this helps. PS this works best after charging the Battery. A dead cell wont accept a charge.

On most modern small engines the battery IS NOT necessary for the ingnition system to work. The battery has nothing to do with the ignition.

Most small engines are fitted with an armature type coil that generates its own power by way of flywheel magnets.

Think of it like this...pull start push mowers, weedeaters, chainsaws all have the same type ignition system as an electric start mower ride on mower.

Most mowers today are fitted with an electric fuel shutoff built in the carbuerator. They would not run without a power supply to this. The ignition would continue to work though.

The mower refered to in this thread being 24/25 yrs old may have a coil powered by an external source (battery) THESE are the type that wont run without a battery.

If your Craftsman tractor is about the mid seventies as you described it most likely has a Tecumseh with points or in a few cases an overhead valve Tecumseh with electronic trigger ignition.
If your battery tests Ok on a proper load tester and has no dead cells after testing with a hydrometer, you might want to trace your wiring with a voltage meter. On a lot of the older Craftsman tractors they used a heavy duty key switch as a starter solenoid. Remember also that your charging circuit also runs back through the key switch to the Postive side of the battery while the key is in the run position.
