Let me warn you. You may have created a monster. Below are pics of my son Christmas Day last year. He was eight then.

Now he thinks he needs a snowplow, fasthitch, disc and plow.

It never ends.

I have no idea, but I'd like to find out. Any thoughts on the best way to diagnose it?

There is some forum members who are specialists with the magneto. You could place a "Wanted" notice on the VINE, Classified. Another option is to take it to a CUBFEST where someone will be able to help you. It requires special tools to disassemble and overhaul. Also the ignition switch is different for a magneto.

Someone had mentioned there's a difference in the switches before. Do you know what the difference is?

Hi,
The ignition switch for a Battery Ignition unit has 2 posts on the back of it, it is connected to battery power. Battery power goes through the switch when it is in the on position.
The magneto ignition switch has 1 post on the back of it, it is not connected to battery power, the switch grounds the magneto when in the off position.

Here are pics from TM Tractor of the 2 different original style switches. They look about the same other than the number of posts. :)

Glen has you covered. Another way to say it is that the mag switch is designed to divert the flow of electricity from the mag to a more direct path to ground, thus stopping the engine. The battery ignition switch provides the path for electricity to flow from the battery to the coil.

Well we put the wheel weight back on the front right wheel and attached to the tractor last evening. I think I like the look of the silver carriage bolts. I think we will just clear coat them and leave them as is.

I have to agree with you. The silver rims both front and back do look really sharp. I plan to do that too, when I get around to painting.

Nice to see these repairs--you're doing a good job. Time spent with your son is valuable.

I would love to get the magneto working again. However, since the tractor is running the way it is i think I'll worry about the magneto after I get everything else fixed.

I don't disagree. What I've found more often than not is that people will go to an external coil when the original goes bad instead of replacing the original. It doesn't necessarily mean that the magneto itself is bad, just the coil.
New coils can be found from different suppliers ranging in price from $80-$100.
If you decide to eventually change it out, be careful when taking apart and reassembling the wires on the bottom stud. The insulators can be fragile. I ended up making my own out of thin rubber washers.
Why is there never enough time to do the job right, but always enough time to do it over. :?:

Hi,
Below is a listing from TM Tractor for a new magneto coil, you can see what it looks like.
There is a rectangular bar that goes through the center of it, you have to reuse the bar that you have.

http://www.tmtractor.com/new/el/713fp.htm

Here is a page from the Cub parts manual showing the magneto.
The bar is number 11 in the pic. :)
