Wrong. Use the 1st notch as there is no BTDC with a mag, it must be TDC.

How to time a Magneto-Equipped Cub...film at 11:00
Whoever played with your Magneto did you no favours at all. But you can fix it and I would recommend that you do that. Yes, external coil will but it isn't a great fix. Been there, done that on a couple Cubs. I have found that putting the mag back to original sure helps in the future operation and maintenance of the Cub.
Example : 352355R91 New Farmall IH Magneto Winding Coil Cub & Cub Lo Boy C60 w/ J-4 Type
This one is on the tad expensive side, but they can be found on eBay for around $60.00 US.
251502R11 IH International Farmall Cub Cub LoBoy Magneto J4 Coil Cover w/ Gasket
You should be able to find a good used cap c/w the screws. You will have to make a gasket for it though.
This is the parts breakdown and you can see what it is you are missing. The most difficult part to find is the coil core -- that would be item# 11. Now, mind you, your mag is probably alright .. and would probably be a good candidate to bring back to original. Take you time and source the parts economically. The coil that I pointed to is ok .. it is an AI coil, not sure where it is made. Most of the time I recommend Mainely Magnetos as I have heard a lot of really good reviews about them. The other option is to find on eBay a complete magneto for a reasonable price. I was lucky and patient and found 2 different mags ... eventually paying less than $50.00 for each .. a lot less but I can't remember what the actual prices were. Just have to watch, be patient and ready to pounce when the time is right ... like 10 seconds before the auction end
You will have to decide which way to go, but experience has taught me that it is best to put things back the way that they were.
I know that this is a little bit late, but ..
