Great job. There are a lot of great people on this site. We'd also like to see some pictures of your tractor if you can.
I am new to this type of thing. I am a mechanic or was. What is the blade connector on the new coil for? Where do you put the kill wire on the coil? I bought an MTD 990 with a 16hp Briggs that stopped running for the previous owner. The engine spins freely just needs spark.
