Got this old 70's mower from a neighbor last week. Cleaned her carbs up and blew 12 years of leaves, fluff, and acorns out of the engine. Got a new spark plug but has no spark. I tried grounding the plug against the frame, got nothing. Thinking it might be the ignition coil because the cord coming off of the coil is pretty cut up. I want to order a new coil but I have no clue what to order. I've looked these model numbers up on the B&S website and I don't get much. Was hoping someone out there knew a thing or two about this "Wildcat" mower and could share their wisdom. Thanks.

FIGURED OUT MODEL #. 190702-0800-99 thanks StarTech!

So I got my ignition coil in, and the old one is out. I have a question about hooking up the ground wire. When I removed the original coil, a cord that was connected to under the flywheel was removed as well. Do I need to remove the flywheel and put this new cord in there, or can I splice it into the ground cord that I circled in the picture? I know one of the ground wires gets screwed right to the mounting point for the coil. I'm not sure how to remove the flywheel on this old dog, but if I have to I will. For now it is sitting in the shed with some Marvel Mystery Oil in the tank. Hoping I didn't screw myself by removing this old wire, thanks again!

Appears you got an after market points coil so yes the flywheel got to come off so you rewire the points to the coil connection.

Personally I would have went with the newer Magnetron coil and got away from the points and condenser system.

He should have asked on a Lawnmower Forum.

https://www.amazon.com/dp/B00MWOQZJC?psc=1&ref=ppx_yo2_dt_b_product_details This is the coil I ended up with. It seems to be similar to the one I had but it has this little extra "block" next to it. There's definitely a slight difference in appearance.

Comparison:

That's why I'm here. Hoping to be pointed in the right direction. I didn't even know you could upgrade these things that sounds like something I would like to do.

Yes that the point coil. Briggs actually no longer sell them but there are after markets out there. The Magnetron coil that replaces this is PN 398811 and there are lot of them in after market too.

The configuration looks like this. You will not need the points and condenser just the kill wire. You only need the points coil if you have a cast iron cylinder block. cast iron inner don't count as a cast iron cylinder block. Plenty of these Magnetron coils in the scrap piles as they the same one is use on the 7-16 hp engines. With 330000 in there up to 21 hp Intek engines.

I know. I was being sarcastic.
The Briggs engines had points until up to 1983 or so, and I always recommend putting the newer style coil on, and just clipping the wire to the points, and leaving the flywheel alone.
