Over the years I made a bunch of money un-fixing things that customers (who didn't know what they were doing) did to "fix" their machines. Bringing it to me in the first place would have cost them far less money then they ended-up having to spend to get it fixed correctly.
What engine is this?

Well, you ain't close to where I'm at, are you?
First identify what engine you have by the model number, then search for an electronic coil for that engine. I've done a few swaps from points and it's easy if you know what coil you need. If you want, send me the model #s from the engine and I can look it up for you.
After you take off the flywheel there is a stamped cover over the points held on with screws. The points are under it. The wire from the coil goes under the cover and it held between spring and the condenser to the points assembly. There are many you tube videos, watch one before you make an expensive mistake.

There is a small electronic add on available, that lets you use the original coil, and bypass the points and condenser.

Maybe an old 2.5-3.5 hp Briggs.
That cooling shroud came off of a different engine. Those numbers correspond to a vertical crankshaft engine. Horizontal crankshaft engines will have a 0-4 for the third digit (9 indicates a vertical crankshaft engine). Regardless, a B&S 398593 or 591420 Magnetron electronic ignition magneto should be the correct one for your engine. Use a standard thickness business card to set the flywheel clearance.
FYI, it would be much less expensive to just replace the points and condenser.

Ok, Thanks!
While I agree, I usually just replace them with the electronic coil. I have a few of these engines that are used very sparingly, and newer points seem to get corroded quicker with moisture than factory originals in my experience. Something like a Kohler K-series where the points are easily accessed on the outside of the engine is one thing, but having to keep pulling the flywheel when the engine loses spark is another.
Basically your small engine shop can order you a coil that will convert your motor to electronic ignition. That's all there is to it. No need to take off the flywheel; just install the new coil.
The Magnetron coil is a direct fit from a vertical shaft briggs lawn mower engine
Isn't there some wires you have to trim from the old points system behinds the fly wheel
