This is the one for most older 9 - 11 cubic inch motors. Has extra parts to replace points in the old motors, works to replace newer magnetron system coils/armatures. Great deal here on eBay for this particular one, pays to shop a while. Usually over a hundred thousand B&S parts listings, sure makes for a handy source these days.
This coil was not exactly compatible with mower, although it was supposed to be. It started fine, but ran too fast. It would not idle down until I trimmed a piece of the governor vein off. The coil interfered with the vein.
