My Grandfathers mower has a 392 Hemi with a Flamethrower magneto. He uses 8 lighting rods off his barn for plugs.

He must know that Granddad uses 16 lighting rods cause he has dual plug 392 heads on his mower. (I didn't want to tell Granddads speed mowing secret.) The other 8 lighting rods came from the house and corn crib and 1 came from the outhouse roof. (No more pooping during an electrical storm.)
