As title said, trying to repair Briggs 4hp push behind -belonging to sister. Was not firing when I got it-must be coil-tried spinning flywheel-not even a tingle. Ordered new coil-same thing-ordered another one-still no spark. I am experienced lawn mower mechanic from years back before electronic ignition-just getting back in the biz & stumped already. The kill wire is disconnected from coil & all rust brushed off flywheel. This is model-10A902 type-2180B1. On the parts look-up list it shows two different coils: Part numbers793281 & 793352. The 793281 is the one I bought It mostly resembles the one on the mower. When I swapped out the new for new the parts man assured me this was the correct coil. So, are these both defective, the wrong coil, is there a mismatch between coil & flywheel?, I was assuming that there should be some spark even if wrong coil. Enlighten me please!
