You should check for spark from the wire not the plug. You could have a bad plug.
Just a thought.
Right... Hold the wire with a pair of rubber handled pliers close to a head bolt or something, and give it a spin make sure what ever you use has a good clean ground. More engine info would help, some of the Briggs twins had two coils... Coils are under the flywheel, sometimes a little surface rust on the magnets and/or the coils would reduce or stop ignition...
Not sure about twins, but the stator (alternator for charging the battery) is under the flywheel, the ignition armature is located under the cowl, next to the flywheel. It generates electricity by magnets embedded in the flywheel passing it, and sends that juice either to a coil, or directly to the plug (s).
I have a no spark issue. I pulled the plug and held it next to the manifold and got not spark.
Where/what is the coil on these?
Any other tests I can do myself before loading it up to go to the local small engine shop?
It cranks and eveything spins freely.
Thanks,

I have the 16 hp I/C Briggs (twin cyl) on my riding lawn mower.
Several years ago, I had been cutting grass (no problems with engine) and my wife called me in, for lunch. When I went back out, that engine wouldn't start for anything.
Bottom line. Bad ignition module.
Cost: About $60.
I changed it out, myself.
Here's what surprised me. One cylinder got spark. The other one didn't.
