My Briggs and Stratton 16hp twin cylinder industrial engine won't fire. I parked it last fall with a bad coil. Just replaced the coil the spark plugs and now it won't fire. It don't even act like it's firing. Any ideas???

Does it seem to have normal compression? If you have spark (at the correct TIME) and you've at least force-fed it some fuel, you should get SOMETHING. Just how much fuel did you dump in? If it was enough to completely wet the spark plug, consider it flooded. Try maybe a teaspoon full or less, or a squirt of ether and let us know what it does.

What were the symptoms last fall? Why the bad-coil diagnosis? Do you have good compression?

How did you determine that you had a bad coil? Are you sure you have the plug wires on the correctly?

If the magnets in the flywheel are rusty, clean them with sandpaper. It will make a difference.

I determined the bad coil because it would run for a min quite cool down repeat.

There is a little rust on the fly wheel. I'll clean it up
