I am presuming you have TESTED for spark, by removing the spark plug, gorunding it against the engine and pulling on the pull rope. If no spark is present (should be a nice, blue color); then I would check the armature air-gap. This is the distance between the magnets inside the flywheel in relation to the pickup legs on the ignition coil module. OHV Briggs engines typically specify the gap being between .006" and .020". A standard sized business card is also a good gauge to use. Remove the engine cover and turn the flywheel until the magnets in the wheel line up with the coil. See if you can slide a business card into the gap..if you can't...you will have to loosen the screws on the coil and adjust until you can. The slots for the screws in the coil are elongated for this purpose. I just double the card over and let the magnets pull the coil legs against it and tighten it at that point. A steel feeler gauge causes problems because it "sticks" to the magnets on the flywheel, confusing the "clearance" setting. Try these solutions and post back if needed.
