How to acquire the Ignition Coil to Fire on a 16 HP Briggs
A 16 horsepower Briggs & Stratton engine which will not fire is probably the consequence of a faulty ignition armature coil. Most ignition armature coils cannot be repaired and must be replaced. In some instances, the timing may be off since the motor flywheel to ignition armature coil air-gap setting isn’t in the appropriate distance. Furthermore, dirt, debris, rust and corrosion around the flywheel magnets and ignition armature coil legs can give rise to a low-spark or no-spark condition which can be remedied by cleaning the ignition components thoroughly.
Disconnect the spark plug wires and remove the spark plug from the engine using a 5/8-inch spark plug socket and ratchet wrench. Double cylinder version engines have 2 spark plugs, one situated on both sides of the air filter. In single cylinder versions, the plug is either in the front or rear of the motor.
Unscrew the air filter housing cover retaining knobs and wing nuts. One cylinder engines have one knob and wing nut, while double cylinder engines have 2. Boost the air filter element from the air filter housing. Unscrew the air filter housing retaining screws using a screwdriver and remove the air filter housing from the motor assembly.
Unscrew the oil filler tube retaining screw in the blower housing with a socket wrench. Unscrew the blower housing retaining bolts from the motor assembly using a socket wrench. Lift the blower housing cover from the motor assembly to get the ignition armature coil.
Rotate the motor flywheel by hand until the motor flywheel magnet lines up with the ignition armature coil legs. Insert a .008 into .012-inch feeler gauge tool between the flywheel magnets and ignition armature coil legs to confirm the ignition armature coil air-gap. Utilize a .010 into .014-inch feeler gauge tool for motor versions with breaker point type ignition systems. If the air-gap is too large or too little the ignition armature coil will not receive the appropriate signal. If the air-gap setting is right, the ignition armature coil is bad and must be replaced with a brand new unit.
Adjust the ignition coil armature to motor flywheel air-gap for proper ignition armature coil fire, if needed. Unscrew and remove the retaining bolts from the ignition armature mounting studs using a socket wrench. Slide the ignition coil earth cable connector from the ignition armature maintaining bolt. Disconnect the halt switch cable connector from the ignition armature coil tab. Eliminate the ignition armature coil from the motor assembly.
Inspect the motor flywheel, flywheel magnets and ignition armature legs for debris, dirt,rust or corrosion and clean them using 220-grit sandpaper.
Catch the halt switch Landscaping design Phoenix, AZ cable connector onto the brand new ignition armature coil tab. Establish the newest ignition armature coil on the ignition armature coil mounting studs, against the flywheel magnet. Slide the ignition armature coil Landscaping design Littleton, CO cable connector onto among the ignition armature coil retaining bolts; insert the ignition armature maintaining bolts through the ignition armature coil legs. Pull the ignition armature coil backward from the flywheel and tighten the retaining bolts temporarily using a socket wrench.
Insert a .008 into .012-inch feeler gauge tool between the flywheel magnet and ignition armature coil legs, or a 0.10 into 0.14-inch feeler gauge instrument for breaker point ignition systems. Loosen the ignition armature coil retaining bolts. Catch the ignition armature coil legs against the feeler gauge instrument and flywheel magnets. Torque the ignition armature maintaining bolts to .25 inch pounds using a torque wrench and socket.
Reassemble the motor and start it several times to test for proper ignition armature coil fire. If the air-gap is set correctly, the motor should run smoothly without any misses or stutters.
