Question and Answers


what should the gap be on engine model #143975038 between the flywheel and the coil


The air gap should be 12 thousandths. Once you have set the air gap check for spark. If you do not have spark remove the small kill sire from the coil, then check for spark. If you do not get spark the coil is bad. If you do get spark the there is a short in the kill wire. Follow the kill wire to the engine control. The wire should not have any bare spots touching the engine.
