Need some help. I have a 1999 big Bear 350 with no spark and am at a loss. I have replaced the ignition switch, stator, pick up coil, ignition coil, spark plug (double checked the gap), new battery, new plugs and pins off from the pick up coil and stator(old ones were not very good), and checked the wiring harness. Even tried a cdi box office from a running four wheeler and still didn't work. Everything else works (starter, lights, dash lights, winch). Just no spark.
