I currently have no spark on Cylinders #5 and #6 cylinders. I have visually inspected the Stator and flywheel. They look good, no loose magnets and the stator doesn't show any signs of melting. The motor reaches more than 300 rpm when starter is spinning. The power pack was replaces about 3 months ago. Some days I don't have spark on any cylinders. Today I have spark on all but #5 & 6. When I move the wire that goes from the power pack to the #3 coil to the #5 coil I have spark on the #5 cylinder. This should rule out bad coil. I have been struggling with this for a while. Any help would be appreciated.
