I have fire to the coil but not to the plug on a 1985 Honda four wheeler. Can you help me?
If you have fire to the coil but not out out of the coil, the coil is usually bad. However on mid 80's Hondas, there is another common, but little-known cause. The connector on the wire going to the spark coil gets loose, corroded or both. Pull the connector off and inspect the tab connector on the coil. This connection has to be the cleanest and best connection on your cycle. If the connector tab on the coil is not shiny, polish it with emery cloth and push the connector back on. If it is not the tightest connection on the Atv, squeeze the female connector so it makes a tighter fit when you push it on.
BTW in my experience, this is the leading cause of ignition failure on Hondas more than 20 years old with with CDI ignitions.
