I just swapped out a G14 engine that had a broken balance counter weight that went through the engine case with an older G2 engine that I had on hand. I changed over the electrical pulse pickup under the fly wheel and changed the coil, all other electrical connector plugged in well. Now when I go to start the engine I have no spark at the plug, I am getting 12 volts at the orange wire at the coil, also the engine will continue to turn over after the accelerator peddle is released and will continue turning after the ignition switch off for 5 to 15 seconds before it stops turning. What have I done wrong, or is the ignitor box gone bad? Thanks for the reply.
