WitrynaA. Prior to removing the impulse coupling from the magneto, spin the impulse coupling in the direction of rotation stated on the magneto dataplate. B. The impulse coupling should engage the stop pin in the magneto below approximately 140 RPM. If the impulse coupling pawls slip past the stop pin or Witrynaduring starting. Verify the number of impulse couplings that are used for the particular magneto/engine installation. For those that use only one impulse coupling, verify that the non-impulse coupling magneto is grounded during starting. See following paragraph 2.
