  • Turn on Both Fuel and Choke
  • DO NOT open the throttle (do NOT turn the throttle)
  • Move the starter down until it gets stiffer, your looking for top dead center
  • Let the starter come back up and give a full strong swift kick ALL the way thru
  • REPEAT (If necessary)
  • DO NOT KICK RAPIDLY
  • When warm just do not use the choke
