A common problem among nitro newbies is that they yank the pull-starter cord too far and break the spring mechanism that pulls the cord back into the case. Quick short pulls are all that is required. Before you ever start your new nitro engine, pull the starter cord out about 8 inches or so. Use a red marker to mark the cord right where it exits the case, and then let it retract. Use this mark as a guide until you get a feel for how far to pull the cord.
