Repairs How to repair or adjust my Honda lawn mower (propel lever) ?

This might be simple. On this Honda HRR2167VKA there's a central handle which when pushed downward propels the unit forward. Recently the lever handle has to be pushed much further in order to propel the unit, so far that it becomes perpendicular to the ground. Did the cable stretch ? Did the handle unit slip on the bar?

What to do to that it need not be depressed so much to operate ?

Thanks !
