The self-propeller cable on my Honda Harmony HRM215 mower recently snapped, so I went to the local Honda repair shop to get a new cable. I'm not sure how the cable attaches to the lever under the mower. The end of the cable appears to be too large to "snake" through the housing chamber. Also, the lever underneath is very difficult to move, even with bare hands. Any tips on how to change out this cable and if there might be any hint of problems with the clutch mechanism would be greatly appreciated!
