Drive Clutch Cable Adjustment    
Measure free play at the top of the lever, as shown. Free play should 
be 1/16 ~ 3/16 in (1 ~ 5 mm). If adjustment is necessary:
1. Loosen the lock nuts with a 10 mm wrench, and move the adjuster 

up or down as required.

2. Tighten the lock nuts and recheck free play.
3. Start the engine outdoors, and operate the drive clutch lever. 

Check that the drive clutch engages and releases properly.
If the drive clutch does not operate as it should, with correct cable 
adjustment, take the mower to an authorized Honda servicing 
dealer for repair.
