ROCKER ARM CLEARANCE
The rocker arm clearance may need adjustment if your
unit suffers a loss of performance power or has trouble
starting. Adjusting the rocker arm clearance requires
disassembly of the engine. If you feel unsure or
unqualified to perform this, take the unit to a Sears or
other qualified service dealer.
NOTE: Inspect the valve to rocker arm clearance with a
feeler gauge after the first 10 hours of operation
and then every 25 hours of operation thereafter.
• The engine must be cold when checking or adjusting
the valve clearance.
• This task should be performed inside, in a clean,
dust free area.
To adjust the rocker arm clearance:
1. Remove the two (2) screws on top of the engine cover
with a Flat-head or T-25 Torx screwdriver (Fig. 25).
