Components included in tool kit:
The main components of the kit include
various abrasive pads for cleaning gasket
surfaces, combustion chambers, valve seats,
and exhaust ports. A cylinder leak-down tester
is also included for checking exhaust and
intake valve sealing on all 4-stroke cycle
engines and also can be used to check piston
ring sealing and piston damage on all 2-stroke
cycle engines. Other useful tools are included

the tools included in the kit are also available
separately (see summary on page 9).
When performing a cylinder leak down test
the flywheel must be blocked at TDC (top
dead center) to avoid rotation of the
crankshaft as high pressure air is introduced
into the cylinder. When using on 4-stroke
cycle engines, the piston should be at TDC
on the compression stroke with both valves
closed.
To use the cylinder leak down tester on
STIHL 4-Stroke engines, remove the valve
cover and index the crankshaft as pictured
below. Verify that the piston is at TDC on the
compression stroke and both intake and
exhaust valves are closed.
