  STIHL Engine De-Carbonizer is a newly
  developed product for easily removing deposits of
  ash and carbon from the combustion chambers of
  mixture lubricated 2-stroke and 4-stroke cycle
  engines.
  Ash deposits or combustion residue are often the
  reason for a loss of compression and engine power.

Effectiveness is increased if the engine is warm.                     .   Let the fluid soak for one hour.
Wear safety glasses when handling de-carbonizer.
                                                                      Removing the fluid:

.   Set piston to TDC (on 4-stroke engines: TDC
    between exhaust and intake strokes – “valve
    overlap”).
