Assy, Decompression Valve A014000110

This decompression valve is designed for professional-grade chainsaws to reduce cylinder pressure during starting, making pull starts smoother and easier on the operator. By momentarily relieving compression, it reduces strain on the starter mechanism and internal engine components, then automatically closes once the engine fires to restore full compression. Built from heat-resistant materials for durability under high temperatures and vibration, it’s a practical replacement for maintaining reliable starting and long-term engine protection.
