The Multiquip 14586ZJ1800 Decomper Pin Holder Spring is a genuine OEM component designed for a wide range of Multiquip flat saws, Stow pavement saws, and compatible generators and welders including SP2, SP213H20, SP213H20A, CS8CE20H20, CS813H20, CS8CE13H20, CC8CE13H20, CC813H20, CS820H20, SP2SCE13H20, SP2SCE20H20, SP2S13H20, SP2S20H20, SP2S20H20A, SP2CE13H20, SGW-250SS, and GA-9.7 series equipment. As a genuine Multiquip OEM part, the part is sourced directly from the manufacturer to ensure correct fit and function with no guesswork. Keeping the decompression system operating properly is essential for reliable engine starting, and this spring is the precision component that makes it happen. DHS Equipment stocks this part and stands behind its authenticity.
Key Features
- Genuine OEM Decompression Spring Specification — Manufactured to exact tension and dimensional tolerances required by the decompression system, ensuring the pin engages and releases consistently with every pull of the starter cord.
- Direct Drop-In Installation — Engineered to seat correctly in the decomper pin holder assembly without alteration, maintaining proper spring preload and alignment upon reinstallation.
- Broad Fitment Across Flat and Pavement Saw Families — Compatible with SP2, SP213H20, SP213H20A, CS8CE20H20, CS813H20, CC8CE13H20, CC813H20, and additional Stow pavement saw and Street Pro flat saw models.
- Protects Engine Starting System — A fatigued or broken decomper spring causes hard starting, excessive starter cord load, and premature recoil wear; replacing it restores correct compression release and smooth engine crank.
- Fuel System and Starting Safety Compliance — Correct decompression spring tension is critical to safe, controlled engine starting on high-displacement saw engines; using the correct OEM spring avoids over- or under-release of cylinder pressure.
The decomper pin holder spring is a small but critical part of the engine's decompression system. During starting, the decompression mechanism temporarily vents cylinder pressure, reducing the effort needed to pull the starter cord through compression. This spring holds the decomper pin in its correct resting position and provides the return force needed to close the decompression port once the engine fires. When this spring loses tension or breaks entirely, the decompression valve may stay partially open, causing the engine to start hard, run poorly, or fail to build full compression — leading to poor cutting performance and unnecessary strain on the operator and starting components.
