Description
Overview:
This Impulse Hose is a Genuine Stihl part for high-performance chainsaws, including the MS 660 and 029. Made from tough, fuel- and oil-resistant rubber in a compact flexible form, it links the crankcase impulse port to the carburettor to carry pressure pulses. These pulses drive the carburettor diaphragm, helping maintain steady fuel delivery, smooth idle, and strong acceleration. As an OEM component (MPN: 1127 141 8600), it provides the correct fit and routing for your saw, supporting reliability and long service life. It is a straightforward replacement for a cracked, hardened, or leaking hose and is suitable for workshop maintenance or field repairs on a wide range of compatible Stihl models.
