Description
Overview:
This genuine Makita insulator (OEM No. 421950-0) is a small but vital component for the Makita DCS230T chainsaw. It sits between the carburettor and the cylinder, helping to seal the intake path and reduce heat transfer from the engine to the carburettor. By limiting heat soak and air leaks, it supports stable idle, smooth acceleration, and consistent cutting performance. The part is made from a heat-resistant polymer/composite for long service life in tough outdoor conditions. Engineered to Makita specifications, it fits the DCS230T precisely and replaces worn, cracked, or warped insulators that can cause poor running and hard starting. Genuine Makita quality ensures correct alignment and a reliable seal without modification, making it suitable for routine maintenance or repair.
