Description
Overview:
This Metering Diaphragm is a Genuine ECHO carburettor component designed to control fuel delivery to the engine for stable idling, smooth acceleration and consistent cutting performance. Manufactured to OEM specification (MPN P005003190), it uses a fuel‑resistant diaphragm material and precision venting to maintain the correct pressure in the metering chamber. It is intended for ECHO two‑stroke machines, especially compact professional chainsaws such as the CS-362TES and CS-360TES, where reliable fuel regulation is essential. Replacing a worn or stiff diaphragm restores proper metering, helping to prevent hard starting, lean running, surging and poor throttle response. Built for regular use in demanding environments, this genuine part supports long service life and dependable operation when fitted and tuned according to the machine’s service guidelines.
Key Features:
- Genuine ECHO OEM part for assured fit and performance (P005003190)
- Fuel‑resistant diaphragm material for durability with modern petrol blends
- Maintains correct carburettor metering pressure for clean running and power
- Helps cure symptoms such as erratic idle, hesitation and flat spots
- Direct replacement with no modifications required
- Supports reliable hot and cold starting in two‑stroke engines
- Suitable for professional and domestic use in compatible ECHO chainsaws
- Compact, lightweight component for quick routine maintenance
