Product Overview

A Stihl 4144-series tool that starts only with choke, stalls as the trigger opens, or will not hold idle may have stiff metering diaphragms or restricted passages after fuel lines, filter, tank vent, spark, exhaust screen, and air leaks are checked. This assembly replaces the matching C1M-S267-style carburetor.

Part 4144 120 0608 is not interchangeable with every similar-looking 4144 carburetor. Match the exact number, control levers, primer ports, and mounting details.
