STIHL FS400 FS450 FS480 ZAMA Carburettor

The Gasket Genius carburettor for Stihl FS400, FS450 and FS480 brushcutters and clearing saws is manufactured to OEM specifications for correct fit and reliable fuel metering on this range of two-stroke garden power tools. Designed as a direct replacement, it restores proper air-fuel delivery, smooth throttle response and stable idle performance. This unit is compatible with the original Zama C1Q-S34H diaphragm carburettor pattern commonly fitted on these models, replacing standard Stihl carburettor part number 4128 120 0651 used across FS400, FS450 and FS480 machines.
