The Multiquip 1256244008 Main Jet EY40D is a genuine OEM carburetor jet designed for EY40D series equipment. As a factory-sourced component, this jet is manufactured to the exact specifications required to maintain correct fuel metering and engine performance. Fitment is confirmed for EY40D powered units, making it a direct replacement when the original jet is worn, clogged, or damaged. DHS Equipment supplies this part as an authorized Multiquip OEM replacement, so you can order with confidence knowing you are getting the right part.
Key Features
- Exact OEM Fuel Metering Spec — Manufactured to the precise orifice sizing required by the EY40D carburetor, ensuring correct air-fuel ratio is maintained at all throttle positions.
- Direct Carburetor Drop-In — Matches the original thread pitch and seat geometry of the EY40D carburetor bowl, installing exactly like the part it replaces.
- Confirmed EY40D Fitment — Sourced specifically for EY40D engine applications; use Multiquip part number 1256244008 to verify compatibility before ordering.
- Restores Full Engine Power — A correctly sized main jet delivers the fuel flow the engine needs at load; a worn or partially blocked jet causes rough running, power loss, and hard starting.
- Fuel System Integrity — Using a genuine OEM jet eliminates the risk of incorrect sizing that can cause lean-running conditions, which may lead to overheating and accelerated engine wear.
The main jet is a small but critical component inside the carburetor that controls the volume of fuel delivered to the engine under normal operating load. It works by metering fuel through a precisely sized orifice, and any deviation in that size — whether from wear, corrosion, or an incorrect replacement — will directly affect how the engine runs. A blocked or undersized jet causes the engine to run lean, resulting in power loss, overheating, and potential internal damage, while an oversized jet causes excessive fuel consumption and fouled spark plugs.
