Multiquip 775 Main Hi Altitude Jet Ec07/10

The Multiquip 775 Main Hi Altitude Jet Ec07/10 is a genuine OEM carburetor jet designed for the RW1403HF roller. As a direct Multiquip OEM component, part 775 is manufactured to the exact fuel metering specification required for high-altitude operation, ensuring the engine receives the correct air-fuel mixture when working at elevation. Verify your model against the RW1403HF fitment before ordering to confirm this is the right jet for your application.

Key Features

• High-Altitude Fuel Metering: — Calibrated specifically for high-altitude operation, this jet corrects the air-fuel ratio to prevent rich running and power loss when the machine is used above standard elevation thresholds.
• Genuine OEM Specification: — Manufactured to Multiquip's exact orifice sizing for the Ec07/10 carburetor, so fuel flow rate matches the engine's designed operating parameters without guesswork.
• Direct Carburetor Fitment: — Designed to install directly into the Ec07/10 carburetor assembly on the RW1403HF, using the same thread pitch and seating geometry as the original component.
• Protects Engine Efficiency: — A correctly sized main jet keeps combustion clean and consistent, preventing fouled plugs, excess carbon buildup, and sluggish throttle response that a mismatched jet causes.
• Verified Multiquip Part Number: — Sold under the confirmed Multiquip OEM part number 775, eliminating the risk of receiving an incorrectly sized jet that can compromise carburetor performance.

The main jet is a small but critical component inside the carburetor that meters the volume of fuel delivered to the engine under normal running conditions. At higher altitudes, thinner air means a standard low-altitude jet will deliver too much fuel relative to available oxygen, causing the engine to run rich, lose power, and run roughly. The high-altitude version — such as the Multiquip 775 Main Hi Altitude Jet Ec07/10 — has a precisely sized orifice that compensates for the reduced air density, restoring the correct mixture and keeping the engine running cleanly. When this jet is worn, clogged, or the wrong specification for the operating altitude, the engine will exhibit poor throttle response, black exhaust smoke, and reduced compaction output.
