Wacker Neuson 5000162704 Main Jet #75

The Wacker Neuson Main Jet #75 is a genuine OEM carburetor component designed for GP2500A and GP3800A portable generators as well as the BFS735 gasoline powered floor saw. As a direct OEM part, the is manufactured to the exact specifications required by these machines, ensuring the carburetor meters fuel at the correct rate for consistent engine performance. This jet fits a broad range of GP and GV series generator variants — including standard, premium, value, and wheel kit configurations — making it a versatile service part for technicians maintaining multiple units in the field.

Key Features

• Calibrated #75 Orifice Size — the precisely sized #75 bore controls main fuel delivery through the carburetor, matching the fuel-to-air ratio the engine is tuned to run on.
• Genuine OEM Construction — sourced directly from Wacker Neuson, this jet is manufactured to the same specification as the original, so fuel flow characteristics are correct right out of the box.
• Drop-In Carburetor Fit — threads directly into the main jet port of the carburetor with no modification; compatible with standard jet removal and installation tooling.
• Broad GP and GV Series Coverage — fits GP2500A, GP3800A, GV2500A, and GV3800A generator variants across multiple build codes, plus the BFS735 gasoline floor saw.
• Restores Proper Engine Fueling — a worn, clogged, or incorrect main jet causes rough running, rich or lean conditions, and hard starting; replacing it with the correct #75 jet brings fueling back into specification.
• Fuel System Integrity — using the correct OEM-spec jet in a fuel delivery component helps maintain safe, stable combustion and prevents the erratic running that can result from an improperly sized or damaged jet.

The main jet is the primary metering component inside the carburetor responsible for controlling how much fuel enters the engine under load. It is a small brass fitting with a precisely drilled orifice — in this case sized at #75 — and even minor wear, varnish buildup, or physical damage to that orifice will alter the fuel mixture and degrade engine performance. On generators and floor saws alike, a compromised main jet typically shows up as surging, lack of power under load, excessive fuel consumption, or difficulty starting; replacing it with a correctly sized OEM jet like the Wacker Neuson 5000162704 is one of the most effective carburetor service steps available.
