Wauebuly Carburetor Rebuild Kit for Johnson Evinrude Twin V4 & V6 439076 – Gaskets, Diaphragms, Needle Valves

Wauebuly 439076 is a complete carburetor rebuild kit designed to restore the fuel delivery and performance of Johnson/Evinrude Twin V4 and many V6 crossflow outboards.

This repair kit supplies the gaskets, seals, diaphragms and small parts needed to rebuild carburetors specified as 18-7046 (and equivalent 4-7046/439076) on a wide range of Johnson and Evinrude engines. It’s intended to revive throttle response, reduce leaks and return the carburetor to serviceable condition when original components have hardened, cracked or worn. Before ordering, check the engine model and year to confirm compatibility.

Which engines and years will this kit fit?

This kit covers many Johnson/Evinrude Twin V4 and V6 crossflow outboard applications across several decades. Fitment includes specific horsepower ratings and production years, so cross-reference your engine’s model number and serial range before purchase. Installation is only recommended if your carburetor matches the listed part numbers or visual components.

• V4 applications: select 1969–1979 and early 1980s models (multiple HP ratings)
• V6 crossflow: covers many 1976–1990 variants and specific higher-HP models
• Covers horsepower from 85 HP up through 235 HP depending on year
• Replacement for 18-7046, 4-7046 and labeled 439076 configurations

What parts are included and how do they improve the carburetor?

The package contains the common consumables used during a carburetor rebuild: gaskets, O-rings, needle valves, diaphragms and related hardware. Replacing those components removes air and fuel leaks caused by aged rubber and compressed gaskets, helping restore reliable fuel metering. The kit’s pieces match the layout shown in the primary product image to simplify identification during rebuild.

• Complete gasket sets for both carburetor bodies and float bowls
• New diaphragms and needle valves to renew fuel metering and sealing
• O-rings and small hardware to prevent vacuum and fuel leaks
• Parts arranged to correspond with the main reference photo

How difficult is installation and what tools will I need?

Installation is straightforward for anyone comfortable with basic mechanical work and carburetor service. Typical tasks include disassembly, cleaning passages, replacing kit components and reassembling with correct torque. If you’re unfamiliar with carburetor tuning or synching twin carbs, consult a service manual or a qualified mechanic.

• Basic hand tools: screwdrivers, wrenches and pliers
• Carburetor cleaner, compressed air and small brushes for cleaning
• Service manual for torque specs and synchronization procedure
• Optional: float level gauge and vacuum gauge for tuning

Will this kit fix every carburetor problem?

The kit replaces wear-prone seals and soft parts but won’t repair mechanically damaged bodies, warped components or severely clogged jets. If castings are cracked, throttle shafts worn or bore corrosion present, additional parts or a rebore/replacement carburetor may be necessary. Use this kit when the primary issue is degraded rubber, leaking gaskets or failing diaphragms.

• Effective for leaks, poor idling, and hesitation from aged soft parts
• Not a solution for cracked metal, damaged jets, or bent linkages
• Combine with a thorough cleaning for best results
