Koubliztic Z425 Carburetor Kit for John Deere D125 D130 Z245 — Complete Tune-Up with Fuel Pump & Spark Plugs

A complete Koubliztic carburetor kit that replaces OEM part 795967 and fits many John Deere lawn tractors and zero-turn mowers for reliable engine performance.

If your John Deere D125, D130, LA175, D170, LA145 or compatible model is running rough, hard to start, or showing poor throttle response, a worn or clogged carburetor and related components are often the cause. This Koubliztic Z425-compatible carburetor kit is designed to restore fuel delivery and ignition components in one package. It includes the carburetor itself plus a fuel pump, air filter, spark plugs and a range of seals and fittings so you can complete a thorough tune-up without hunting for separate parts.

Will this carburetor fit my specific John Deere model?

Yes — the kit is manufactured as a direct replacement for multiple John Deere part numbers and models. It’s a universal-fit replacement for a long list of 100-series lawn tractors and several EZtrak zero-turn mowers, covering common OEM references.

• Replaces part numbers: 795967, 796227, 796258, 796997, MIA11461, MIA11173, MIA11790.
• Compatible models include D125, D130, D140, D150, D170; LA135–LA175 series and X130R–X165 tractors.
• Also fits Z235, Z245, Z255, Z425 EZtrak zero-turn mowers and many listed chassis numbers.

What components are included and how do they help during a tune-up?

The kit bundles the core parts you typically replace when addressing fuel and ignition problems, so you replace worn elements at once and minimize return visits. These components restore clean fuel flow, proper air filtration and fresh ignition parts for improved starting and smoother running.

• 1 carburetor and 1 fuel pump to restore consistent fuel delivery.
• Air filter, fuel filters and gaskets to prevent contaminants from entering the engine.
• Spark plugs, fuel line, clips, shut-off valve and spin lock nuts to complete installation.

How difficult is installation and what should I prepare?

The kit is intended for DIY mechanics and small repair shops familiar with mower engine work. Basic hand tools and a clean workspace are required; you should allow time for fuel removal, part swaps and leak checks. If you’re not comfortable working with fuel systems, consider a professional install.

• Prepare common tools: wrenches, screwdrivers, pliers and a socket set.
• Drain or clamp the fuel line, then remove the old carburetor and related parts per your service manual.
• Use included gaskets and clips to ensure leak-free assembly; test run to verify proper idle and throttle response.

What performance or durability differences can I expect?

While individual results vary by engine condition, replacing an aging carburetor and worn consumables typically improves cold starts, idle stability and throttle transition. The kit is factory-tested and made from durable materials to provide a longer service life than heavily worn originals when installed correctly.

• Improved starting and smoother idle under normal operating conditions.
• Cleaner fuel and reduced clogging thanks to included filters and new gaskets.
• Components are tested for fit and function to reduce installation problems.

Who is this for: This Koubliztic Z425 carburetor kit is aimed at homeowners, landscapers and small repair shops that maintain John Deere 100-series tractors and compatible EZtrak zero-turn mowers. It’s ideal for anyone wanting a one-box overhaul of fuel and ignition components — especially when replacing a failing carburetor, addressing persistent starting issues, or performing preventive maintenance before a busy mowing season.
