LT2000 YT3000 Carburetor Repl for Craftsman 42 inch YTS3000 LTR2000 LT1000 LT1500 DYT4000 GS3500 Riding Lawn Mower Parts, 14.5 21 HP Engine Carb Kit with Air Filter

What It Is

This carburetor replacement kit is designed for Craftsman riding lawn mowers, specifically models like the LT2000, YT3000, LTR2000, LT1000, LT1500, DYT4000, and GS3500. It includes the carburetor, air filter, and related components to restore fuel delivery and air intake on 14.5 to 21 HP engines.

Fitment & Compatibility

Before buying, verify your mower’s model number (typically on the frame under the seat or on the hood). This kit fits Craftsman 42-inch deck models (e.g., YTS3000, LTR2000) but also works with some 46-inch and 50-inch decks if the engine is a 14.5–21 HP Briggs & Stratton or similar single-cylinder. Check your engine’s make and displacement—most compatible engines are 500cc to 650cc. The carburetor is aftermarket, not OEM, so measure the mounting bolt spacing (typically 2.75 inches center-to-center) and fuel inlet diameter (usually 5/16 inch). Ensure your existing fuel line and throttle/choke cables match the kit’s fittings.

Key Things to Know

• Quality: Aftermarket carburetor; may need minor adjustment of idle and mixture screws. Air filter is generic but fits standard round housings.
• Installation Difficulty: Moderate—requires removing the old carb, cleaning the intake manifold, and reattaching cables. Expect 30–60 minutes.
• Common Gotchas: The kit may include extra gaskets not needed for your model. Use only the gaskets that match your carburetor base. Also, the float bowl may be plastic—handle carefully to avoid cracking.
• Performance: Improves starting and idling if the old carb was clogged. Not a performance upgrade—this is a direct replacement.

Should You Buy It

If your Craftsman riding mower with a 14.5–21 HP engine is hard to start, runs rough, or stalls under load, this kit is a cost-effective fix. It’s best for DIY owners comfortable with basic carburetor work and who want a complete kit (carb + filter) without buying OEM parts. Skip it if you need exact OEM fitment or have a different engine brand.
