Carburetor For Craftsman T100 T1600 LT2200 LTR2000 YTS3000 DYT4000 GS3500 YT3000 42-in Riding Mower Lawn Tractor Engine 500CC 14HP -21HP

What It Is

This is an aftermarket carburetor designed to replace the original on Craftsman riding mowers and lawn tractors equipped with 500cc engines in the 14HP to 21HP range. It delivers the fuel-air mixture to the engine and is a direct swap for the OEM unit on models like the T100, T1600, LT2200, LTR2000, YTS3000, DYT4000, GS3500, and YT3000 with 42-inch decks.

Fitment & Compatibility

Before buying, verify three things:

• Engine type: Must be a single-cylinder 500cc engine (common on 14HP–21HP Craftsman tractors). Check your engine’s model number (e.g., Briggs & Stratton or Kohler) – this carb is not universal.
• Deck size: Listed for 42-inch decks, but the carburetor itself is engine-specific, not deck-specific. Measure your engine’s mounting bolt pattern and inlet size.
• OEM vs aftermarket: This is a non-OEM part. It may lack the exact jets or gaskets of the original. Confirm your existing carburetor has the same number of mounting bolts (usually two) and the same fuel inlet orientation.

If your mower uses a different engine family (e.g., 20HP twin-cylinder), this will not fit.

Key Things to Know

• Quality variance: At this price point, expect thinner metal and possible burrs on the gasket surfaces. Inspect and clean before installation.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, disconnect fuel lines, and swap the carb. A new gasket is usually included, but check if yours matches.
• Tuning may be required: Aftermarket carbs often need idle and mixture adjustments. Be prepared to tweak the screws after installation.
• Common gotcha: The included fuel line or choke linkage may not align perfectly with your existing setup. Keep your original parts handy for reference.

Should You Buy It

This is a solid budget fix if your original carb is clogged or damaged and you’re comfortable with basic engine work and tuning. It’s not for someone expecting plug-and-play perfection – expect some fiddling. If you want a guaranteed no-hassle fit, buy an OEM replacement instead.
