Carburetor Carb 794572 Replacement for Craftsman LT1000 LT2000 DLS3500 14HP 15HP 16HP 17HP 17.5HP 18HP 20HP Engine Parts

What It Is

This is a complete carburetor replacement for Craftsman LT1000, LT2000, and DLS3500 lawn tractors, designed for engines from 14HP to 20HP. It regulates the air-fuel mixture to keep your engine running smoothly.

Fitment & Compatibility

Before buying, verify three things: your engine’s horsepower (14–20HP range), engine brand (typically Briggs & Stratton or Kohler), and the OEM part number 794572 stamped on your old carburetor. This aftermarket part replaces OEM 794572 and fits most Craftsman tractors with 42-inch or 46-inch decks, but measure the mounting bolt spacing (typically 2.5 inches center-to-center) and fuel inlet size (usually 1/4-inch barb) to confirm. It does not fit zero-turn mowers or engines under 14HP.

Key Things to Know

• Quality: At $16.98, this is a budget aftermarket part. Expect minor casting imperfections or gasket misalignment; you may need to clean out debris or adjust the float height.
• Installation: Moderate difficulty—requires removing the old carb, transferring the throttle linkage and spring, and re-attaching fuel lines. Watch for a missing gasket; buy a separate gasket kit if not included.
• Common gotchas: The included bolts may be too long or too short—keep your original hardware. Also, the choke linkage might need bending to match your mower’s cable.
• Tuning: After install, you’ll likely need to adjust the idle and mixture screws (if present) to prevent surging or stalling.

Should You Buy It

Buy this if you have a Craftsman LT1000, LT2000, or DLS3500 with a 14–20HP engine, and you want a cheap fix for a clogged or failing carburetor. It’s ideal for DIYers who can handle basic engine work and don’t mind minor tweaks. Skip it if you need a perfect OEM fit or have a non-Craftsman mower.
