640350 640303 640271 Carburetor for Tecumseh LV195XA LV195EA LEV120 LEV100 LEV105 6.5HP 6.75HP Engine Carburetor for Toro 20016 20017 20018 22 Recycler Lawn Mower

What It Is

This is a complete aftermarket carburetor assembly designed to replace failing or clogged units on Tecumseh LV series engines (LV195XA, LV195EA, LEV120, LEV100, LEV105) commonly found on Toro 22" Recycler mowers (models 20016, 20017, 20018) and other equipment with 6.5–6.75 HP Tecumseh engines.

Fitment & Compatibility

• Engine series: Works with Tecumseh LV195XA, LV195EA, LEV120, LEV100, LEV105 (check engine tag under the mower deck or on the shroud).
• Toro models: Fits Toro 20016, 20017, 20018 22" Recycler models. Also fits many other Toro, MTD, Craftsman, and Yard Machines mowers using these Tecumseh engines.
• OEM cross-reference: Replaces OEM Tecumseh part numbers 640350, 640303, 640271 (and often 640347, 640348).
• Measurements: Inlet fitting is 5/16" barb for fuel line; mounting hole spacing is standard for these engines. Verify your air filter housing and throttle linkage match—some older models may need minor bracket adjustment.
• Note: This is an aftermarket unit, not OEM. It includes gaskets but may lack a primer bulb or fuel line—check your existing parts.

Key Things to Know

• Quality: Generally good for the price—metal body, brass jets, and adjustable float. Some users report needing to clean out machining debris before installation.
• Installation difficulty: Moderate (30–60 minutes). You’ll need basic tools (screwdrivers, pliers, possibly a small wrench). The hardest part is often aligning the throttle/governor linkage.
• Common gotcha: The supplied gaskets may be slightly thicker than OEM—use them, but torque bolts evenly to avoid air leaks. If the engine runs lean, adjust the idle mixture screw (if present) or check for debris in the main jet.
• Fuel system prep: Replace the fuel line and clean the fuel tank or filter before installing. Old varnish and debris will quickly clog a new carburetor.

Should You Buy It

If your Toro Recycler or similar Tecumseh-powered mower is hard-starting, surging, or won’t run at all due to a clogged carburetor, this is a cost-effective fix. It’s not for professional landscapers needing OEM durability, but for DIY homeowners, it reliably gets a mower running again for one to three seasons. Skip it if you’d rather rebuild the original carb (kit is cheaper but more work) or if your engine has other issues like low compression.
