Carburetor for Toro Recycler Model 20370 149cc Lawn Mower Kohler 6.75 Motor

What It Is

This is a replacement carburetor for the Toro Recycler 20370 lawn mower, specifically designed for the 149cc Kohler Courage 6.75 ft-lb engine. It mixes fuel and air for combustion, restoring starting and running performance when the original is clogged or worn.

Fitment & Compatibility

• Exact model match: Fits Toro Recycler model 20370 only. Verify your mower’s model number on the sticker under the seat or on the rear frame.
• Engine: Kohler 149cc (Courage 6.75 ft-lb) engine. Not for Briggs & Stratton or other Kohler variants.
• Deck size: Works with any deck size on the 20370 (typically 22-inch).
• OEM vs aftermarket: This is an aftermarket carburetor, not genuine Toro/Kohler. Aftermarket units often include gaskets and fuel line, but quality control varies.
• Check before buying: Confirm your mower’s model number is 20370 and engine is Kohler 149cc. Measure the old carburetor’s mounting bolt spacing (center-to-center) – should be ~50mm. Also verify the fuel line diameter (1/4-inch is common).

Key Things to Know

• Quality: Budget aftermarket – may need minor tuning (idle screw adjustment) out of the box. Some units have casting flash or debris inside; clean with compressed air or carb cleaner before install.
• Installation difficulty: Easy for DIYers with basic tools (screwdriver, pliers). Expect 20-30 minutes. Remove air filter, disconnect fuel line and governor linkage, unbolt old carb, reverse for new one.
• Common gotchas: Governor linkage is easy to misroute – take a photo before removal. The included gaskets may be thin; use OEM gaskets if possible to prevent vacuum leaks. Float level is pre-set but verify if engine floods.
• Return policy: Aftermarket parts often have limited returns. Test immediately after install.

Should You Buy It

Buy if your Toro 20370 won’t start or runs rough due to a clogged carb, and you want a fast, low-cost fix. Skip if you need OEM reliability for heavy commercial use, or if you’re not comfortable with minor tuning. For the price, it’s a solid gamble for DIY homeowners.
