Carburetor for Toro 22 inch Recycler Lawn Mower XT675 XT650 Kohler 6.5Hp 6.75Hp engine

What It Is

This aftermarket carburetor replaces the fuel delivery system on Toro 22-inch Recycler mowers powered by Kohler XT675 or XT650 6.5–6.75 hp engines. It mixes air and fuel for combustion and is a direct swap when the original clogs or fails.

Fitment & Compatibility

Before buying, confirm these three things:

• Engine model: Must be Kohler XT675 or XT650 (check engine shroud or label near the spark plug). This carb does not fit Toro engines or other Kohler series.
• Deck size: Only for Toro 22-inch Recycler models (e.g., 20371, 20378). Measure your deck if unsure.
• OEM vs aftermarket: This is not a genuine Kohler or Toro part. It is a generic replacement. Verify the carburetor mounting hole spacing (approx. 2.5 inches center-to-center) and bowl diameter (about 2 inches) against your old unit. The included gaskets may be thin; keep your OEM gaskets as backups.

Key Things to Know

• Quality variance: Expect rougher casting and thinner gaskets than OEM. Some buyers report needing to clean out machining debris before installation.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, fuel line, and two bolts. A new fuel line (3/16 inch) is recommended if the old one is brittle.
• Common gotcha: The carburetor bowl screw may be soft metal—tighten gently to avoid stripping. Use thread sealant on the bowl screw to prevent leaks.
• Tuning required: You may need to adjust the idle mixture screw (usually 1.5 turns out from lightly seated) and the throttle cable linkage for smooth operation.

Should You Buy It

If your Toro 22-inch Recycler with a Kohler XT675/XT650 engine won’t start or runs poorly due to a clogged carb, this is a cheap fix. It’s ideal for DIYers comfortable with basic engine work and who don’t want to pay $50+ for an OEM carb. Skip it if you want a perfect fit or warranty support—buy the genuine Kohler part instead.
