What It Is

The Powtol 16100-Z8B-901 is an aftermarket carburetor designed to replace the OEM carb on Honda GCV160 engines, commonly found in push mowers and small tractors from Honda, Husqvarna, and Troy-Bilt. It’s a complete carb assembly (with gaskets) for mowers needing fuel delivery repair.

Fitment & Compatibility

• Engine check: This fits only Honda GCV160 engines (e.g., GCV160LAO S3B NH1, GCV160LA1 S3B, GCV160LA0 S3LB). Confirm your model number on the engine shroud—don’t rely on mower brand alone.
• Mower models: Compatible with Honda HRR2169VKA, HRR216K9VKAA, HRR216K10VKAA; Husqvarna 7021P, HU700F; Troy-Bilt TB240, TB130, 130XP. Check your mower’s engine, not just the deck.
• OEM cross-reference: Replaces Honda 16100-Z8B-901. This is an aftermarket part—not OEM, but uses the same bolt pattern and gaskets.
• Measurements: Verify the carburetor mounting flange (2-bolt pattern) and fuel inlet size (usually 5/16 in.). No special tools needed, but ensure your throttle cable and choke linkage match.

Key Things to Know

• Quality: Generally reliable for the price ($17.88), but some users report minor gasket fit issues—use the included gaskets or your OEM ones if they’re in good shape.
• Installation difficulty: Moderate. You’ll need to drain fuel, remove the air filter housing, and swap the carb. Expect 30–60 minutes if you’re handy with small engines.
• Common gotchas: The carb comes with no fuel line clamp—reuse your old one. Also, the idle mixture screw may be preset; adjust it (turn 1.5 turns out from lightly seated) if the engine runs rough.
• Warranty: No brand warranty beyond Amazon’s return policy—test immediately after install.

Should You Buy It

Yes, if your mower’s engine is a GCV160 and you want a budget-friendly fix for hard starting, stalling, or fuel leaks. It’s a solid value for DIYers, but if you prefer exact OEM fit or have a high-use commercial mower, stick with the Honda 16100-Z8B-901 ($40+).
