What It Is

This is an aftermarket carburetor kit designed to replace the OEM carburetor on 190cc, 675-series engines found in popular push mowers like Craftsman, Troy-Bilt, and Toro 22 Recycler models. It’s a direct-fit replacement for engines that are hard-starting, surging, or running lean due to a clogged or failed carb.

Fitment & Compatibility

• Engine series: Only for 190cc, 6.25–6.75 HP engines in the 675 series (e.g., Briggs & Stratton 675EX, 725EX). Not for 625 series or non-675 engines.
• Brands & models: Craftsman, Troy-Bilt TB230, Toro 22 Recycler, and other mowers using that engine. Check your mower’s engine model number (stamped on the engine shroud), not the deck size.
• OEM cross-reference: Replaces OEM part numbers 799866, 790845, 799871, 796707, 794304. If your original carb is one of these, this kit fits.
• Measurements: The carburetor body is roughly 3.5” x 3” x 2.5”. The mounting flange and intake bore match the 675-series plastic intake manifold. Confirm your engine has a vertical shaft and a single-barrel float-style carburetor.
• Kit includes: Carburetor, gaskets, and often a fuel line filter. You may need to reuse your old choke linkage or throttle spring.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic hand tools (socket set, screwdriver) and about 30 minutes. Expect to remove the air filter housing, fuel line, and throttle cable. Watch a video for your specific model—linkage routing varies.
• Quality: It’s an aftermarket carb, not OEM. Most users report it works well out of the box, but a few need minor adjustment (idle screw or float height) to prevent flooding or lean running.
• Common gotchas:
  • The included gaskets may be slightly thicker than OEM—use a thin smear of gas-resistant sealant if you see a leak.
  • The fuel line fitting can be tight; warm the line in hot water to ease installation.
  • If your mower has a primer bulb, this kit may not include one—reuse your old bulb if it’s in good shape.
• Warranty: No manufacturer warranty; return policy depends on seller. Test fit before final assembly.

Should You Buy It

This kit is a solid, budget-friendly fix for a common 675-series carburetor failure. If your mower is hard to start or runs rough, and you’ve confirmed the engine model and OEM carb numbers match, it’s worth the $15. Avoid it if you need a perfect OEM fit or want a warranty—buy the genuine Briggs & Stratton carb instead.
