Carburetor for Husqvarna Z254 Z254F Z 248F Z248F 48" Zero Turn Mower 967638501

What It Is

This is a replacement carburetor for Husqvarna Z254, Z254F, Z248F, and Z248F zero-turn mowers with a 48" deck (model 967638501). It mixes fuel and air for combustion and is a direct-fit part for the 24hp Briggs & Stratton engine typically found on these mowers.

Fitment & Compatibility

• Check your mower model: Confirmed fit for Husqvarna Z254, Z254F, Z248F, and Z248F (48" deck). Verify your model number on the mower frame or owner’s manual.
• Engine specifics: This carb fits Briggs & Stratton engines with model numbers like 44P777, 44R877, or similar. Check your engine model tag (located near the spark plug or valve cover).
• OEM vs. Aftermarket: This is an aftermarket part, not genuine Husqvarna OEM. It may require minor adjustment (idle mixture screw) to match your engine’s fuel/air settings.
• Measurements: The carburetor mounting flange is 2.5" x 2.5" with a 1" intake bore. Fuel inlet is 1/4" barb. Verify these match your existing carb before purchase.

Key Things to Know

• Quality: Aftermarket carburetors sometimes have inconsistent casting or gaskets. Inspect for debris or rough edges before installation.
• Installation difficulty: Moderate. You’ll need basic tools (screwdrivers, socket set) and about 30-45 minutes. Expect to adjust the idle mixture screw (1.5 turns out from seated is a common baseline).
• Common gotchas: The included gaskets may be thin or misaligned—consider reusing your old gaskets if they’re in good shape. Also, the carburetor bowl drain screw can be tight; don’t overtighten.
• Fuel system prep: If your mower has old gas or varnish, clean the fuel tank and line before installing. A clogged fuel filter will cause poor performance with a new carb.

Should You Buy It

This is a good budget-friendly option if your original carb is worn (hard starting, surging, or flooding). It’s not OEM quality, but it works well for the price. Skip it if you want exact factory parts or if your engine has other issues (low compression, bad valve seals). For a quick fix on a working mower, it’s a solid value.
