Carburetor Compatible with Poulan Pro Lawn Mower PP19A42 (960460077 00) Replacement Carb

What It Is

This is a complete replacement carburetor for the Poulan Pro PP19A42 lawn mower (model 960460077 00). It mixes air and fuel for combustion, designed to replace a worn or clogged factory carb on 19 HP Briggs & Stratton engines.

Fitment & Compatibility

• Direct fit for Poulan Pro PP19A42 (model 960460077 00) only. Confirm your mower’s model number under the seat or on the frame.
• Engine compatibility: Briggs & Stratton 19 HP single-cylinder with a vertical shaft. Check your engine’s model/type/code (stamped on the valve cover or blower housing).
• OEM vs aftermarket: This is an aftermarket replacement, not a genuine Briggs part. Gaskets and fuel line size may vary slightly (typically 1/4” ID fuel line). Measure your old carb’s mounting bolt spacing and bowl diameter before ordering.
• Not universal: Will not fit other Poulan or non-Briggs engines without modification.

Key Things to Know

• Installation difficulty: Moderate. Requires removing the air filter, fuel line, and throttle linkage. A small screwdriver, pliers, and carb cleaner are useful. Expect 30–60 minutes.
• Common gotcha: The included gaskets may be thinner or thicker than OEM. If you get a vacuum leak, reuse the old gaskets or add a thin layer of gasket sealant.
• Quality: Most users report it works out of the box, but some need to adjust the idle mixture screw (if adjustable) or clean out machining debris. Flush it with carb cleaner before install.
• Does not include: Fuel line, clamps, air filter, or spark plug. You’ll need those separately if worn.

Should You Buy It

This is a solid budget fix if your PP19A42 won’t start, runs rough, or leaks fuel from the old carb. It’s cheaper than a full service and works for most DIYers, but expect minor tweaks. Not for you if you want OEM reliability or need a carb for a different engine.
