Briggs & Stratton 796258 Carburetor

Briggs & Stratton 796258 Carburetor meters the amount of fuel entering the engine while blending it with incoming air for combustion. It regulating the fuel-air mixture required for proper engine combustion during lawn mower operation.

Common symptoms include:

• Engine loses RPM while mowing.

• Engine starts only with repeated choking.

• Fuel delivery becomes inconsistent.

• Engine bogs down during acceleration.

• Carburetor develops varnish deposits.
