Spark Arrestor Screen
The spark arrestor is a fine mesh screen that captures carbon embers from the exhaust. Over time, carbonized oil deposits can completely occlude the mesh, creating excessive backpressure that prevents the engine from clearing exhaust gases at high velocities. This lack of scavenging causes the engine to 'choke' on its own exhaust when the throttle is opened, resulting in a bogging symptom.

Carburetor Repair Kit
At full throttle, the engine requires a significant increase in fuel volume to maintain combustion. This kit contains the metering diaphragm, which uses engine vacuum to pull fuel through the jets; if the diaphragm has hardened or lost elasticity due to ethanol exposure, it cannot deliver sufficient fuel for high-RPM operation, causing a lean-condition bog.

Fuel Tank Vent
The fuel tank vent allows atmospheric pressure to enter the tank as fuel is consumed. If the vent is clogged, a vacuum forms inside the fuel tank that physically restricts the carburetor's ability to draw fuel. This restriction is most noticeable at full throttle when fuel demand is at its peak, leading to immediate engine hesitation and stalling.
