Spark Arrestor Screen
This mesh screen located inside the muffler exit is the primary point of failure for power loss at high RPMs. Carbon deposits from the oil-fuel mix accumulate on the screen over time, creating a physical bottleneck that restricts exhaust flow. At full throttle, the engine's inability to purge exhaust gases results in an immediate loss of power or 'bogging' sensation.

Carburetor Assembly
If the exhaust is clear, the internal diaphragms of the carburetor have likely hardened or the internal fuel inlet screen is clogged. These components are responsible for metering the higher volume of fuel required at full throttle; if they fail, the engine runs lean at high speeds, leading to power loss or stalling.

Fuel System RePower Kit
This kit includes the fuel filter, air filter, and spark plug. A partially clogged fuel filter may allow enough fuel for idling and mid-range speeds but fail to provide the flow rate necessary for sustained full-throttle operation, causing the engine to starve for fuel when the trigger is fully depressed.
