IntelliCarb™ Compensating Carburetor The IntelliCarb™ Compensating Carburetor measures the air pressure on the clean side of the air filter and adjusts the metering diaphragm in the carburetor. This keeps the RPM at a consistent level, even when the air filter begins to clog.
Simplified Starting Procedure To get started, simply pump the fuel primer, set the choke and pull the starter cord. The built-in stop switch allows the user to turn off the engine with a simple press of the button. When the engine is off, the throttle lock automatically returns to the “start” setting. Your power tool will be ready to be started when you’re ready to get back to work.
