IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.\u003c\/div\u003e\n\u003c\/article\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"acco acco--standard  acco--open  acco--transition-ended\"\u003e\n\u003cdiv class=\"acco__content\" data-test-id=\"accordion-content\"\u003e\n\u003cdiv class=\"acco__inner\" id=\"acco-section-535\" role=\"region\" aria-labelledby=\"acco-button-535\"\u003e\n\u003carticle class=\"m_product-features__accordions__content\"\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe Master Control Lever™ is an easy to use single lever, operating the choke, starting throttle lock, and on-off switch.
