Often overlooked until it fails, the carburetor is the <em>engine\u2019s breathing and fuel delivery system<\/em>.

In a four\u2011stroke gasoline engine, fuel enters the intake manifold, mixes with air in precise proportion, and burns during the power stroke. When this mixture is correct, combustion efficiency peaks near the ideal Air\u2013Fuel Ratio (AFR) of <strong>14.7:1<\/strong> for gasoline engines \u2014 meaning 14.7 parts air to 1 part fuel by mass.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"why-air-fuel-ratio-matters\">Why Air\u2013Fuel Ratio Matters<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Lean mixtures (too much air):<\/strong> Can cause knocking, overheating, and poor throttle response.<\/li>\n\n\n\n<li><strong>Rich mixtures (too much fuel):<\/strong> Lead to black smoke, fouled spark plugs, and deposit buildup.<\/li>\n\n\n\n<li><strong>Optimal AFR:<\/strong> Improves power, reduces emissions, and extends component life.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"carburetor-types-used-in-lawn-mowers-and-farm-equipment\">Carburetor Types Used in Lawn Mowers and Farm Equipment<\/h2>\n\n\n\n<p>To choose the <em>B\u1ed9 ch\u1ebf h\u00f2a kh\u00ed t\u1ed1t nh\u1ea5t<\/em>, you must understand how each type functions:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"float-type-carburetors-most-common-for-horizontal-engines\">Float\u2011Type Carburetors \u2014 Most Common for Horizontal Engines<\/h3>\n\n\n\n<p>Float\u2011type carburetors maintain a consistent fuel level using a float bowl, similar to a toilet tank.
