OEM Nissan Carburetor Parts

Mix Fuel and Air with Carburetor Parts

Whether you're restoring a classic or fixing your own ride, Nissan Canada always has all the parts you need. Carburetor components include jets, floats, needles, gaskets, and diaphragms in older fuel systems. These precision parts meter fuel and mix it with air. Factory carburetor parts use specific dimensions that provide correct fuel metering. Proper operation ensures smooth running and good fuel economy.

How Carburetor Components Meter Fuel

Your carburetor uses air velocity to draw fuel through calibrated jets. The float chamber maintains constant fuel level using a float and needle valve. Jets control fuel flow at different throttle openings. Air bleeds mix air with fuel for proper atomization. Accelerator pumps provide extra fuel during rapid throttle opening. Choke mechanisms enrich mixture for cold starting. Nissan carburetor parts for classic vehicles use brass construction that resists corrosion. Idle circuits provide fuel at closed throttle. Main jets control high-speed fuel delivery. Power valves enrich mixture under load. Gaskets seal mating surfaces and prevent air leaks. The system integrates with fuel system components for complete delivery.

What Causes Carburetor Problems

Carburetor jets clog from dirt or varnish deposits in old fuel. Float needles wear and allow fuel to overflow. Diaphragms develop holes from age and chemical exposure. Gaskets shrink and create vacuum leaks. Throttle shafts wear and allow air bypass. Generic aftermarket kits use parts that don't match original specifications. Ethanol fuel damages some gasket materials. Accelerator pumps wear and deliver insufficient fuel. Internal passages corrode from moisture contamination. Float levels drift from bent float arms. Worn venturi surfaces affect air velocity calculations.

Rebuilding Carburetor Assemblies

Replace carburetor parts during rebuild intervals every 50,000 to 75,000 miles on older vehicles. Rough idle or stalling indicates metering problems. Most carbureted vehicles have been replaced by fuel injection. Clean all passages during rebuilds to remove varnish. Test float level after reassembly. Poor fuel economy suggests incorrect jetting. Hard starting when cold indicates choke problems. Flooding results from stuck float needles. Use proper rebuild kits matched to carburetor model. Genuine Nissan carburetor parts include correct jet sizes and quality diaphragm materials that restore proper function, unlike universal rebuild kits that may not include all necessary components or use inferior gaskets causing vacuum leaks.
