Husqvarna Carburetor 502845001 for 150BF/150BT/350BF/350BT – OEM Direct-Fit, Factory-Calibrated

Genuine Husqvarna 502845001 carburetor engineered as a direct OEM replacement for select Husqvarna 2-cycle backpack leaf blowers.

If your Husqvarna 150BF, 150BT, 350BF or 350BT is showing hard starts, rough idle, erratic throttle response, or heavy fuel consumption, the carburetor is a common wear item that affects engine performance. This is a brand-new, factory-original Husqvarna part built to the same specifications used on the equipment from the factory, so installation restores proper fuel metering and helps the unit run as intended when fitted correctly.

How does this replacement carburetor restore blower performance?

Replacing a worn or damaged carburetor returns correct fuel-to-air mixture control, which improves starting, idling and throttle response. Because this is an OEM part, dimensions, port locations and linkage align with factory components to reduce installation variances.

• Factory-calibrated jets and passages for correct mixture control
• Exact fitment designed for 150BF, 150BT, 350BF and 350BT models
• New diaphragms and gaskets where applicable to prevent air leaks
• Restores consistent throttle and smooth idle when installed properly

Will this carburetor fit my specific Husqvarna model?

This is part number 502845001, manufactured by Husqvarna for compatibility with specific models rather than universal application. Confirm your machine’s model number and cross-reference the OEM part number before ordering to ensure proper fitment.

• Direct fit for Husqvarna 150BF and 150BT backpack blowers
• Also fits Husqvarna 350BF and 350BT models
• Check your unit’s parts diagram or owner's manual for confirmation

What should I expect during installation and setup?

Installation is straightforward for someone familiar with small-engine maintenance, though it requires attention to gasket seating and linkage alignment. After mounting the carburetor, basic adjustments—idle speed and mixture—may be necessary for optimal operation according to the manufacturer’s specifications.

• Swap with the old unit using the same mounting points and linkages
• Replace any intake or primer gaskets to prevent vacuum leaks
• Perform recommended idle and mixture adjustments after install
• Wear gloves and follow safety steps for fuel-handling and engine service

How does choosing an OEM part benefit long-term reliability?

OEM components are manufactured to the original tolerances and materials that the equipment was designed with, reducing the risk of fitment issues or premature failure. Using the genuine Husqvarna carburetor helps maintain the machine’s spec'd performance and simplifies future servicing because parts match factory diagrams.

• Exact match to factory dimensions and performance standards

• Streamlines repairs, diagnostics, and parts ordering later on
