Compatible equipment / model
- Husqvarna 155BT backpack blower
- Husqvarna 165BT backpack blower
Product Overview
A backpack blower that starts and dies, bogs when the throttle is opened, or needs constant choke may have a fuel-metering problem after the filter, fuel lines, impulse path, and spark are checked. This carburetor replaces the complete metering body rather than relying on worn diaphragms or damaged adjustment circuits.
Match the primer, fuel nipples, throttle shaft, choke layout, and carburetor marking before installation. Small differences within the WYK family matter.

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Frequently Asked Questions
Q: What symptoms can a bad blower carburetor cause? A: Hard starting, bogging, fuel leakage, and an engine that runs only with choke are common, but cracked lines can act the same way.
Q: Are WYK-153 and WYK-317 machine models? A: No. They are carburetor references; the compatible blower models are Husqvarna 155BT and 165BT.
Q: Should I replace the fuel lines too? A: Replace any line that is stiff, cracked, soft, or loose on its fitting.
Q: Is tuning required? A: Final adjustment may be required for the individual engine and operating conditions.
