Products Application
Cold Starting Repair
The choke rod is critical for engaging the choke shutter when starting a cold engine . If this rod is bent, broken, or missing, the choke cannot close, making cold starting difficult or impossible.
Carburetor Service
When replacing or servicing the carburetor on Husqvarna 51 or 55 saws, the choke rod must be disconnected and reconnected. This small part is often damaged or lost during service and requires replacement.
Complete Tune-up Service
Comprehensive kits combine the choke rod with throttle rod, fuel filter, fuel line, air filter, and carburetor gasket, making routine servicing efficient and ensuring all standard maintenance components are renewed simultaneously .
