Attention X-Torq versions

Important note: this carburetor is not suitable for all X-Torq versions. Before purchasing, always check the original code, the shape of the carburetor fitted to your chainsaw and the position of the connections.

To avoid mistakes, we recommend not relying solely on the chainsaw model, but also comparing the original carburetor and any codes marked on the old spare part.

When should you replace the carburetor?

• The chainsaw is difficult to start
• The engine does not maintain idle speed
• The machine stalls when you accelerate
• The carburetor can no longer be correctly adjusted
• The original carburetor is damaged, dirty, or worn
• The chainsaw loses power during cutting

Checks before purchasing

Before purchasing, always compare the carburetor with the original one fitted to the chainsaw. Some Husqvarna and Jonsered chainsaws may be fitted with different carburetors depending on the year, version, or machine configuration.

• Check the original code 503281805 / 503 28 18-05
• Check if the old carburetor is marked Walbro HD-12, HD-12B or HD-12C
• Compare the shape, dimensions and connections of the carburetor
• Check the position of the adjustment screws
• Check the connections of the fuel lines and primer, if present
• Carefully compare the product photos before ordering

If in doubt: contact us before purchasing by sending the brand, chainsaw model and photos of the original carburetor. We will help you verify the correct compatibility.
