These kits cover the small parts that wear out inside chainsaw carburettors, including gaskets, diaphragms, inlet needles, welch plugs and fuel lines, suited to Walbro, Zama, Tillotson and Teikei units fitted to Stihl, Husqvarna, McCulloch, Echo and Ryobi saws.

Match the kit to your carburettor model number (for example Walbro K24-WAT or Zama C1T-EL41A) rather than just the saw model, as several saws share the same carb. A rebuild kit is a cheaper way to fix rough idling, hard starting or poor power than replacing the whole carburettor.

Frequently asked questions

How do I know which kit fits my chainsaw?

Check the carburettor body for its model number, such as Walbro K24-WAT or Zama C1T-EL41A, and match the kit to that rather than the saw model, since different saws often share the same carburettor.

What's included in a gasket and diaphragm kit?

These kits include the gaskets and diaphragms needed to rebuild the carburettor, and often the welch plugs and seals that wear out with fuel residue and general use.

Why is my chainsaw hard to start or losing power?

This is often caused by worn diaphragms, gaskets or seals inside the carburettor affecting the air and fuel balance, which a rebuild kit is designed to fix.

Is rebuilding the carburettor cheaper than replacing it?

Yes, a rebuild kit lets you replace just the worn internal parts rather than buying a whole new carburettor, which is the more cost-effective option in most cases.
