Membrane carburetor for petrol chainsaw TOR2525 (35) – replacement diaphragm YTOR25MG

Replacement membrane carburetor diaphragm designed for petrol chainsaw model TOR2525 (35). This spare part restores the diaphragm element that controls fuel metering and choke response in small two-stroke chainsaw engines. It is intended as a direct replacement when the original diaphragm is worn, cracked or otherwise compromised, helping to re-establish correct fuel flow and improve starting, idling stability and overall throttle response.

Advantages

The membrane is manufactured from durable elastomer material that resists fuel and oil exposure, helping to extend service life compared with a degraded original part. It provides consistent flex and sealing behavior to maintain accurate metering under varying engine vacuum conditions. The replacement part is compact and straightforward to fit, enabling efficient repair without the need to replace the entire carburetor assembly.

Suitable for

• Repairing TOR2525 (35) petrol chainsaws with a damaged or leaking carburetor diaphragm
• Restoring poor starting or irregular idling caused by diaphragm wear
• Routine maintenance to replace an aged diaphragm for reliable operation

Key specifications

• Type: carburetor diaphragm / membrane for two-stroke petrol chainsaw
• Material: fuel-resistant elastomer
• Function: controls fuel metering and choke diaphragm action
• Compatibility note: designed for use with TOR2525 (35) chainsaw carburetor assemblies
• Form factor: thin flexible diaphragm with mounting holes matching original carburetor

How to use

Ensure the engine is cool and the fuel supply is turned off or drained before starting work. Remove the chainsaw’s air filter housing and carburetor cover to access the old diaphragm. Carefully note the orientation and location of any gaskets and springs, then remove the worn diaphragm. Place the new membrane in the same orientation, ensuring a clean sealing surface and correct alignment of mounting holes. Reassemble components in reverse order, test for leaks and check idle and throttle response before normal operation.

Usage recommendations

Inspect the surrounding gasket and needle valve components when replacing the diaphragm; replacing those parts together can prevent recurring fuel leakage or poor metering. Use appropriate hand tools and avoid over-tightening screws to prevent deformation of the new membrane.
