Description

Overview:
This genuine Briggs & Stratton diaphragm-carburettor part (OEM 270026) is designed for older small engines with vertical crankshafts rated at 2-7 HP (1.5-5.2 kW). Made from durable, fuel‐resistant elastomer, the thin diaphragm controls fuel delivery within the carburettor, helping the engine maintain the correct fuel-air mixture across idle and load. It is commonly used in classic Briggs & Stratton Pulsa‐Jet and Vac‐Jet style carburettors fitted to many walk‐behind lawnmowers and other compact machinery. Replacing a worn diaphragm restores smooth starting, steady running and reliable throttle response, making it a practical maintenance item for tradespeople, groundskeepers and DIY users keeping legacy equipment in service.

Key Features:
- Genuine Briggs & Stratton OEM part for assured fit and specification (270026)
- Suited to older vertical shaft engines rated 2-7 HP (1.5-5.2 kW)
- Restores accurate fuel metering for cleaner running and easier starting
- Fuel‐resistant diaphragm material for long service life with modern petrol blends
- Direct replacement for the original component; no modifications required
- Helps stabilise idle and reduce hesitation under load
- Compact, gasket‐style form factor simplifies handling during refitting
- Suitable for routine DIY maintenance with basic hand tools

Typical Applications:
Used in older Briggs & Stratton powered equipment such as walk‐behind lawnmowers, lightweight rotary mowers, small generators, water pumps, plate compactors, and tillers. Ideal when engines struggle to prime, surge at idle, stall under load, or are hard to start after storage-common symptoms of a tired carburettor diaphragm.

Also known as:
Carburettor diaphragm, metering diaphragm, pump diaphragm, diaphragm gasket, fuel diaphragm, carb membrane, Pulsa‐Jet diaphragm, Vac‐Jet diaphragm.

Alternate Part Numbers:
