Briggs & Stratton Diaphragm - 270026

Product Details & Features

Keep your older Briggs & Stratton engine running smoothly with this genuine carburettor diaphragm (Part No. 270026) — a vital fuel‑system component designed specifically for older vertical‑crankshaft small engines rated approximately 2–7 HP. 

This authentic Briggs & Stratton diaphragm fits within the carburettor assembly and plays a crucial role in controlling fuel metering and delivery. Made from durable, fuel‑resistant elastomer, the diaphragm flexes to help draw fuel through the carburettor’s internal passages, ensuring the correct fuel‑air mixture for reliable starting, smooth idle and steady engine performance. 

Key Features:

• OEM Quality: Genuine Briggs & Stratton replacement, manufactured to match original performance and fit. 

• Precise Fuel Control: Works with the carburettor’s pump system to regulate fuel delivery for efficient combustion and steady throttle response. 

• Fuel‑Resistant Material: Made from durable elastomer designed to hold up against modern petrol blends and typical engine vibration. 

• Direct Replacement: Easy to fit into the existing carburettor without modifications on compatible older Briggs & Stratton small‑engine applications.

• Widely Used: Commonly found in classic walk‑behind lawnmowers, generators, water pumps and other compact outdoor power equipment with older Pulsa‑Jet/Vac‑Jet style carbs. 

Why It Matters:
A worn, stiff or torn diaphragm can lead to fuel starvation, hard starting, poor idle or hesitation under load. Replacing it with this genuine 270026 carburettor diaphragm helps restore correct fuel flow and dependable performance — a simple and cost‑effective way to keep your equipment running well.
