MS026 Intake Manifold Sets – Intake Boot & Clamp Kit for STIHL 024, 026, MS240 & MS260
Essential Intake Boot Assembly for STIHL 026 & Compatible Chainsaws
This intake manifold set is a complete replacement solution for the rubber intake boot and retaining clamp on STIHL 024, 026, MS240, and MS260 chainsaws . The intake boot forms the critical sealed connection between the carburetor and the engine cylinder, channeling the air-fuel mixture directly into the combustion chamber . A loose or cracked boot allows unmetered air to enter the engine, causing a lean condition that manifests as hard starting, erratic idling, poor throttle response, or even engine seizure . Replacing the OEM part number 1121 141 2200 with this quality aftermarket boot and clamp restores the proper seal, ensuring reliable operation and consistent performance .
Technical Profiles & Materials
Critical Intake Seal – The rubber intake boot connects the carburetor to the cylinder, creating an airtight passage for the air-fuel mixture. A compromised seal is a common cause of hard starting and poor running on STIHL 026 saws . Replacing a cracked or loose boot resolves these issues without the need for expensive carburetor work .
Metal Sleeve Retainer – Inside the boot's throat is a metal spacer ring that maintains the shape of the opening where the boot attaches to the carburetor. This sleeve prevents the rubber from collapsing and ensures a consistent, leak-free seal at the carburetor interface . If this ring is missing, the seal can become distorted and leak .
Secure Clamp Fastening – The kit includes the correct retaining clamp to firmly secure the boot to the cylinder intake. A loose clamp is a frequently overlooked cause of air leaks that mimic carburetor problems . Tightening the clamp can sometimes solve starting issues without any parts replacement .
