Description
Overview:
This carburettor gasket is a Genuine Stihl part designed to seal the joint between the carburettor and the engine intake on a wide range of Stihl handheld machines, including BG45 and BG46 leaf blowers. Made from fuel- and oil‐resistant gasket material, it creates a reliable air‐ and fuel‐tight seal that helps maintain the correct air-fuel mixture, smooth idling, clean acceleration, and dependable starting. The precise cut-outs align with the carburettor ports and mounting screws for a proper fit. Supplied to OEM specification under part number 4140 129 0900, it is suitable for routine servicing, carburettor replacement, or rebuilds where the original seal has flattened, torn, or deteriorated.
Key Features:
- Genuine Stihl OEM gasket for assured compatibility and quality (Part No. 4140 129 0900)
- Fuel- and oil-resistant material for durable sealing performance
- Helps prevent air leaks and fuel seepage at the carburettor joint
- Maintains correct mixture and engine vacuum for smooth running
- Supports easier starting, stable idle, and consistent power
- Accurate cut and hole pattern for the listed Stihl models
- Simple to fit during carburettor service or replacement
- Suitable for professional maintenance and DIY repairs
- Cost-effective preventive part to cure erratic running caused by gasket failure
Typical Applications:
Used whenever the carburettor is removed for cleaning, diaphragm replacement, or tuning, and whenever an air leak is suspected. Common in routine services on blowers, brushcutters, hedge trimmers, pole pruners, Kombi engines, and MultiSystem units to restore a reliable seal between the carburettor and intake, improving starting, idle quality, throttle response, and fuel efficiency.
