Description
Overview:
This Carburettor Repair Kit is a non-genuine replacement for the RB77 set used on many Stihl two‐stroke chainsaws, including the 017 and 018. It is designed for Zama C1Q‐S57 and C1Q‐S43 carburettors. The kit contains the essential service parts typically required to restore correct fuel metering and pumping, such as precision gaskets, diaphragms and small hardware, made from a mix of rubber, composite and metal components. Fitting a fresh kit helps resolve hard starting, poor idle and hesitation under load by renewing worn, hardened or damaged carburettor internals. Suitable for regular maintenance or repair on machines used daily or seasonally, it offers a practical way to keep your Stihl MS 170 or MS 180 running reliably without replacing the entire carburettor.
Key Features:
- Non Genuine Part: quality aftermarket kit replacing RB77 for cost‐effective maintenance
- Compatible with Zama C1Q‐S57 and C1Q‐S43 carburettors used on popular Stihl models
- Includes the essential gaskets and diaphragms needed for a standard carburettor service
- Helps restore consistent starting, smooth idle, clean acceleration and full‐load performance
- Sized to match OEM specification for a proper seal and reliable fuel delivery
- Durable materials suited to typical chainsaw operating temperatures and fuels
- Straightforward to fit with basic hand tools, minimising downtime
- Useful for preventative servicing to reduce unexpected stoppages on site or at home
- A practical alternative to full carburettor replacement when the body is serviceable
- Supports routine tune‐ups after storage or when running quality has declined
Typical Applications:
Used to service and repair carburettors on Stihl chainsaws showing symptoms such as hard starting, surging, stalling at idle, bogging on throttle, or fuel leakage. Ideal for scheduled maintenance after long storage, when changing fuel type, or following heavy use in dusty conditions. Suitable for workshop overhauls or on‐site fixes to keep equipment productive.
