Description
Overview:
The Throttle Valve to Suit Amal Type 519 Carburettor (519/019) is a genuine vintage Amal part designed to restore precise throttle control on classic bikes and machinery running the Type 519 carburettor. The valve (often called the slide) is a close-tolerance component that meters the air-fuel mixture as the throttle opens and closes, helping to stabilise idle and improve pick-up. Made from durable, wear-resistant metal (typically machined brass), it is suited to period British applications, including many BSA machines that used the Amal 519. Supplied as unused old stock, it may show light tarnishing or storage marks, but remains functionally sound. Ideal for restoration and maintenance where originality and correct fit are required.
Key Features:
- Genuine Part: authentic Amal component for the Type 519 carburettor
- Correct geometry: maintains the intended cutaway profile and slide travel for reliable mixture control
- Durable construction: robust metal body designed for long service life under regular use
- Smooth operation: manufactured to close tolerances for consistent idle and throttle response
- Direct replacement: drop-in fit for Amal 519 with no modification required
- Restoration friendly: helps return vintage machines to factory-correct performance
- Unused old stock: may exhibit cosmetic tarnish from storage, with no impact on function
- Easy to fit: suitable for both professional workshops and competent DIY users with standard tools
Typical Applications:
Used in vintage motorcycles and classic machinery fitted with Amal Type 519 carburettors, including many British bikes and period industrial engines. Common in restoration projects where maintaining original carburettor operation and throttle feel is important, such as classic BSA models and heritage small plant.
