Description
Overview:
The Carburettor Throttle Spring for the JAP Model 3 Industrial Engine is a small but essential component that keeps the throttle returning smoothly to the correct position after actuation. Made from durable, tempered spring steel, it is designed to cope with vibration, heat, and regular use in industrial settings. This is a Genuine JAP part with Manufacturer Part Number (MPN) 20935, engineered specifically for the JAP 3/JAP3 engines used on small plant and machinery such as mixers, pumps, compressors, and generators. Correct throttle spring tension helps stabilise idle speed, improves throttle response, and supports reliable running across the rev range. Ideal for maintenance or restoration, it fits directly in place of the original spring without modification.
Key Features:
- Genuine JAP part for assured compatibility and fitment (OEM No. 20935)
- Tempered spring steel construction for long service life in harsh environments
- Maintains correct throttle return for stable idle and responsive acceleration
- Direct replacement for the original spring on JAP 3 carburettor linkages
- Resistant to fatigue from constant cycling, vibration, and temperature changes
- Clean hook ends for straightforward installation using existing mounting points
- Helps reduce hunting and inconsistent throttle behaviour caused by weak springs
- Suitable for routine servicing or full engine rebuilds on period industrial equipment
Typical Applications:
Used on JAP Model 3 industrial engines powering compact construction and agricultural machinery, including cement mixers, generators, water pumps, and light compressors. Ideal when overhauling the carburettor, refreshing linkage components, or resolving poor return-to-idle and erratic throttle issues.
