This spring is used on Solex 40 PII-4 carburetors fitted to Porsche 356 and 912 models. It mounts to the throttle linkage / butterfly lever on the carburetor, hooked between the throttle shaft arm and a fixed point on the carb body or bracket.
Sold each. There are two springs (for dual carb setup) on cars with twin carburetors.

Porsche 356 (1950-1955)
Porsche 356A (1955-1960)
Porsche 356B (1960-1963)

• This spring mounts on the throttle mechanism and provides return force, retracting the throttle valve (or linkage) when the accelerator is released.
• Provides tension that ensures the throttle valve doesn’t stick or hang open, which maintains safe and predictable engine operation.
• Helps maintain consistent throttle response and prevents the linkage from going “over-center” (which could cause the throttle to stay open).
With age, the spring can weaken, fatigue, deform or corrode, reducing its ability to pull the throttle shut securely. Proper replacement restores crisp throttle response, safe idle return behaviour, and reliable drivability. Using a matching (OE Match) spring ensures correct tension, length, hook geometry, and compatibility with the carburetor’s original design.

The spacer is designed to sit between the carburettor base (typically a SOLEX 40 PII-4) and the intake manifold on classic Porsche models - 356 B/356 C and 912, manufactured to match Porsche OE specification.
Sold each, 4 required per vehicle.

This spacer provides the correct separation and sealing interface, ensuring proper carburettor alignment, uniform port matching and preventing heat soak from the manifold into the carburettor. It is manufactured from a high-temperature-resistant to replicate the original design and maintain correct insulating properties.
Ideal for engine rebuilds, intake servicing or performance restoration, this spacer restores the intended clearance, port geometry, and sealing integrity required for reliable induction performance in classic Porsche engines.
Over time, the original spacer can deteriorate, warp or crack because of exposure to heat cycling, vibration and fuel vapour. A compromised spacer may lead to vacuum leaks, mis-metered fuel/air mixture, uneven idle or reduced performance.
Replace this spacer when:
• Performing a carburettor or intake manifold service or rebuild
• The original spacer is cracked, delaminated or missing
• Vacuum leaks or rough idle suggest induction sealing problems
• Restoring a classic Porsche engine to factory specification
Fitting new spacer ensures the correct spacing, proper sealing and authentic air-flow behaviour you need for lasting engine performance and reliability.

Precision Carburetors & Components – Heritage
Performance and Reliability for Porsche Classics
Carburetors remain the beating heart of many classic
Porsche engines, delivering the perfect air-fuel mixture for smooth,
responsive combustion. At Design911, we offer a comprehensive range of high-quality
carburetors and replacement components designed to maintain or enhance the
authentic driving experience of vintage and air-cooled Porsche models.
From complete carburetor assemblies to jets, diaphragms, gaskets, floats, and linkages, our products are engineered to precise manufacturer standards, ensuring consistent performance, easy tuning, and reliable fuel delivery — whether for restoration or motorsport use.
What Do Carburetors and Carburetor Parts Do?
A carburetor’s role is to blend fuel and air in the correct ratio before it enters the engine. This process ensures efficient combustion, smooth throttle response, and optimal power output.
Core Functions:
- Regulate
air-fuel mixture for various engine speeds and loads.
- Deliver
consistent fuel flow for smooth idling and acceleration.
- Maintain
throttle response across changing temperatures and altitudes.
- Support efficient combustion and improved drivability in heritage engines.
Modern performance replacements and rebuild kits allow older Porsche models to retain their period-correct feel while achieving modern levels of reliability.
Why Do Carburetors Fail?
Over time, carburetors and their internal components degrade
due to fuel varnish, dirt contamination, and mechanical wear. Common
failure symptoms include:
- Hard
starting or stalling due to clogged jets or passages.
- Uneven
idling or misfiring from air leaks or worn gaskets.
- Poor
acceleration or fuel economy caused by sticking floats or needle
valves.
- Fuel leaks or drips from perished seals or warped housings.
Regular inspection and replacement of worn parts prevent poor performance, fuel inefficiency, and potential engine damage.
Why Replace with Precision-Engineered Carburetor Components?
Replacing worn components with precision-engineered carburetor parts ensures your Porsche’s engine maintains its legendary throttle feel and power delivery.
Key Benefits:
- Restores
consistent air-fuel mixing and smooth engine operation.
- Improves cold starting and throttle response.
- Eliminates
leaks and uneven idle, improving drivability.
- Extends
engine life through correct fueling and reduced detonation risk.
- Maintains
heritage authenticity with manufacturer-quality materials and
machining.
- Perfect compatibility with period-correct Porsche carburetor systems (e.g., Weber, Solex, Zenith).
Whether you’re rebuilding a classic 911, 914, or 356, our selection of carburetors and components delivers modern precision with period-correct performance.
Highlights:
- Complete
range of carburetors and rebuild components for Porsche classics.
- Precision-machined
parts ensure reliable fuel delivery and response.
- Manufacturer-quality
fitment for seamless installation.
- Improved
combustion efficiency and performance consistency.
- Compatible with Weber, Solex, and Zenith systems.
- Ideal for engine restorations, rebuilds, and tuning projects.
