The pump check valve is manufactured to replace the original valve listed by Porsche under part number 616-100-943-01. It is used inside the carburettor body of early Porsche models (356, 912, early 911) equipped with Solex carburetor systems.
Fits:
Porsche 356 B/C - 1600 S90/SC - 1960 - 1965
Porsche 912 1.6L 1965 - 1968 (Engine code: 616/36/37)
Diagram ref no 24
This valve ensures correct one-way flow of fuel or air inside the carburettor circuit, prevents backflow, and helps maintain correct mixture and idle characteristics. It is ideally suited for carburettor rebuilds, tuning projects, or restoration of original induction systems.
• Function: Ensures one-way flow within the carburettor system; prevents backflow
• Position: Inside carburettor body
• Benefits: OE-geometry, reliable sealing, restores proper mixture control, long life
The check/ball-valve is a small but critical component inside the carburettor that undergoes repeated movement, contact with fuel and vapour, and constant temperature cycling. Over time, the seat or ball may wear, the seal may fail or corrode, resulting in fuel or air leakage, poor idle, mixture inconsistencies, or even flooding.
Replace this valve when:
• Rebuilding or servicing the carburettor unit
• Noted unstable idle, mixture issues or back-flow in the carburettor
• The original valve shows signs of wear, corrosion or stickiness
• You’re restoring the induction system to original specification
Installing a new valve ensures correct flow control, dependable carburettor function and contributes to smooth, period-correct performance in your classic Porsche.

• Function: Regulates fuel flow through the pump / transition circuit in the carburetor
• Position: Within the carburetor body, pump / high-demand fuel circuit
Over time, metering jets like the pump jet may suffer from erosion, corrosion, or deformation, especially due to fuel additives or long‐term use. A worn or mis-sized jet can lead to rich/lean conditions, hesitation, flat spots during acceleration, or unstable mixture transitions.
Replace this jet when:
• You are performing a full carburetor rebuild or overhaul
• Your engine shows hesitation, poor acceleration or throttle flat spots
• The original jet is missing, damaged, or shows signs of internal wear.
• You want to restore factory-correct fuel metering for reliable classic Porsche performance.
Installing a new Pump Jet ensures accurate fuel delivery, consistent mixture behaviour and helps maintain the authentic feel and smooth acceleration of your classic Porsche.

This set combines two key components from the idle-circuit of the Solex carburettor used on Porsche 356 B/C and early 912 models:
• Idle Adjusting Screw ( 616100927010) - a fine-thread steel screw which allows precise adjustment of the throttle-plate position at idle, controlling airflow and engine RPM.
• Pressure/Compression Spring (61610081400) - the matched spring which seats under the adjusting screw and maintains the correct preload and return force on the idle throttle plate.
Together they provide stable, repeatable idle setting and crisp low-speed throttle transition. It produced in correct dimensions, thread pitch, spring rate and material to ensure the idle system works as intended by Porsche.

The OE Match venturi perfectly replicates the internal taper, contour, and surface finish of the original Porsche component. Its precision-machined dimensions ensure accurate airflow calibration and consistent response across all engine speeds.
• Diameter: 32 mm
• Function: Shapes and accelerates airflow through the carburetor venturi
• Fitment: Porsche 356 / 912 engines with Solex carburetors
• Position: Carburetor air intake throat
• Benefits: Restores original flow efficiency, enhances atomization, improves throttle response
• Installation: Press-fit into carburetor body; ensure correct orientation for airflow direction
Ideal for carburetor rebuilds, tuning, or period-correct restorations, this venturi restores authentic drivability, throttle smoothness, and performance efficiency in classic air-cooled Porsche engines.
Venturi inserts are critical for maintaining the proper airflow characteristics within the carburetor. Over time, the original funnels can suffer from corrosion, deformation, or buildup of carbon and fuel residue, leading to poor mixture quality and reduced performance.
Replace this part when:
• Performing a carburetor rebuild or tuning service
• The original venturi shows wear, pitting, or distortion
• Upgrading to restore original performance calibration
• Replacing damaged or missing venturi sleeves
Installing a new 32 mm Venturi Funnel ensures consistent airflow, crisp throttle response, and the precise carburetor performance your classic Porsche was engineered for.

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.
