Venturi Guide Funnel / Air Inlet Sleeve - part number 61610093000 - is a precision-cast 32 mm air guide insert designed for use in Solex carburetors fitted to Porsche 356 and 912 engines. This venturi element controls and accelerates incoming air through the carburetor throat, optimizing pressure drop and improving air-fuel atomization for smooth, balanced engine performance.
Sold each, 2 required per vehicle.
Fits:
Porsche 356B/C 1600 S90/SC 1960 - 1965
Porsche 912 1965 - 1969

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.

Ideal for restoration projects, carburettor rebuilds, or hardware replacements, it restores factory-correct mounting geometry and reliability.
• Function: Secures carburettor to intake manifold and maintains proper height / insulation
• Position: Intake manifold / carburettor junction
• Benefits: OE-spec fit, proper carburettor positioning, reduced heat transfer
• Installation: Direct-fit replacement; torque to factory specification with new washers and gaskets
Carburettor spacer bolts are exposed to heat cycles, vibration, and corrosion, which can cause thread wear, warping, or loss of proper carburettor seating over time.
Replace this part when:
• Threads are stripped or corroded
• Carburettor mounting is loose or misaligned
• During intake or carburettor rebuilds
• You notice vacuum leaks or fuel irregularities
Installing a new Spacer Bolt ensures a tight, stable carburettor fit, restores correct intake geometry, and maintains smooth, reliable performance on your Porsche 356 or 912.

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.
