Porsche 356 B/C 1.6 01/59-12/65
Porsche 912 1.6 01/65-07/68

Diagram ref no 42 and 43.

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.

About Carburetors & Parts

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.
