What the Product Does

• Controls the operation of the carburettor’s accelerator pump.
• Ensures the right amount of fuel is delivered during throttle transitions.
• Improves throttle response and driveability.
• Essential for maintaining proper carburettors tuning and performance.

Symptoms of a Worn or Failing Accelerator Pump Cam

• Flat spots or hesitation when accelerating.
• Poor throttle response.
• Engine stumbles or bogs under sudden throttle input.
• Inconsistent carburettor tuning, requiring frequent adjustments.

Common Reasons for Failure

• Wear & Tear: Repeated contact and movement cause gradual wear.
  
• Aging Material: Plastic or metal fatigue reduces precision over time.
  
• Improper Adjustment: Incorrect setup can stress or damage the cam.
  
• Contamination: Dirt or debris in the carburettor accelerates wear.

Why Replace?

• Restores smooth throttle response and consistent acceleration. 
• Improves engine performance and driveability.
• Prevents poor fuel delivery that can damage engine components.
• Keeps carburetted Porsche engines properly tuned and responsive.       

Ideal For: Porsche enthusiasts and restorers running PMO carburetors who want reliable, precise fuel delivery and smooth throttle performance.

PMO Induction 46mm Carburettor Kit - Performance Version

Replacing worn or faulty Weber carburettors or looking for increased performance? Choose PMO Induction carburetors

Weber carburettors are a good product, but they were designed for mass production. PMO Induction carburetors are highly engineered and designed to exacting standards tht are not feasible in typical mass production.

This is why we feel that PMO Induction carburetors are a superior product.
Please see the  PMO vs OE Carb Overview

Fits
Kit Includes
Carburettors, linkage and fuel regulator

PMO Induction utilises aerospace quality castings, machining tolerances, IDF jetting and float technology that is based on Weber's most modern carburettor design.

The original 46mm Weber carburettors simply have the throttle plate enlarged, whereas PMO’s have the
entire throttle body enlarged from the top throat through the plate meaning the air flow capabilities of
PMO Induction’s carburettors are significantly improved over the equivalent size Weber.

PMO Induction use a one-piece, machined stainless steel throttle shaft, supported by large ball
bearings for a lifetime of smooth throttle action negating the Weber carburettors biggest problem as
Weber carbs suffered greatly with throttle shaft wear, air leaks, and binding over the years. Weber throttles also suffer from heat soak
that exacerbate the wear issues but this does not affect PMO Induction carburettors.

The PMO Induction carburettors have a sight glass float bowl to allow for accurate setting of fuel levels,
much more simple and efficient than the Weber IDA method that requires partial a carburettor disassembly.
The fuel inlet system is also greatly improved to provide significantly improved flow capacity and fuel delivery balance against
the banjo set-up on the Weber carbs, which are highly prone to leak and are capacity limited on high flow applications.

Specification:
Carburettor Size - 46mm
Choke - 36
Mains - 145
Air Corrector - 185
Em Tubes - F11t
Idle Jets - 55
