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.

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.

In addition, Weber never made a 50mm carburettor for large displacement or racing applications.

Carburettor Size - 50mm

Please Note
* The engine cc range in the listings is an approximation based on typical displacement requirements utilising standard (stock) ported cylinder heads and factory style cams.
Any carb sets / manifolds should always be matched to the head port size for the standard (stock) engines.
 
**Engines with enlarged ports, higher compression ratios, race camshafts, will require additional components for tuning beyond the standard kit

About PMO Carburetors

The PMO carburetor was designed from the beginning to be a state-of-the art carburetor. They start off with a casting designed around a 50mm throttle plate and downsized to 46 and 40mm to achieve three different sizes. They use an excellent material and process: A-356 aircraft aluminum and permanent mold casting. Permanent mold casting is a preferred method in the aerospace industry. This compares favorably with conventional carburetors, including Weber, which are die cast pot metal.

Since they designed a larger carburetor from scratch, the air entry and flow is much greater than the three barrel Weber. This is accomplished by having larger main barrels in the throttle body, tapering the top covers and then installing larger diameter velocity stacks of corresponding taper. This maintains the boost from the velocity stacks down to the exact point where it operates on the auxiliary venturis.

  • Ball Bearing Supported Single Throttle Shaft
  • Replaceable Idle Air Jets
  • Float Bowl Sight Glass
  • Full Range of Venturis, Jets, Emulsion Tubes
  • Float Bowl & Float Improvements
  • Two Sizes of Auxiliary Venturis
  • Heat Treated Aluminum Permanent Mold Castings

NOTE:PMO recommends using their Carburetor Insulator Kit, between the head and the manifold when installing these carburetors. Insulators restrict heat transfer from the head to the carburetor float bowl to prevent percolation. The kit includes insulators for two carburetors, gaskets, and longer stainless steel head studs. When purchasing Carburetor Insulator, Manifold to Head, Kit. Include information of carburetor size, year/type of head, and intake port diameter.

 

Design911 recommends that upon removing manifolds, simply apply liquid wrench to the base of the stud and let stand for a day or two before attempting to remove the head studs.
