PMO Induction 50mm Carburettor Kit for Road Use
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.

FitsPorsche 911 - Air cooled engine with a capacity of 3.5ltr through to 3.8ltr
Kit IncludesCarburettors, 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.

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
