Description:

PMO Induction utilizes aerospace quality castings, machining tolerances, IDF jetting and float technology that is based on Weber's most modern carburetor design. The original 46mm Weber carburetors 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 carburetors 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 carburetors 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 carburetors.

PMO Induction carburetors 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 carburetor 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 carburetor for large displacement or racing applications.

Please Note:
* The engine cc range in the listings is an approximation based on typical displacement requirements utilizing 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.
