PMO 46mm Triple-Throat Carburetor Kit for Porsche 911 3.2-3.4L (Performance) | PM-O806-0

The PMO 46mm Performance Carburetor Kit is the gold standard for air-cooled Porsche 911 carburetor conversions. Made in Anaheim, California from CNC-machined billet aluminum with aerospace-grade tolerances, PMO carbs solve every shortcoming of the original Weber IDA — eliminating throttle shaft wear, air leaks, and tuning headaches that plague decades-old Webers. Now manufactured under the EMPI banner, with the same Richard Parr engineering and Anaheim production.

Kit Includes

• Two PMO 46mm carburetors with 40mm chokes
• 165 main jets, 180 air correction jets, 60 idle jets
• F7t emulsion tubes, 0.5 float check valve
• PMO throttle linkage
• PMO fuel pressure regulator
• Carburetor isolators
• Complete hardware and fuel hose

Why PMO Over Weber IDA

• One-piece stainless steel throttle shafts with ball-bearing support — no more shaft wear, air leaks, or binding
• Full throttle body opening (Weber 46mm only enlarged the plate, not the bore) — significantly improved airflow
• Float bowl sight glasses for tool-free fuel level tuning
• Redesigned fuel inlet system for higher, more balanced flow
• IDF-derived jet and float technology — modern, mature design
• Heat-soak resistant construction

Fitment

• 1965-1989 Porsche 911 with 3.2-3.4L engine (3.2 Carrera primary application)
• 914-6 (with appropriate manifolds)
• Compatible with stock manifolds OR PMO billet manifolds (sold separately)
• Performance jetting — best suited for moderately built engines and lively street use

Made in Anaheim, California

PMO carbs are produced in PMO's California facility by EMPI. When founder Richard Parr retired, EMPI acquired PMO and invested in expanded machinery to keep the legacy alive. Same engineering. Same quality. American-made.

Note: Intake manifolds NOT included. Most installs use existing OE manifolds; PMO also offers CNC-machined billet replacement manifolds in 40/46/50mm sizes — ask us if you need them.

Installation: Final jetting may need adjustment for your specific engine setup. PMO publishes a Carb Setup Sheet — recommended to fill out before install. Professional tuning recommended for first-time PMO users.
