PMO Carburetor Base Gasket Set — 50mm, 6-Piece | Air-Cooled Porsche 911 / 930 (PM-O134-0)

Running 50mm carburetors means you built the engine for a reason — don't let a tired base gasket undo it. The PMO 50mm Carburetor Base Gasket Set (PM-O134-0) is the full six-piece set for the largest PMO bore, so you can reseal both carburetors properly in one go rather than hunting an air leak one throttle bore at a time.

Features

• Six gaskets per set — one per throttle bore, both carburetors covered.
• Cut specifically for 50mm carburetor bases, with correct bolt-hole spacing and thickness.
• Manufactured in the USA by PMO.
• Cheap insurance on a big-bore build — an unmetered air leak at the base will chase you through every other tuning change.

Does NOT fit: 40mm carburetors (use PM-O132-0) or 46mm carburetors (use PM-O133-0). Confirm your carburetor bore before ordering.
