Product details

This PMO set supplies the gaskets, sealing washers, and pump diaphragms for resealing a pair of Weber 40-series three-barrel carburetors. It covers the carburetor base, top cover, and air-filter base, as well as several metering and fuel-fitting seals. Inspect the castings, shafts, and metering parts separately; a seal set does not replace worn mechanical parts.

Technical Details

  • Part number: PM-O260-0
  • Coverage: Two Weber 40-series three-barrel carburetors
  • Gaskets: Carburetor base, top cover and air-filter base
  • Fuel inlet seals: Fiber washers
  • Metering seals: Idle-jet holder O-rings and main-jet holder copper washers
  • Further washers: Float bowl plugs, float fulcrum pins and accelerator pump jets
  • Diaphragms: Inner and outer accelerator pump

Fitment & Compatibility

Confirm the Weber model and compare the gasket and diaphragm patterns before disassembly. This is a Weber 40-series kit, not a general kit for PMO or Zenith carburetors. Check fuel level, throttle synchronization, and mixture settings after the rebuilt carburetors are installed.
