This rebuild kit is for the Mikuni 40PHH Performance Carburetor. This #Z70-1040 kit is not for the Mikuni Solex Type 3 40PHH (See #Z70-1044S4-1) or Type 4 40PHH (See #Z70-1044) Carburetors. One main difference between Mikuni Performance Aftermarket Carburetors and Mikuni Solex OE carburetors is the Float Chamber Cover. The Float Chamber Cover is item #17, the Float Chamber Cover Gasket is item #18, in the exploded view. Please be sure your Float Chamber Cover Gasket matches the gasket pictured. See Float Chamber Cover Gaskets pictured for identification.

To identify the size of Mikuni PHH Carburetor, the Throttle Plate (Valve) of a 44PHH will be stamped 175. A 40PHH will be stamped 165. Please confirm your Mikuni PHH carburetor type, size and match the items pictured, prior to ordering.

Note: For the Mikuni / Solex Type T 40PHH Carburetor application, please see Gasket Rebuild Kit #Z70-1040T5 or Gasket Rebuild Kit Package with the Pump Diaphragm and Figure 8 O-Rings #Z70-1040TS+PDFE. This was a OE Toyota carburetor commonly found on 18RG and 2TC/3TC applications.

We now offer a gasket rebuild kit for the 40PHH and 44PHH Mikuni / Solex OE Type 3 S4 Four Bolt FCC applications. Please see gasket rebuild kit packages #Z70-1044S4-1 and #Z70-1044S4-1+PDFE.
