Mikuni PHH 40 and PHH 44 sidedraft carburetors are a licensed version of the famous Solex sidedraft carburetor. They may be marked Mikuni, Solex or both. They use the same base flange pattern as Weber DCOE and Dellorto DHLA carburetors. Mikuni was the brand Nissan Competition sold for A-series engines. Mikuni made the PHH series from around 1970 until 1995. A PHH 50 was also made but are too big for regular A-series engines. Mikuni "Solex" is far more popular than Webers in Japan.
- Mikuni calls the idle-mixture screw the "Pilot" screw.
- Carb flange same as DCOE. The air cleaner side bolts are spaced slightly different. Elongating DCOE air cleaner holes lets them fit on the PHH.
- Choke: A most interesting feature of the PHH is that instead of a choke butterfly valve for cold-start enrichment, it using an enriching circuit called a "starter" which rotates to open the starter jet.
- Starter: Yellow circles. Connect choke cable to these.
- Pilot Screws: yellow arrows
- Idle speed screws: Green arrows
- Mikuni PHH Carburetor Service Manual (PDF)
- Size is stamped on the throttle blade
- 165 = 1.65 inch (40 mm)
