Here we will be removing the mystery on how to modify the Weber F11 Emulsion Tube or any other emulsion tube.
The engine I'm working on is the 2056cc type 4 Porsche engine. The internals on this engine are stock. Also the jetting on your carbs must be dead on when doing this! Only 2 holes any ware below the Crown are recommended per Emulsion Tube for this Mods. A vacuum gauge and wide-band or Narrow-band are Highly recommended. Do Not Try This Without Them!
The twin Weber China clones are 44 IDFs.
The current jetting are for reference only and are as fallows:
Idle jets .52mm
Main jets 1.30mm
Air jets 2.20mm
Venturi 32.00mm not 36.00mm
Good Luck!❤

P.S. I know you got this!
