Drilling The F11 Emulsion Tubes

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!
