Tech

1. Float Height:

   When trying to lean out the full throttle / low rpm area.

   1. 13mm is too low to use. 

      1. The pilot jet gets exposed to air at high rpm / full throttle at 13mm.
         There are other issues, but they are beyond the scope of most readers.
         If you have an EC997 dyno, you can see what they are.
          

   2. 11mm works. 10mm, 12mm works.
       

   Note:
   
   The float bowl does NOT run out of fuel if the float height / fuel level is lowered - When the engine is pulling max fuel, the fuel level in the carb drops, usually, 1mm-2mm and then stabilizes.
   If the float bowl were to actually "run out" of fuel - it would mean that ANY float height setting would eventually run out of fuel if you held the throttle on long enough.
   
   The best way to test that is to use an EC997 dyno and do a LONG full throttle / high rpm test for 6-10 seconds (usual is 2-4 seconds)  and watch the 4 gas EGA trace and see if it leans out or not.

	The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved. Edited to the tunes of Chemical Residue by Herbie Hancock.
