Tech Tidbits

Float Height Measuring
Needle Jet wear
(sometimes called "worn emulsion tubes)
Inspect your brass needle jets for wear when you take out the needles. If the needle jets have oval wear pattern, they will allow excess fuel to pass by the needle causing excess low speed richness.
The fuel will also consist of large drops, rather than small drops. Large drops of fuel tend to drop out of the airflow and not burn.

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.
