Rabbit Convertible L4-1715cc 1.7L SOHC (1982)
Fig. 6 Air cone
The corrected cone shown with broken lines, causes the sensor plate to float higher with the same air flow that it would in a simple cone at idle. This
raises the control plunger slightly and richens the air/fuel mixture slightly, Fig. 6.
At part load the sensor plate and control plunger float lower than in a simple cone so that the air/fuel mixture is leaner.
