CHECKING THE AUTOMATIC STARTER

•
Check that the automatic starter piston is not scored or
oxidized.
•
Check that the piston can run smoothly into its mount.
•
Check that the piston seal is not out of shape.
•
The starter must be switched on and off depending on
the room temperature.
•
Measure the piston jut, as shown in the figure, and
check the corresponding value.
•
Make sure that the starter is set to room temperature.
Jut value: 12.5 ÷ 13 mm at about 20°C
•
The starter will have to switch progressively off
means of the electric heating.
•
Check starter resistance with the starter set to room
temperature.
Resistance: about 30 ohm
•
Using a 12 V battery, feed the automatic starter and
check that the piston reaches max. jut.
Max. jut: 18.5 ÷ 19 mm
Max. time: 5 min
•
Heating real time depends on room temperature.
•
In case of juts, resistances or times different from the
recommended ones, change the starter.
•
Fit starter to carburetor. Take care to correctly position
the OR-seal, install the knurled plate on the starter,
and tighten the two screws (1).
•
Aim the starter as shown in the figure.
•
Fit the protective cover.
