formed or rusty.
- Check that the piston slides freely from the seat
to the support.
- Check that the piston sealing gasket is not de-
formed.
- The starter must be more or less functional de-
pending on the ambient temperature.
- Measure the protrusion of the piston as shown in
the figure and check its corresponding value.
- Make sure that the starter is adjusted for the am-
bient temperature.
- The starter should disconnect progressively by
means of electrical heating.
- Check the starter resistance when adjusted to the
ambient temperature.
With a 12V battery power the automatic starter and
check that the piston protrudes as much as possi-
ble.
- The correct warm up time depends on the ambi-
ent temperature.
- If protrusion, resistance or timing values are dif-
ferent from the ones prescribed, replace the start-
er.
- Assemble the starter to the carburettor being
careful to position the O-Ring correctly, insert the
plate with the machined side contacting the starter,
tighten the fixing screws.
