Ignition
The resetting of ignition timing requires a 12V
test lamp, a contact gauge (0.4mm = .016")
and a screw driver.
To perform the setting proceed as follows:
1. Withdraw sparkplug connector, unscrew
sparking plug and remove cover from blower
wheel as well as cover plate and rubber
covering from the ventilating housing.
2. Rotate blower wheel in a clockwise di-
rection until the color-marked blade meets the
mark "S" on the housing of the blower unit.
Now continue turning the blower wheel until
the breaker contact points are fully opened.
3. Check contact breaker gap with the contact
gauge (.016") (figure 62), which must slip
easily when being drawn for and aft between
the contact points. If the gap is too big or too
small, slacken the stationary point locking
screw 1 figure 63 and turn the eccentric
adjusting screw 2 figure 63 until the correct
gap is obtained. Then tighten lock screw 1
and recheck the gap.
4. Slacken the two contact breaker plate
securing screws (3) (figures 63 and 64) and
turn the blower wheel until the color-
marked blade meets the mark "S" on the
blower housing.
Now disconnect black-colored contact
breaker lead from terminal 1 of ignition coil
and connect the test lamp with one pole to
terminal 1 of ignition coil and the other to the
connector end of the disconnected black
lead.
5. Push in ignition key to switch on ignition
and move the contact breaker plate in
rotation direction (downwards) until the lamp
lights up. Then move contact breaker plate
(figure 65) carefully contrary to direction of
rotation (upwards) until the lamp just goes
out. In this position tighten the contact
breaker plate.
6. Withdraw ignition key to switch off ignition,
detach test lamp, reconnect contact breaker
lead to terminal 1 of ignition coil, refit cover of
blower wheel, replace spark plug and push
high-tension lead connector over the sparking
plug.
