REPAIR INSTRUCTIONS
To obtain the best engine performance, before
adjusting the carburetors, make sure that the
distributor dwell angle and ignition timing are
correct. The ignition timing should be checked
and adjusted by using a stroboscope with the
engine running at rapid idling speed and the
vacuum regulator disconnected.
I n addition to this, the spark plugs, ignition cables
and other ignition equipment should also be check-
ed. See the correct values in the specifications.
The instructions below concern only the carbure-
tors for the B 16 B engine. The Service Manual
for cars and vans, Part 1, B 16 A Engine should
also be used where applicable.
FUEL SYSTEM
Carburetors
The hollow spindle on the suction chamber piston
is filled with oil and functions together with the
small damping plunger (3, Fig. 8) as a damper.
This should be topped-up with oil at regular inter-
vals, for example when the engine oil is changed.
Screw off the nut at the top of the suction
chamber, lift up the nut and the damping plunger
and top-up with oil through the hole. Fill only the
centre spindle so that the oil does not run over
when the piston is fitted. Use SAE 20 engine oil.
