Decompression valve
It is important that this is tight for the
engine to work at full power.
Rub down the valve disc with fine grin-
ding paste if it is not tight.
Wash the valve carefully to remove all the
grinding paste.
Check the tightness of the valve as follows:
1. Connect pressure gauge
502 50 38-01 to the valves thread.
2. Pump up the pressure to 80 kPa (0.8
bar).
3. Check the pressure after 30 sec. It
must not be less than 60 kPa (0.6
bar). If so, rub down the valve disc
again.
