PIK-20 E Service manual
The extended position is adjusted with the lever against the
chain lock and by tautening the safety wire.
Note 14 Engine brake
When the engine doors are closed, there should be about
1 mm (0.04 in) gap between the brake lining and magneto
wheel gear disc.
When changing linings, remove the old lining and clean the
surfaces carefully with grade 100 sanding paper. Bond the new
lining with epoxy glue. The new lining is best to be fitted on its
own place by leaving it in press with the engine doors open.
Avoid too thick glue layer. Do not turn the engine until the glue
is hardened.
Normal automobile brake lining material can be used.
Note 15 Lubricating the retracting mechanism
In many hinges there are holes for a grease press. Grease con
taining molybdenium sulphite is recommended.
Note 16 Adjusting the idling
Synchronize the movement of the throttle valves by adjusting
the idling position screws and cables. The mixture screws
should be opened about a 3/4 turn (5/8 to 7/8).
Warm up the engine and adjust it to run about 2000 rpm by
turning the throttle idle position screws equally. Try to make
the engine run smoother by turning the mixture screws within
the limits one at a time. To check that the both cylinders are
running equally, open one throttle at a time and listen if this af
fects the run equally. When the idling is adjusted, check the
synchronizing of the throttles.
