Complete cleanliness is essential when reassembling the
carburettor. The smallest dirt particle can cause running
problems.
1. If the throttle and choke butterfl ies, together
with
their spindles, lever arms and springs were
removed, these should be refitted. Lubricate the
spindle bearings with light oil.
2. Refi t the high and low speed jet screws and springs.
Note! Never tighten down the screws.
This can damage the seats and needle tips.
3. Position the fuel fi lter (L) with the help of the handle
of a small screwdriver. See fi g. 13.
4. Fit the pump diaphragm (K), gasket (J) and cover (I)
of the pump unit. See fi g. 13.
5. Fit the needle valve (H) with lever arm, spindle and
spring and tighten the screw (G). See fi g 14.
6. Check with a ruler or similar that the lever arm is
level with the cover face. See fi g. 15. If necessary,
the lever arm can be bent slightly.
7. Fit the metering diaphragm (F) with gasket and refi t
the cover (E) of the metering unit. See fi g. 16.
