Complete cleanliness is essential when reassembling the
carburettor. The smallest dirt particle can cause running
problems.
1. If the throttle and choke butteries, together
with their spindles, lever arms and springs were
removed, these should be retted. Lubricate the
spindle bearings with light oil.
2. Ret 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 lter (L) with the help of the handle
of a small screwdriver. See g. 13.
4. Fit the pump diaphragm (K), gasket (J) and cover (I)
of the pump unit. See g. 13.
5. Fit the needle valve (H) with lever arm, spindle and
spring and tighten the screw (G). See g 14.
6. Check with a ruler or similar that the lever arm is
level with the cover face. See g. 15. If necessary,
the lever arm can be bent slightly.
7. Fit the metering diaphragm (F) with gasket and ret
the cover (E) of the metering unit. See g. 16.
