CARBURETTOR
30 – English
Complete cleanliness is essential when reassembling the
carburettor. The smallest dirt particle can cause running
problems.
1. If the throttle and choke butterflies, together with their
spindles, lever arms and springs were removed, these
should be refitted. Lubricate the spindle bearings with
light oil.
2. Refit 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 filter (L) with the help of the handle of a
small screwdriver. See fig. 13.
4. Fit the pump diaphragm (K), gasket (J) and cover (I) of the
pump unit. See fig. 13.
5. Fit the needle valve (H) with lever arm, spindle and spring
and tighten the screw (G). See fig 14.
6. Check with a ruler or similar that the lever arm is level with
the cover face. See fig. 15. If necessary, the lever arm can
be bent slightly.
7. Fit the metering diaphragm (F) with gasket and refit the
cover (E) of the metering unit. See fig. 16.
8. Carry out pressure testing. See next page.
