gram 12 on the previous page.
Maintain a high level of cleanliness when assem-
bling the carburettor. The slightest contamination
can result in running problems.
1. If the throttle and choke valves, together with
levers and springs were removed, they should
be refitted. Lubricate the spindle bearings with
light oil.
2. Fit the high and low speed screws and springs.
Note! Do not fully tighten the screws. This will
damage the seats and needle tips.
3. Fit the fuel filter (L) by using the handle of a
small screwdriver. See fig. 13.
4. Fit the pump diaphragm (K), gasket (J) and
cover (J) on the pump unit. See fig. 13.
5. Fit the needle valve (H) with lever, spindle and
spring and tighten the screw (G). See fig. 14.
6. Check with a ruler or the like that the lever is
level with the cover face. See fig. 15. If
necessary, the lever can be bent slightly.
7. Fit the control diaphragm (F) with packing and
cover (E) on the metering unit. See fig. 16.
