Cleaning and checking
Clean all units in clean petrol.
Use compressed air to dry the petrol on the compo-
nents. Direct the air through all channels in the carbu-
rettor housing and ensure that they are not blocked.
Check the following:
1. That gasket, pump and control diaphragms are
undamaged.
2. That there is no play on the throttle and choke
valve shafts.

Assembling the carburettor
Observe cleanliness when assembling the car-
burettor. The slightest contamination can cause
malfunctions.
1. If throttle and choke valves with shafts, lever arms
and springs are removed, these shall be assem-
bled. The springs are tightened 1-2 revolutions.
Lubricate the shaft bearings using a light oil.
2. Assemble the high- and low-speed screws with
springs. Note! Do not tighten the screws against
the bases. This will damage seats and needle tips.
3. Assemble the fuel screen M using the handle of a
small screwdriver, see figure 41.
4. Assemble membrane N with gasket P and tighten
the pump cover Q, see figure 47.
5. Assemble needle valve G with lever arm F, shaft E
and spring H, and tighten screw J, see figure 45.
6. Check using a ruler or the like that the lever is
level with the assembly plane on the cover. If ne-
cessary, the lever arm can be bent, see figure 46.
3. That the needle valve G and its lever arm F are not
worn, see figure 43.
4. That the fuel screen M is intact and clean, see
figure 43.
5. That the tips of the high L and low K speed need-
les are not damaged, see figure 44.
6. That the inlet manifold R is intact, see figure 43.
