Dismantlingthe carburetor
Clamp the clearing saw in fixture No 5025103-01.
Remove the cylinder casing and blow as much dirt as
possible away from the area round the carburetor,
using compressed air.
Remove the sparking plug cover and air cleaner. Do not
yet remove the plastic sleeve over the carburetor adju-
sting screws as this is held in place by anail.
Fig 4:2
Close the choke flap to prevent dirt from entering the
cylinder. Disconnect the fuel line and back off the two
nuts (nut driver No 50250 22-01) holding the carburet-
or in place.
Open the choke flap and pull the carburetor straight
out to the rear.
Fig 4.3
Remove the small nail holding the plastic sleeve in posi-
tion over the adjusting screws and remove the sleeve.
Clean the outside of the carburetor.
Fig 4.4
Back off the four screws holding the diaphragm cover in
place and remove the cover. Remove the diaphragm.
Note that the centre stud of the diaphragm enters a
fork-shaped opening in the needle valve lever.
Fig 4.5
Connect pressure tester No. 5025038-01 to the fuel in-
let on the carburetor and pump it up to apressure of
0.03 MPa (0.3 kgf/cmq).
Check whether any leakage occurs at the needle valve
or at the gasket on the pump side. Leakage points can
most easily be located by dripping petrol onto the places
where leakage is suspected.
Fig 4.6
Back off the screw holding the shaft on which the lever
pivots and remove lever, shaft, spring and needle valve.
