Stihl Cutquik TS 460 - Carburetor Leakage Testing; Carburetor Servicing

STIHL TS 460 65
10.4 Leakage Testing the
Carburetor
10.5 Servicing the
Carburetor
The carburetor can be tested
for leaks with the carburetor
and crankcase tester.
- Remove the carburetor, see
10.3
- Push the fuel line onto the
carburetor's elbow connector.
- Push the nipple into the
tester's pressure hose.
- Close the vent screw on the
rubber bulb and pump air into
the carburetor until the pressure
gauge shows a reading of
approx. 0.8 bar.
If this pressure remains constant,
the carburetor is airtight. However,
if it drops, there are two possible
causes:
1. The inlet needle is not sealing
(foreign matter in valve seat or
sealing cone of inlet needle is
damaged or inlet control lever
sticking).
2. The metering diaphragm is
damaged.
In either case the carburetor must
be removed and serviced.
It is advisable to check the
servicability of the fuel pump
whenever the carburetor is
removed for repair.
- Remove the carburetor - see
10.3.
- Unscrew the fuel pump end
cover and remove the gasket
and pump diaphragm.
