Lube the chain by spraying chain lube on the
chain while manually rotating the rear wheel.
To replace the chain, loosen the engine and
slide it back to release the old chain from the
sprocket. Reverse the procedure after installing
a new chain.
Lubricate the throttle cable each time the
engine is run. Also check, and adjust the cable
as needed, to assure the correct throttle and
that the throttle returns properly and opens full
size.
If the cable frays, it must be replaced.
1.Take the intake silencer off the carburettor by
unscrewing the clamp. It is not necessary to
unscrew the bracket. The intake silencer will
turn easily.
2.Disconnect the throttle cable from the
carburetor together with its spring and slide it.
3.Took the carburetor off the engine and open
the float chamber (22) by unscrewing the four
screws (23). Clean the parts, openings and
passages with compressed air. Check the float
chamber gasket (21) and eventually change it if
damaged.
4. Close the float chamber by screwing the four
screws (23) and re-place the carburettor in the
engine.
