OPERATION

TO START ENGINE.
1. Fill up with correct mixture (see above). It is best to mix the petrol just before using,
and not more than is required for immediate use. An old petrol n will be found
useful for mixing purposes. On no account should the mixture be made up in the
tank.
2. See that the land roll drive clutch is disengaged.
3. Pull out petrol cock at underside of tank and flood the carbure or by depressing the
ckler.
4. The posi on of control lever on right handle of machine for star ng should be
slightly open.
 To open thro le or admit gas to the engine, the control lever should be moved in
a clockwise direc on; the reverse direc on closes the thro le.
5. Close choke on cold days, kick engine over smartly when the engine should start in
two or three turns.
6. A er the engine is running, the posi on of control lever can be adjusted to give
required speed of engine and 'the choke opened.
FAILURE TO START.
If the engine will not start a er a reasonable number of trials, ascertain whether this is due
to lack of compression, faulty fuel supply, or faulty igni on.
FUEL SUPPLY.
Depress ckler at side of carbure or body. If fuel is reaching float chamber it will spurt out
of vent at top of ckler. It is important that the ven la ng hole in the filler cap of the fuel
{tank should not be allowed to become choked up.
IGNITION SYSTEM.
Unscrew sparking plug from cylinder head and place it, with igni on cable a ached, on a
metal por on of the engine. A spark should be visible at the plug points when the engine is
rotated if the plug and igni on system are in order. If there is no spark, try a new plug, or
alterna vely, check whether a spark occurs at the end of the igni on cable when this is held
about one-eighth inch away from a clean metal part of the engine.
If the engine will not start a er these preliminary tests lt the machine back on its handles
go that the drain plug on the engine crankcase is directly under the cranksha . Remove
drain plug and drain off any oil which may have accumulated in the crankcase.
If a er this the engine will not start, a more detailed examina on will be required.
Compression should be felt when the engine is rotated at normal star ng speeds with
thro le partly open.
