Hints for the Beginner
THE pleasures of Motor Cycling need no longer be confined to those with a knowledge of engineering. The simplicity and excellence of the present-day Motor Cycle make the pastime open to all who can ride a pedal cycle and observe the following hints :
Place the bicycle on the stand, unscrew filler cap nearest the saddle and fill the petrol tank. Fill up the oil compartment in fore part of tank, taking particular care that only best quality air-cooled oil is used, Next lubricate the engine, giving say, five pumpfuls of oil. The' petrol tap should now be turned on and the small button on the top of the float chamber depressed until the petrol overflows the carburettor.
For easy starting it will sometimes be found necessary to inject a small quantity of petrol into the engine, by means of the compression tap placed on the cylinder head. This treatment is only necessary when the engine is cold, as owing to the congealed oil round the piston rings, it is sometimes difficult to revolve the engine at the speed required for starting. Paraffin should be used in preference if possible, as being a lubricant; it softens the oil and does not leave the piston dry, as is the case when petrol is used.
The bicycle still being on the stand, the rider should mount and proceed as follows :-
(1) Advance the spark lever to nearly full ;
(2) Open the throttle lever about one-half (control levers open from left to right);
(3) Close the air lever (this lever is the smaller of the two) ;
(4) Lift the exhaust valve by means of the lever on left hand side of bar; (5) Give a few sharp turns of the pedals and
(6) Drop the valve lever smartly, when the engine will begin to fire;
(7) Open the air lever immediately, giving air to suit, so as to obtain a correct mixture, The admission of too much air will cause misfiring, but it is always well to give as much air as the engine can take.
Now let the engine run for a few minutes on the stand, carefully observing the results obtained by opening and closing the throttle, operating valve lifter and advancing and retarding the spark.
After these preliminaries, dismount, fix stand back in position, and wheel the bicycle on to the road, holding up the exhaust valve lifter while wheeling the machine along. Set control levers as before, see that the pedal on the mounting side is down, run for a few yards, drop the valve lever and mount by the pedal the moment the engine fires. When seated, open the air lever as before, advance spark a little by pulling lever towards you, and afterwards control as much as possible by the gas lever, remembering that more air is required as the throttle is opened, to prevent the mixture from becoming too rich, thereby losing power as well as causing petrol to be wasted.
Lubrication is of special importance and it is much more satisfactory to lubricate little and often than to give large quantities at long intervals, We recommend a steady flow of about 50 drops per minute, but if the engine has heavy work to do this amount should be increased.
Experience, however, will soon teach the rider exactly what quantities should be used. Remember that, free engine and three-speed models require more lubrication than the ordinary fixed models.
Should the engine be over-lubricated, the exhaust will be very smoky and there will be a tendency to misfiring, due to oil on the sparking plug points. The piston top will become coated with a layer of carbonized oil which is detrimental to smooth running, and likely to produce pre-ignition in the cylinder. These minor troubles are easily remedied, however, and we should recommend over lubrication rather than under lubrication which may necessitate renewal of expensive engine parts. After running the engine say 300 miles, the dirty oil should be drained off through the drain plug, which is provided for this purpose at the foot of the crank case. Two more pumps of fresh oil should then be given before starting the engine.
The bearings of the bicycle also require lubrication, and hubs and spring fork fittings should receive special attention.
SPECIAL NOTE.-Do not overgear your machine, 5 to 1 will be found satisfactory for most touring districts.
If trouble is encountered the following advice may help to locate the fault :
Should the engine cease to fire without apparent reason - First ascertain if there is a sufficient supply of petrol in the tank, and that the tap is open, next flood the carburetter by pressing the button on float chamber as before. If the carburetter does not flood. it is quite possible there is an obstruction in the petrol pipe. Detach the pipe from the carburetter and note whether the petrol will then flow. Having made sure that the pipe is clear, take out the sparking plug, and examine the points to see if they are fouled with burnt oil. If this is the case, clean with petrol and set them as far apart as the thickness of an ordinary visiting card. Having cleaned the plug, couple same up to high tension cable, lay plug on top of cylinder, noting that only the metal body of plug makes contact with it. Then pedal engine round a few revolutions. A spark should appear at intervals at the plug points, but this may be prevented by the porcelain of the plug being cracked. In this case fit another plug, and should it still be impossible to obtain a spark, it is possible the magneto is at fault, although magnetos are now so near perfection that it is very seldom the cause of trouble. If the trouble is caused through a broken valve, this may be easily detected by a lack of compression, that is, the engine can be pedalled round without raising the exhaust valve. A valve which has been ground into the valve seating should always be carried as a spare. Note that inlet and exhaust valves are interchangeable. To obtain best results, we advise all riders at VICTORIA MOTOR CYCLES to pay strict attention to details. A supply of spare parts, including valve, plug, copper wire, and tyre repair outfit, should always be carried, and these should be carefully packed to prevent damage by chafing.
IMPORTANT.- When writing us with reference to Motor Cycles, always quote Type of Machine together with the Engine Number.
