RÉSUMÉ
It will now be seen that troubles may arise from any of the six following sources:—
| Ignition | Lubrication |
| Carburation | Circulation, and |
| Compression | Moving parts |
I have tried to classify all possible troubles according to their symptoms, so as to make it easy for the novice quickly to locate the root of evil and rectify the fault.
CONCLUDING ADVICE AND REMARKS
If your motor works well, leave it alone, although it may never seem fast enough. Many troubles arise from interference and undue curiosity.
Remember that petrol is a highly volatile and inflammable liquid; its vapour is equally dangerous.
Make sure that all petrol connections and unions are taut.
If you have a flare-up, immediately close the supply cocks or let off the pressure, take off bonnet to save the paint, and smother the flames, or let them burn out. Water should only be thrown to save woodwork.
Do not pour petrol near a naked light; it is prudent to extinguish the burners when filling the tanks of the car.
Do not spill the petrol over your clothes and then strike a match to light your pipe.
Do not go out even for a short run without complete equipment of tools, spare parts, petrol, and repair outfit, or you may be back late.
Do not let a willing ostler fill up your petrol tank with water.
Do not leave the water in your car on a frosty night, except with 20 per cent, of glycerine in it.
