EXTERNAL GAS LEAKS.

Gas Leakage into and out of engine eyeliners and piping is met with in three general forms, viz.: Escape of gas while under compression in the cylinders; es cape of burned gas from the ex- haust system, and the entrance of, atray air into the intake system, Leakage of any of these kinds gives more or less serlags trouble and one has to be on the watch for it, be able to determine its nature and locate it.

The Strength to Give Miles

To set that constant need to flex and flex,

to take those sudden shocks and jars evenly and easily on low air pressure, the need is for a supremely strong and flexible body.

SUPERTWIST, the newly discovered cord material used exclusively in Goodyear Balloon Tyres, has proved in actual tests, that it far outstretches; far outilexes, far outwears, all other cords.

tendency and therefore air leak- age makes starting und steady running. at low speeds very diffi-X- cult. To locate air leaks, set the engine idling, soak u plece of waste with gasoline and hold this! closely around onch place where it may Be suspected that straÿ air can enter; such as the carburetor Aange, intake pipe fanges, the throttle shaft and inlet-valve stem guides. If the engine speeds up when the waste is pressed around any of these points there is an air leuking in thereat, which has taken up enough gasoline to in-; creuse the charge fired and raised the speed.

(Mr. Clough gives some of the questions he receives from time to time, together with the answers. These appear weekly and provide an instructive. refer- ence.)

This Engine an Oil Waster, Question: I have to fill the engine of my car with oil every 100 or 150 miles and it will hardly hold the thinner grade of oil used in winter at all. There is an es- cape past the felt washer around the front end of the crank-shaft, where it goes through the timing gear case, because this washer falls to pleees after a very short) time. The labour entailed in replacing it is rather costly. What can you suggest?'

Answer:..Is the shaft roughed up or out of true where it passes through the washer? Is the washer retainer out of centre. with the shaft? These defects may make the, felt give out premature- ly. Perhaps a better form of re-p tainer could be used that would support the felt more effectively and, possibly, a retainer that would carry a thicker washer might give better results. " We suggest that you take this matter jup with your service station or direct with the manufacturer. Of course, if your engine has a con- tinuously smoky exhaust, there is much oil-waste past the pistons. There may be other oil-leaks. Try ránning the engine idle at a good speed, when it is hot, and watch for oil droppings of the flour under it?

Question: Although I have just installed a new battery, the starter of my Ford will not start, the engine on cold mornings and does not seem to be strong, but after the engine becomes heated, it works perfectly. Would new wiring remove this trouble?

Ausicer: If the starter works all right after the engine becomes hot, we cannot see there is any reason to have it rewired, Is your, trouble that the starter will not turn the engine over as fast as it should on cold mornings, or is it that it turns it over at a good speed but without the cylinders firing? It the former is the case see if you cannot use an engine oil which will not stiffen so great- ly with cold, make sure that all the connections in the starter cir- cuit are tight, that the starter- switch contacts are clean and that the commutator and brushes of the starter-motor are in good condition? If the latter is the case make sure that the carbure tor-choke close tightly enough, that the commutator Js oiled with kerosene-oil mixture that the sparking-plug points are set right|| and that the magneto is.31ot weak. Try putting a litple gasoline Into cach cylinder before starting.

GOOD BUSINESS OUTLOOK.

Leaders in the automobile in- dustry predict a huge development of the industry in 1926. It is ex- pected that business conditions will be even more favourable dur- ing the coming year than they were in 1925.
