MOTORING NOTES.

;; €XX&8 : QW2 BIST? OH. S Dirty o3 is injurious to an enginia. It wtdso means worn oil, which ; has been tssed ■ Z%oa long ; and; needs replacing. Once a :■' for the\Eiore used parts is not too frequent. : "A bearing on the ignition unit, the armature'bearings of the lighting ■ generator and , starting motor should be < -piled as directed by the manufacturer.

*-. v> . "WOBBLY*? WHEELS. ';, \\ '/' " Wobbly" wheels cause the tyres to ", wear twice as fast as they should. ,The wheels, therefore, should be watched con- , stantly and'tightened up as soon as they show a cign of wavering. Worn bearings might cause looseness in the' rear wheels, and the front wheels wobble because of rpiay in the bearings, spindle bashings, or- * steering connecting rod bushings. De- i mountable rpns not firmly bolted to the 'wheels may also cause trouble; " -

TO OVERCOME 3ER&S,"||; : .The fact that the car jerks w!hen ; throttled down below 15 nafles art bour r in* dicatcs that the carburetter is poor.' If it is impossible to adjast thegcarbu^ettoFV to overcome this jerking it is probably' caused by worn intake-valves. Ii these valves are loose enough to spin, there is ;. probably enough leakage toprevesit good carburetter adjustment. This condition allows the outside air to come in direct contact with the valve when it come in contact with the gas taken through the manifold. It causes condensation and a choking effect which makes the engine pull irregularly, causing the car to jerk.

LOOSENESS OF TREAD. Trouble is often experienced in getting ."the tread to stick on small tyre repairs. This may be due U> anyone of BeVeral reasons, the most common of wihch is that the -cement has been applied over wet fabric. •The moisture in the fabric, even if very "elight, will blow the tread loose. Another common cause for loose treads is the failure to-roughenyajkjthe old carcass sufficiently. In cement will not hold properly^vahd'aliter a few miles of running the repair yfijl separate. It is also, well to make"'sure' that proper pressure is being applied' to the repair when it is curing, so that the natch will be thoroughly embedded in the" tyre.

CARE 07 THE FAN-BELT. Undoubtedly, the crudest part of the engine is the fan-belt/and yet.it is a most important part. It certainly, is a most frequent source of trouble, "and -by that token demands ferquent, and careful attention by the car-owner. - All fanbelts are provided with an adjustment, some easy, some lees so," and; these adjustments are necessary. The wise motorist will not forget to give the fan a twist every tune he has the bonnet up. The best, results are attained when it is possible to turn the fan with considerable resistance, but not to spin it. If a quick twirl of the fan is followed by a little turning after the hand is removed, then the belt is too loose. Do not have it any tighter than necessary, for then it is under excessive strain, and will stretch wear, or break the sooner. '

'THE COST '. 'OF SPEED. .. The law is just as immutable in that it collt ;ts a greater cost for speed in a motorcar as it does of any machine or of man If you run fast, if you work hard, you reou.re_morefc.od. .If you drive your car- at {.feat speedall the time, it requires more fuel, morft.aetrol and intra oil. If you JS* *£H*d hardr you wear out more quickly and so does an automobile. Tyres for instance, last twice as long on J car that, is driven at 15 miles an hour a« tw do upon cars that are driven at V\ . -i y an hour. Remember thaTu! - " ules
