HORNER Amswers to Last Week's Questions. 1. When starting the engine the spark ever should be in the retard position. This facilitates easy start- ing, lessening the cranking operation and preventing the possibility of a back-kick. After engine starts ad- vance the spark about halfway on the steering wheel tangent, and allow it to remain in that position while the car is getting under way and gears are being shifted. When in high speed the spark lever may be moved to about three-fourths advanced for average driving speeds, advancing it fully for high speed and retarding to half or lower for low speed. When traveling any distance in a lower gear, such as on hills, or in sand or mud, advance the spark farther than it would be carried in high gear for average speeds, as the engine re- volves more rapidly. When in high gear and traveling slowly, the spatk should be retarded about half way before quick acceleration in the car speed is made. It is during this ac- celeration that the greatest strain is placed upon the engine, and when fully advanced spark would produce kuocking and laboring. Also when the car is straining through soft and rough roads, on high, do not overtax the engine by giving it too much spark advance—about half way up the tangent is enough. 2. There is no variation in the air pressure of tires for different se: sons, the specified pressure being in- tended for all seasons, warm or cold. Although there is some expansion in tire inflation in warm weather and especially during excessive speed at which the car may be driven, this ex- pansion is not noticeable and in no way endangers the tire if the correct inflatfon is maintained. The same ap- plies to contraction, which, if there is any, is slight in winter. 3. The oil gauge may vary in indi- cating pressure of the oil circulating through the engine under certain con- ditions, such as temperature, low oil level in crankcase, use of wrong oll or system being clogged. If the en- gine is cold the pressure registered {at the gauge will be greater when the machine is first started than: wher warmed by running, when the oil has ibecome thin. Oil which will not en- dure the cold test, which will congeal in winter, should not be used in the engine, as the pump circulating it cannot draw it from the oil pan. High pressure registered by the gauge may indicate that the circulation of oil has ceased because of clogging somewhere in the system. A safe FOR THE AUTOMOBILISTS or broken near the bead from under in- flation. If this were the case and the tire was retreaded, it would blow out long before the new tread was worn through. A tire, the tread of which is well worn, but firmly attached to the carcass and which has no deep cuts, pieces gouged from it or sand blisters and which has not been standing idle for a long period is safe for retreading. Any athers are not. 8. Aluminum alloy pistons usually require twice the clearance for ex- pansion in a cylinder of the cast iron piston. Clearance of the latter is gradudted, .001 inch being allowed for the lower half from bottom to top of the third ring groove for each inch of the piston’s diameter. The second ring groove requires .004 inches ad- ditional clearance, and the top ring groove about .012 inches more than the bottom half of the piston. These figures do not apply to all engines, some being fitted with pistons of from .002 to .004 per inch of piston diameter. . 9. Although there are tools which are designed to depress clutch springs while work is being done inside the clutch, an easy way for the autoist to hold his clutch in the dl!flll&leq po- sition is to depress the pedal'and place a prop or jack, extending from the base of the front seat, against it. Thus held, the released cone can be turned by hand for cleaning or ap- plying the necessary remedy. 10. Transmission gears operating correctly can be shifted with no grat- ing nolse whatever. Nolse in the changing of gears is caused by not disengaging the clutch sufficiently, by the clutch or transmission shaft drag- gIng or by wear in bearings in the shaft causing misalignment. A worn clutch brake is a common trouble, not stopping the swiftly revolving clutch quickly enough after it is dis- engaged. 3 Thix Week's Questions. 1. What action takes place within a storage battery when it is charged? 2. Why is a generator of electricity first rin as a motor after being over- hauled or when first assembled? 3. Has the clutch of a new car a tendency to slip? 4. How can a steering post be re- moved without injury? 5. It sometimes happens that a stalled car must be towed to a garage and there is no driver available to steer the machine in tow. By what arrangement are the two cars brought in with one driver? 6. 1s it possible for valves which are loose in their guides to produce a knock? 7. How can slots in the floor board of a car through which extend the brake and clutch pedal levers be closed to prevent the cold draft pass- ing through them to the car’s interior The: Chicagp’ Motor Club, the .la: est’ organization of ‘its. kind in. t! world, has just purchased twelve new 1922 model motor cycles of a popular make, with side vans, for use in its first aid work. The club has been using motor cycles since last May for this purpose, and is thoroughly soli¢ on the practicability of the efficient little. machine. The machines, which are palnted white, with the club’s emblem on the slde vans, are each manned by an expert mechanic, and are ready at a moment’s notice to end to calls from members who are experiencing difficulty with their cars. Another pioneer in the fleld is the Honolulu Automobile Club of Hono- lulu, H. T., who put their first motor cycle dispatch car into service in Au- gust. In the short time that has elapsed, the motor cycle has more than proved its efficlency. ‘With two such large organjzations as the Chicago and Honolulu auto clubs sponsoring the movement, it is quite safe to say that automobile as- soclations all over the country will soon be adopting motor cycles for use in’their first aid work. == Now that the motor cycle racing season is in full swing abroad, Amer- ican-made machines are coming in for their usual share of the victorfes. In the Webb memorial reliability trial, an annual affair of great importance in South African motor cycle circles, American machines took three place: the Harley-Davidson winning first and third and the In- dign" second. The trial was a very difficult one. being held over 280 miles of the worst roads in the country. The course extended. from Johannesburg to Rustenburg and return. American machines scored another big, victory in South Africa when the Harley-Davidson captured first, sec- | ond and fourth places in both the solo and side car classes In the strenuous 202-mile race held recently from Cape Town to Saldanha Bay and return. PERMIT LIGHT TESTS. Maryland and District traffic offi- cials have given permission for a test of the Garner {lluminated license cab- inet, which, by means of a small light illuminates the license tag by means reflection. The outlines of the num bers of a tag are cut out, the tag plac- ed in the cabinet and the light shows through the number outlines, making them visible for some distance in the Year. Invented by William R. Garner of this city, the cabinet is so construct- ed with the rear lamp and license sign to show clearly all the numbers on the tag. In the cabinet there is a re- Wi agreed satisfactory battery solution is diluted ' upon the pure solution that is put into e e i Papers for the it charged when necessary.

A hydrometer must be used to |test the specific gravtly of a storage ibattery. Clear water tests at 1000. When the acld is added to make the battery solution it becomes heavier, !testing at maximum strength of 1285 {to 1300. Thus. at full strength, the hydrometer will not sink as deeply into the solution as it would in thin or weak solution or water. With a fully charged battery all the acid .is imixed with the water in the cells. iWhen the battery is discharged the iplates within it absorb the acid, leav- jing the solution weaker or thinner, and when a hydrometer will sink jdeeper in the solution and indicate a llower gravity. The battery’s condi- {tion can be ascertained by a gravity {test of the solution with a hydrometer, although this test does mnot indicate {the condition of the individual sets of_positive or negative plates. 5. The carburetor auxiliary air inlet seldom need be changed for cold- weather driving, as it is necessary to admit extra air to tae carburetor mix- ture when the ‘engine is warm and for high speed running. The cold-air opening of the inlet manifold, however. can be closed almost eatirely in cold weather. This opening Is uudv to admit cooling air to the manifold heated by exhaust gases or hot water from the connection is made for a very short time, and in addition is ® sure way to ruin’the plates within, causing disinte- gration and buckling. ~7.
