In the interest of tire economy, the eompany has established a technical service department, made up of tire engineers who will give advice to any on engaged in truck operation. A full statement of any tire problem from any truck operator will' bring a detailed reply from the service de- partment, giving the latest scientific information on the points involved, “We intend that the technical sery- ice department shall be used freely by every person who owns a truck,” says C. K. Whidden, manager -of truck tire sales of the United States Tire Company. “Whether an owner is a patron or not makes no differ- ence, all our facilities for correct in- necessary, in order that his prob- lems may be satisfactorily solved. “Nearly half of the trucks of the country "are operating on the wrong kind of tires. This is a condition we hope to correct.” THE SUNDAY STAR, WASHINGTON, ‘D. C, AUGUST 7, 1921-PART 3. QUESTIONS AND ANSWERS FOR THE AUTOMOBILISTS — How.to Grind Valve. In cases where a badly pitted valve requires grinding, here is a short cut: Cut . piece of emery-cloth in dimen- | sions a little bit wider than the valve seating apd twice as long, and then double it over so that both surfaces are cutting surfaces. Next cut a hole in the cloth so that the valve stem may be passed through and the em- ery-cloth brought close up against if the valve turns and the emery- cloth remains stationary the, valve will be ground on the.upper emery, whereas if -the cloth revolves. the valve seating will be ground on the: lower emery. The economical upkeep, the pronounced riding com- fort, and the good general service ‘it renders, are steadily increasing the pop- ularity of the good Maxwell with the average family. H. B.

Do this before anything else is attempted, to hold. the car on the 21ill. Then place the gears in neu- tral and start the' engine. Keeping the -emergency, disengage the clutch, mesh the low speed gears, advance the hand throttle lever to speed up the engine, then let up the chutch pedal until the clutch begins to take hold. With the engine starting to pull the car, release the emergency ! brakes and slowly let the clutch pedal in the full distance. The car will then be going forward in low gear. If a shift from low to second is desired retard fully the throttle lever, disengage clutch and shift gears to second, speeding up the en- gine with foot accelerator while re- engaging clutch. Manlpulation of clutch pedal and gearshift leyer must be done quickly, to prevent the car from coming to a standstill when clutch is not engaged. Recause of increased load when the car is going up hill, care must be taken that the clutch 'is not engaged too quickly, also that the engine is speeded up sufficiently to receive the load when clutch is engaged, to prevent stall- in sarly spark and late spark are merely terms to designate how the spark is timed by manipulation of the spark control lever, early spark meaning spark occurring a trifle be- fore the beginning of power stroke of each piston, caused by advancing the spark lever, and late spark mean- ing spark ocourring at the beginning or a trifie after beginning of power stroke and~caused by retarding the spark lever. 3.

If an engine with magneto ig- nition continues to run after the igni- zion is switched off, the trouble lies in the magneto ground wire, which may be disconnected, loose or broken. Some- times a break in the wire may be un- I noticed because the insulation around the wire may not be damaged. 5.

This is usually caused by looseness due to wear in the universal joints, the rear axle unit and the transmis- sion. Play between gear teeth will cause a back-and-forth movement of the gears at slow speed or when the car 1s coasting. Play in bearings of these units also will be notices - |and wear in the universals will ne only affect the running of the car, but also will cause rattling. | 7. A scraping sound in a rear wheel could be caused by sand working in between brake band and drum, or, more commonly, by either inner or outer brake band or parts which operate them being in’contact with the brake drum. 8. To obtain smooth running without misfiring in an engine at low speed. the spark must be set so that tbe cylinders will not fire too soon at retarded spark, the high-tension spark coil must be free from short- circults, the battery must be in good condition and well charged; contact points in timer must be clean, flat and adjusted to tHe correct spacing, aistributor points should be clean and not worn. carburetor should be care- fully adjusted when the engine fis warm and there should be good com- pression in all cylinders, well seating valves being the most important to good compression. It also is neces- sary to use good spark plugs with points the proper distance apart.

The majority of automobiles are owned by farmers and people living in small towns. In these towns—of 1,000 or less people—there are 33 per cent of the country's registered cars. In large cities of 500.000 population or more the cars average only about 9 per cent of the total number. ‘This Week's Questions. 1. How can you tell when your en- gine is losing compr. 2 2.
