Information From The Hand Crank As To Whether An Engine's Cylinders Are Gas Tight Or Leaky A FEW MINUTES devoted to cranking an engine by hand will tell more as to its condition than will any other single test. It will indicate the degree of gas tightness possessed by each of its cylinders and this 13 by far the most important thing to know about it. If gas leaks from cylinders excessively, that is, if they have pocr compression, high output and economy cannot be expected. With the car in neutral and the fgnition switch off, remove all spark plugs but that of No. 1 cylinder and attach the hand crank. The engine should then crank perfectly freely until it is turned the point where both valves of No. 1 cylinder close, but at that point there should commence a strong resistance to cranking and when the crank is turned further, it should spring back positively, when turning force is removed. It should do this again and again, even though the crank is held for some time, with the com- pression pressure acting in the cylinder. test, its number can be set down as one which is tight. If a cylinder will pass this The spark- plug should then be moved to No. 2 cylinder and the same test repeated, but it may be that, in this instance, only a slight and temporary resist- ance is encountered, which socn ceases, if force is kept applied to the crank. escaping air can usually be heard hissing out. There is no "back spring" when the crank is released and the No. 2 cylinder will then have to be noted down as leaky. After all cylinders have thus been tested, by moving the spark plug and cranking, one will have a record ot which are leaking and it is these which require attention. Do not allow anything to be done to the valves of cylinders which are satisfactorily gas tight. It is fruitless and grinding may only impair their condition. Have only the valves in the leaky cylinders ground to perfect seating and their push-rods adjusted to the right clearance. It may be that after all this is carefully done one or more cylinders still fail to show springy compression reaistance, when cranked, in which case it is much to be feared that leakage is past the piston instead of at the valves. The result of such tests of cylinders for gas tightness, usually explains at once shortcomings in engine performance, such as low fuel economy, lack of hill climbing ability, "roughness" of operation, unusual vibration and uneven operation at slow speeds, Every two or three thovgand miles the handcranking test can profitably be made. RED HOT SPARK-PLUG y cf E. G. L. writes: The spark-plug in No. 2 eylinder of my four-cylinder engine, becomes. red hot and causes backfiring, after the car has run-four or five miles. Valve action and lubrication are all right. What causes this plug to overheat? Answer: If this particular plug is difterent from the others and not of the type recommended for use with this engine, especially if it is so long that it projects unduly far into . the combustion camber or has tco massive sparking points, its overheating is accounted for. An- otner cause of the same thing is a was leak through a plug, which will keep its metal parts hot enough to ignite the next incoming charge. Occasionally, if water circulation is sluggish or some of the passages in the cylinder-head are obstructed with sediment, a steam pocket may form and cause local overheating. If this involves the part of the head in which a spark-plug is located. the plug may run red hot. mera LEAKY TIMING-GEAR CASE W. H. H, writes: The oll leve In the crankcase of my ens gine gets low much sooner than formerly and I notice, that iter the car has stood idle in ths garage, there is some oil on the floor, not under the engine itself but rather in front of it and just a little back of the radiator. Where does this oil escape and how can I stop It from so doing? Answer: It probably leaks out from the timing-gear case. It may be that the bolts which hold the cover on have become loose and need tightening Suir. but quite like. ly the gasket between the cover and the case itself, is damaged and will have to be replaced before leakage can be stopped. You will have to empty the cooling system. detach the rubber water connec- tions and take off the radiator. be- fore you can get at the timing-gear case to work on it, Questions of general interest to the motorist will de answered dy Mr. Clough in this column, space permitting.

Canada sold nearly twice as many cars in New Zealand as the United States did and quad- rupled its own 1922 business. Figures submitted by Trade Com- missioner W. A. Beddoe, from Auckland, Zealand imported 12,359 motor cars, of a total value of £2,073,297. Of these 7,380 cars, worth £966,384, came from Canada; 4,309, warth £854,171, from the United States, and 496 cars, worth £208,953, from Great Britain. Canada sent 925 motor lorries, busses, etc., to New Zealand during the year. The value of them was £81,689. The United States sent 437 and Great Britain 217. The total imports of this class of vehicle into New Zealand in 1923 wag three times that of 1922, Of moior cars New Zealand imported near.y four times as many as in 1922. TO HALT ALL TRAFFIC AT RAIL CROSSINGS New Plan to Be Tried Out on Long Island As Experiment, Motorists everywhere will watch with interest the new system for the protection of level crossings which will this month be inaugurated by the Long Island Railway. Under the new rule, just adopted evecial trafic men will be employed who will blow a whittle as a warning to the drivers of automobiles, motor trucks mot.reycles, bicycles, horse- drawn vehicles and pedestrians to halt at public highways which in- tersect the railroad tracks at grade. This will mean that all who pro- ceed over such a crossing will be compelled to come .to a complete standstill before doing so, which in case of the approach of a train should render this system of keep- ing the tracks clear of other traffic effective. DON'T NEED BIG INCOME TO PURCHASE MOTOR CAR While 10,250,000 passenger automobiles were registered in the United States last year, no more than 4,000,000 persons filing in- come tax reports reported an in- come of more than $2,000 a year. This indicates there are 5,000,000 or 6,000,000 persons earning less than $40 a week that have bought motor cars, and probably bought them on the installment plan. Carburator Float Test. A defective metal float chamber of the carburetor can be tested by immersing it in a bowl of very hot water. If bubbles rise, it is sure indication that there is gasoline in the chamber. Make the hole slight- ly larger, and also punch another very small hole on the edge of the float, and shake out the gasoline.

In keeping with the policy of constant improvement, ef- fective measures have been taken to minimize vibration. Applied to the body, engine, clutch, brakes, and other vital units, these refinements add immeasurably to the comfort of travel over boulevards and country roads. The effect is so pronounced, in fact; that it is entirely fit- ting to classify smooth per- formance as one of the out- standing attributes of Dodge Brothers Motor Car. M. OBERNDORFFER 124 CLARENCE STREET, When it is empty, drop a small spot of solder on holes, but be very care- | ful not to use too much or the bal- ance of float will be upset. Be care- ful not to use very much heat, or it will open up the seams in the float and ruin it. If the float is made of cork, the probability is that it is water-logged. In that case, dry it out in an oven with a very mild head, then give two. or three coats of shellac. Back-firing in the carburetor may be another indication of poor seat- ing valves. A wise motorist will keep every- thing tight, and drive his car at speeds where the engine will not cause vibration, A quivering car helps to chip off paint and enamel.
