Nut Retainer
 The simplest method of insuring that a nut shall not be loosened on it's bolt by vibration or other accident, is to take a punch and distort the thread just above the nut, after the latter has been fully run on. It is only necessary to distort the thread little and when the nut is run off with a wrench. it will restore the thread to its original shape.
 Cause of Leaks
 Many cars have wires or rods leading from the front of the radiator to the priming device on the carburetor These rods pass through one of the air passages of the radiator The tubes of radiators are made of very thin ma terial and in the course of a seasons s use, the prime rod in rattlng around through the vibration of the car, may cause leak that will be troublesome, The remedy is to insert a stiff piece of tubing in the air passage that holds the rod.
 Tire Valve Tip
 It is important to keep the tire valve and stay bolts drawn up tight, becausa | if they are not so maintained, water is very likely to get into the casing when | the car is being driven over wet roads. | Compression Loss
 It sometimes happens that an engine which runs all right when it is com paratively cold. shows a decided loss of compression after it has become heat ed. This is probably due to the fact that the valve stems expand with the heat and do not permit the valves to seat properly, hence the loss of com pression.
 Too Much Gas
 In case the motor fails to start after a generous amount of fuel has been supplied to it. the case may be one of too much gas and the remedy is to open the petcocks and turn over the engine briskly with the compression cocks open. This allows the engine to draw in enough air to form an explosive | mixture.
 Loose Bearing Bolts
 If clicking or tapping sound is heard coming from the crankcase in- terior it ought to be investigated at once Open the crankcase and examine all bearings and bearing cap bolts Should a broken bolt be found, all in that bearing should be renewed as the others are probably bent.
 Transmission Lining
 In fitting a new transmission lining in the Ford, the new lining should be let loose enough to permit the pedal to be thrust well forward and the en- zine to be turned over by hand with out difficulty. After the car has been operated for a few days so that the ,I lining has become set, it may be tight ened up by a single turn of the adjust ing nuts. If the bands are put on toe tight at first. there is constant friction with the drum, making it hard to turn over the engine by hand annd in addi- ton burning the surface of the lining. To Test Mixture
 Car owners. particularly new ones are often puzzled to know whether the mixture they areu sing is correct TC ascertain the correct proportions to be used. shut off the fuel at the tank and open the throttle If the mixture that is going to the cylinders is too rich the engine speed will increase as the level of the gasoline in the float cham Der is lowered since the operation Weakens the mixture considerably Il the mixture is suspected of being too weak, the float chamber may be flooded while the engine is running and if tho ehgine speeds up, it may be accepted as a sign that the mixture has not beer rich enough.
 To Set Magneto
 To set high tension magneto. tht nroper cylinder should be brought tt firing position both valves closed ant the piston at the top of it's stroke Thi may be ascertained by running a stou wire through a spark plug or petcocl opening or by looking at the valve and tappets. When the piston is in thi position, the motor must be backed one eighth of a stroke. at which position the spark should occur when the leve is fully advanced. The magneto inter rupter should be just about to opel and the distributor arm on the segmen corresponding to the cylinder, who's valves are both closed. In Usino Bolts
 Tn boiling materials of any sort to gethor do not try to pull the bol through if it sticks. by tightening u1 the nut. as this may strip tho threads Instead give the bolt smart tap t drive it into it's proper position an
