gasoline and water cut the grease1 f so, how should it be applied?
 No doubt the addition of gasoline to the water in connection with sponging the car will efficiently aid ill the cut ting of the grease. It would have to be applied either in spray or sponge. as these are the only two practical methods of mixing it ill such way that it would combine closely enough to form suitable mixture for clean ing. Kerosene is also frequently used in this manner with success.
 | have car with two speed rear axle. Whenever go down hill or over a bump with the clutch out 1 hear a rattle. What is the cause of this?
 The rattle you mention is probably from the idle pinion on the rear axle. In this axle there are two bevel pinions constantly in mesh. and one of these is always running idle, and the partfc- ular gear which is delivering the pow CT from the motor depends upon the position of a dog clutch. When the car goes over rough spot with the clutch out there is tendency for the drive shaft to revolve at an unequal rate of speed. due to the inequalities of the road, with the result that the idle pinion is alternately thrown back ward and forward against the bevel gear, with which it meshes, thus 'mak- ing a rattle. There is always certain amount of back lash in these gears. and the amount of noise will naturally depend upon the extent of this play. There is nothing serious about this. as the noise occurs only at rare intervals. and then is not the indication of trou. ble.
 Will you kindly tell me how to bend the gasoline and other tube lines in short arcs without the pipe f'attening?
 Copper tubing of small diameter can he readily bent into short curves by melting rosin and pouring it into the tube. When this becomes cold it solidi. lies within the tube, and the tubing can be bent like Il piece of solid cop per After the desired bend has been obtained the rosin can be run out by heating the tube with blow torch. Another method sometimes used is to fill the tube with sand. but the rosin method gives the better results.
 Why has a rotary valve engine five or seven cylinders instead of four, six or eight7 1a AliA-s Ai55f- *5 ~'
 The odd number of cylinders gives more even torque in a rotary cylinder engine Questions of balance make an even number of cylinders preferable in the conventional type of motor.
 Is it possible to start the motor in a car when the self starter fails to work and the crank is missing? ss #
 When the starter fails and the hand crank is not available the best method of starting the motor is to jack up one of the rear wheels so that it will turn without touching the ground. Then place the gear shift lever in high, and q few turns of the uplifted wheel will start the motor. Place the gear shift lever in neutral before letting down the jacked up wheel or you will have runaway on your hands, or at least the motor will stall, and you will have all your work to do over again. Prop. erly done the entire operation takes only few moments.
 What are the common causes for a motor missing fire?
 Missing fire may be caused by an overrich or too lean mixture by poor valve adjustment, inaccurate valve or ignition timing, leaks around the spark plugs, cylinder plugs. manifolds, etc., loose ignition wires, weak magneto magnets, water in fuel. faulty spark plugs or those with poorly adjusted electrodes, carbon deposits in the cyl finders and overlooking.
 When 1 throttle my car down on high gear 1t begins to jump and jerk as though the clutch were slipping. The clutch is all right, however. What can be the trouble?
 AHN J'AAPiA5 'LN JCAAIuS dStlOu lS probably due to the motor missing fire. caused either by poor ignition or faulty carburetion at low engine speeds. Mix lures may be too lean or too rich. there may be leaks in the intake manifold. or the spark plug points may be too far apart or too near together. Look at them first and see that they are spaced thirty-second of an inch apart Then see that your vibrators are ad justed If the trouble is still in evi- dence your magneto magnets may be weak and require recharging.
 What is the advantage or disadvan- tase of the cantlever spring in regard to the three quarter elliptic?
 The main advantage of the cantilever spring over the three-quarter elliptic is that it will give the same carrying capacity with the proper flexibility with considerably less weight. Anoth- CT advantage lies in it's slow period of vibration and the ability to eliminate rebound to a great extent. The weight of cantilever is nearly all unsprung
