PAGE TwC Autos Were Once A Luxury, But Now a Necessity “TROUBLE SHOOTER” Shows How to Locate and Correct any Automobile Engine Trouble By E. 1. SCOTT. This is the seventh of a series of apooteny ereperee and tiustrated articles shows Gutomobile driver how to locate any engine trouble How To Test Your Engine To Find Spark Plug and Valve Trouble Last week you were shown how to test the Ignition System while the engine is r g. We assume you have tested this, and found that it is all right, so now proceed to test the Plugs and Valves. 1, Take off all nuts from the tops of the Spark Plugs, but leave the wires resting on the Plugs. If you have quick detachable terminals on the Plugs this will not be necessary, so— 2. If you have a four or six cylinder engine, then lift off all Spark Plug wires BUT THE ONE _ON THE PLUG IN THE CYLINDER NEXT TO THE RADIATOR, taking care to ground the end of each wire as you take it off by laying it in contact with the metal cylinder As you take off each wire, you will notice that the engine slows down, so after you take it off, move the throttle lever up a notch to keep the engine running at a moderate speed. Now you have the en- gine running on No. 1 cylinder only. If Se. 1 cylinder fires regularly, replace the wire on No. 2 Plug, THEN remove the wire from No. 2 Piug. If No. 2 cylinder fires regularly, replace the wire on No. 3 Plug THEN remove the wire from 2 Plug. If No, 3 cylinder fires regularly, replace the wire on N Plug, THE! remove the wire from No. 3, {f No. 4 fires all right, then replace the wire on No. wire fr No. 4 Plug. wire on No. 6 and remove the wire from No. 5. If the engine STO’ when the wire is left on ONE PARTICULAR PLUG, then replace ALL wires and start the engine again and continue until you have tested the other cylinders. ff you have ‘an eight or twelve cylinder engine, it will not usually run on one cylinder only, so test each cylinder separately by opening the Priming Cocks just a little, until you hear the sound of the explosion. Do not open the Cock wide open, as you are not able to test as well as you can by oj ening it just a little. If the cylinder is firing you will hear a good “crack” and if you look down will see a flame. After opening up a Cock, take a wooden handled screw driver, then short the Plug by connecting the top of the Plug and the Cylinder with the metal part of the screw driver. This will instantly show you the difference in sound between a cylinder that is firing and one that is not. If the engine STOPS ONLY WHEN THE WIRE IS LEFT ON ONE PARTICULAR CYLINDER, or MISSES AN EXPLOSION NOW AND AGAIN ON ONE PARTICULAR CYLINDER ONLY, See A. if, however, the engine fires on EACH cylinder when tested separe ately or if it does not fire very regularly on ANY of the cylinders then— Get into the car and drive it along the road, noticing which of the following agrees with the way it performs— If the engine misfires at LOW SPEEDS ONLY NOT RUN SLOWLY WHEN IDLING, yet runs alright at speeds of 15 miles an hour and over, see article eight next week. If the engine misfires or hunts at MEDIUM or HIGH SPEEDS, or if it WILL NOT ACCELERATE or STOPS ALTOGETHER WHEN YOU TRY TO SPEED UP, then see article nine which will Sppear two wecks from today. 1, Take ont the Spark Plug and see that it is clean and that the gap is correct. It should be just a trifie LESS than the thickness of a WORN dime. If the Plug is covered with an OILY, BLACK GUMMY de- posit, and you have been keep- ing the oil in the crankcase at the proper level, and using the correct grade of oil, about the only cure is to have new Piston Rings fitted and the Valves ground in. If, however, the Plug is covered with a DRY BLACK deposit like SOOT, your Carburetor is adjusted too rich, have it cut down to run with a leaner mixture. If the Points are WET, you cither have a leaking cylinder head gasket or a cracked cylinder, which allows water to creep into the cylinder. One of the best ways to clean Spark Plugs, is to soak them in a mixture of alcohol and kerosene all night, then in the mornin, the garbon on the porcelain can be rubbed off with a piece oi rag. NEVER use emery cloth or sandpaper to clean the porcelain. [t has a highly glazed surface that is easily scratched. When the glaze hecomes roughened, it quickly oils up again. The points of the Plug and the metal parts can, of course, be cleaned with a piece of emery cloth. Examine the porcelain carefully to see if it is cracked. If it is then fit new Plug. If the Plug APPEARS to be all right, then screw out a Plug from a cylinder that you KNOW is firing regularly, and put it into the defective cylinder and test the cylinder again. If the engine now fires on the cylinder, it proves that the first plug, although it appeared to be all right, is defective and must be replaced. Ii, however, there is STILL no explosion then— 5 Ply, If No. 5 fires all right THEN replace the and remove the or if it WILL 2. Examine the Valves in the defective cylin- der to sec that the clearance (as shown in Article Five, No. 8) is correct. If all right, then— 3. Start up the engine and watch the action of the Valves in the defective cylin- der, to see if the bottom of the Valve Stem follows the top of the Valve Tappet. If the Tappet comes down and little later, the stem is stick- the Valve follows a ing in the guide, showing it has warped. If it is sticking try and free the Valve by squirting a little kerosene down the Valve Guide when the engine is running if possible.

If you have a detachable cylinder head on the motor, examine to see if the gasket is blown out at any point. If it is blown INSIDE the head it will affect the TWO cylinders between which it is blown, NEXT WEEK—ENGINE MISFIRES AT LOW SPEED OR WILL NOT RUN SLOWLY WHEN ID Ne eines LOWEST STORAGE IN CASPER Gas, oil and car greasing, axles, drive shafts and springs, passenger car and truck tires and tubes, chains, Ford parts and accessories.
