 Motoring Department, the Herald What is the proper way to clean a spark plug?-C. H. Jordan.
 Most people believe they have cleaned a spark plug properly when they have cleaned the spark gap points The proper way is to remove the porcelain or insulator and clean 1t thoroughly. The carbon deposit on the porcelain permits a short cir cult between the center rod and the engine metal. If the insulation is not cleaned, then the spark plug is as inefficient as though not cleaned at all.
 Motoring Department. the Herald - would Nike to know the difference between advance and retard on a high tension magneto, if 1t has any thing to do with the magneto when you advance the spark or retard 1t. A friend says that when the spark is advanced 1t makes the magneto stronger. say that the magneto is the same with the spark. either retard or advance.--A. N. Weeks.
 Advancing and retarding the spark on mngneto simply makes and breaks the primary circuit by means of the circuit breaker sooner or later, as re- ouired. The maximum voltage is obtained when the armature breaks away from the pcae. When motor is travelling at high speed it Is nec- An hrn r. lyl1 1f- ly in order to obtain the best re- suits.
 If the primary circuit Is not broken until the armature has left the pole a weak spark results. Since there Is more or less lag 1t is necessary to have an advanced action to the cir- cult breaker in order that the max imum spark efficiency may be ob- tained at the time when the arma- ture breaks away from the pole. Especially is this desirable when a motor is travelling at high sped.
 Motoring Department, the Herald Please explain in detail the cause and remedy of the trouble with n gasoline motor when the cylinders are flooded and will not start. I mean to inquire why 1t is so difflcult to start an engine after the cylinder has been overprimed and wish to know how one can tell when it is overprimed, and what is the quick est way of rcmedying it.--T. H. Lit- tie. s* 3 A great many persons make the mistake of priming the motor too much. Too rich a mixture will not ignite any more readily than poor mixture. v Raw gasoline will not ex- plode but simply burn slowly. Most carburetors have a prining lever at tached 5, If this lever is pulled once or twice it is sufficient to fix the mix ture for starting. When priming the cylinders direct from the petcocks very little gasoline should be insert- ed. The average petcock has a cup which, if filled is sufficient to prime the cylinder If too rich a mixture Is drawn into the cylinder the pet cocks should be opened and the mo- tor cranked few times in order to free the cylinders of the rich mix ture. If the petcocks are then closed and the motor cranked without prim- ing 1t should start without further trouble.
 Motoring Department, The Herald During the past winter experienced lot of trouble with the tire chains on the rear breaking and hitting the lenders. Once the chain caught in the right hand rear fender and alm ost ruined it. Whenever the car would go over a heavy bump in the road the lenders would seem to go down and hit the tires. This never hap pened before. The springs seem to be in good condition, but the lenders now are in bad shape. I am about to put on new lenders. and would like
