| old shoe, and if it is necessary to l place additional patch in the old shoe | to cover blowout.
 What would you recommend to be
 used to stop buzz in my differential? :? l use Dixon 677 and 6SS fibre mixed
 but it does not stop the buzz.-N. L. W.
 Sections from an old case may be used to advantage in case of blow outs. The edges of the section should b" carefully bevelled to prevent injury to the tube. 1t is also advisable to remove the tread from the section in order to reduce the thickness. It i' hardly practical to install an old casing within an old casing The buzz in the differential may be due to the gears being meshed too close to- gether This should be eliminated by proper adjustment. providing the gears are not too badly worn.
 Motoring Department: On my one cylinder Cadillac car I am constantly bothered with plugs smoking up and becoming coated with carbon, so that they ground. Please advise in your Auto Columns. how to over come this difficulty.-W. M. R.
 This car is very old, and the cylin- der is probably worn to such an ex- tent that too much oil gets into the combustion chamber. In order to eliminate this trouble you will prob ably find it necessary to have the cylinder rebored and new piston rings fitted. Excessive carbonization is due to an imperfect combustion of the mixture. Too much oil will cause this trouble. If you do not care to entail the expense of reboring the cylinder you might try using oil of a heavier grade and also cut down the supply. An over-rich mixture will also cause carbonization. Keep the mixture as lean as possible and carry the sparks as far advanced as pos sible.
 Motoring Department: 1 find that after running my car an hour or so 1t begins to jerk and miss The motor doesn't seem to pull at all. Stopping the car, I find the motor is running good. Leaving the car stand minute and then starting again I find , it will run fine for about twenty minutes and then the same thing will happen again.-R. H.
 
 most of the time and balks occasion ally is sufficient proof that there is nothing seriously wrong. Perhaps there is foreign matter in the gaso- line pipe line which at times flinders the proper flow of gasoline to the car buretor. A little water in the car buretor would also produce the same result
 If the valves have not been cleaned for a long time, it is possible that they may be gummed and occasional ly stick. It appears. however. that the annoyance is more than likely due to foreign matter in the carburetor and pipe line.
 Motoring Department: Please answer the following and oblige: My Stover gasoline engine has the make | and break hammer type ignition sys- tenn. Same failed to work after thor oughly cleaning and scraping the con- tact points. I have removed each part thoroughly cleaned same, re- placing new mica or isinglass on the stationary side after replacing same for trial. It made few good sparks by constantly trying same. sparks irregular, large and small, finally quitting. Can same be repaired with out new plug? I am using wet bat teries with spark coil; same are gooo. Respectfully, READER.
 If any of the plugs are defective it will be necessary to replace them. One defective plug will upset the
