MANY car owners recognize the value of having the car overhauled before the inception of the active riding season when climatic conditions are not favorable to the continual operation of the car. In those portions of the country where cars may be kept in operation all the year round, a certain time each year should be set apart for giving the car a thorough looking over with a view of determining the points where depreciation exists, and the best methods of remedying the defective condition. The wise motorist realizes that this work of restoration is absolutely necessary. if continued satisfactory service is to be expected from the car. The motorist who shuns the expense of having the machine looked over and who operates it as long as the various parts function, is generally the one who is loudest in the condemnation of the automobile. In this chapter, the writer proposes to discuss the various. steps incidental to overhauling gasoline engines of various types.
