 Motoring Department-I have a 1910 car with a carburetor which will not run slowly. It seems to work we'll with the throttle opened to pull the car, but that is all. The engine seems to be in good condition otherwise. What do you suggest is the trouble ?-R. S.
 Many things prevent a motor from throttling to low speeds. Usually the trouble is in the carburetor adjust ment. At slow engine speed the air valve should be closed. If you feel the carburetor is right, then test for air leaks in the manifold. A slight leak in the manifold or one of the manifold gaskets will cause the trou- ble. The spark gap at the plugs should not exceed 1-64 of an inch. equal compression.
 Motoring Department, The Herald: noted in your Helpful Hints" re- gently reference to grease when used in the timing gears working through Into the crank case. This has
 
 which I had not been able to locate until I read your suggestion. The manufacturer of my car is no long CT in existence, therefore, will you please advise lubricant for the tim ing gears to which the fan is also geared that will not effect the oil in the crank case in the event of working through?
 Will you also advise with respect to heavy and light lubricating oils to be used in the crank case and how to determine the grade best suited to my motor?
 What effect in the operation or eff ficiency of a motor would result in using high grade cylinder oil that has been subject to hard freezing, say 15 degrees below zero in an un- warmed garage?- w. w.
 The New York and New Jersey Lubricant company, 165 Broadway, New York City, make lubricant termed "K-40" for use in the timing gears. This company claims that if this grease does work into the crank case and up into the cylinders it will not carbonize the cylinders any more than any ordinary high grade cylin- der oil.
 Would suggest that you use medium grade of 1ubricating oil in the crank case. If the motor is consid- erably worn it may be advisable to use a heavy grade. About the only way to determine this is to try each.
 If an oil has been subjected to zero temperature it is very apt to contain moisture. The character of the oil determines this to great ex- tent. Some oils absorb more moisture than others. If the oil is brought back to it's normal state of 7uidity by a gradual temperature it is less apt to contain moisture. The fact that there is little moisture in the lubricant should not materially affect it's lubricating qualities.
 Motoring Department. The Herald: We have 1910 Jackson, Model 35, which used to have a one-inch schebler Model "D'' carburetor About year ago we put on a one- inch Schebler Model "O' which works better up to thirty miles per hour, but that is as fast as we can make it go. With the old carburetor we had the car past forty-fve and 1 fifty miles per hour any time we wished.
 The car also uses too much gas with either carburetor, about eleven miles on a gallon. 1t is possible that the Model "O'' one-inch is too small. The machine otherwise runs fine and is in first class condition. E. M 4 party who has had experience with this model car advises that you (Continued on Ninth Page.)
