D.J.D.—I have a new car and, in fact, it is not yet properly broken in. I have had trouble shifting gears easily, and would be glad of some advice. * * *

It would be a good 'thing to have a little practice in double clutching : until the transmission wears-in” enough to allow the gears to mesh , easily. Double clutching is quite easy. Start out with the car in low and press the clutch pedal." Instead of releasing the clutch after throwing the gear lever directly from first into second, as you usually do, release it \ for a second while the gear-lever is passing through the neutral position. Perform the same operation in going from second to high. Briefly the order is this—press clutch, pedal, move lever to neutral, release clutch, then immediately press pedal again and move lever to required gear and release. E.M.S.—Please tell me the proper pronunciation of the word spelled “Chrysler,” the name of a car. It is pronounced “Cry-slur.”

“Problem.”—The front near side tyre of my 1927 model Chevrolet, which has only done 1,500 miles, is wearing more rapidly than the others. It it showing this wear on the outside. I have jacked the wheel up and made a thorough inspection, but can find no reason for the heavy wear. The toein of the wheels is a-quarter inch. I know another owner of the same make of car experiencing the same trouble, and I would be glad if someone would enlighten me.

There are really five causes of excessive wear on front tyres, presuming that the tyre itself is O.K. (1) Wear on the near side tyre may be caused through the driver keeping well to the left of the road, particularly where the crown of the road is high, throwing the stress on to the near side tyre, which, in that case would show the most wear. This, however, is not a very usual case. (2) Tyres not correctly inflated will contribute toward excessive wear- (3) Wheels out of alignment will also contribute to excessive wear, but, as a rule, in this case both tyres usually wear away. (4) The axle having more set on one side than the other, giving more dish in the wheel. This is likely in the case under review, as the near side wheel is often rubbed hard against the curb by some drivers when pulling up, and it is possible that there might be a slight bend in the axle, caused by this, which will in turn, of course, result in excessive wear of that particular tyre. (5) Chassis out of alignment. This'may be the cause of the trouble, but it is very unlikely in the case under review.

A.S.—Kindly print the answers to the following questions in the Tuesday edition. I have a 1920 Buick touring. When parked on a hill the benzine flows out of the carburetter and floods the motor. When on level ground it stops. The hand brake cannot be used at any time on account of it sticking. By that I mean when applied it holds all right, but when you try to release it, it stays in place (locks). Would appreciate having these questions answered.

°u will have to park the car differently, as the benzine tank when higher than vacuum tank will cause benzine to flow from the carburetter. Remove rear wheels and clean emergency brake lining.

C.H.—I have a 1923 Chevrolet. Th« small speedometer gear driving the chain broke and I put in both new gears, but after driving about 1M miles it also broke (speedometer i* driven off th© universal joint). (1) What do you think is the cause? <2‘ Can I get gears to drive it off tn» front wheel? (3) How many kmperes should th© generator charge? (l) This probably was improperly installed. (2) Yes. (3) Bto 1--B.W O.—Will you please following question in next Tuesday “Motordom”: Have a 1923 MaxjeU sports model sedan.
