EASY STARTING

WITHOUT USING THE CHOKE. Prompted by an article which appeared in a recent issue of the Sydney Morning Herald motoring columns, a reader has forwarded the following letter to the paper, in which he explains the method he adopts to ensure quick starting of a cold engine. The prac'tice referred to below is one that is followed by many car owners, and, in the opinion of competent engineers, it is preferable to that of flooding the carburetter and using the "cholce" when the engine is cold. While it may be argued that it is undesirable to leave a heavy charge of mixture in the cylinders overnight, because petrol might leak past the piston rings and so contaminate the oil in the sump, such a contingency need only be considered when there is much cylinder wear. The correspondent writes as follows: "In your article on 'Draining the Crankcase,' you state that 'excessive

use of the choke when starting a cold engine tends to contaminate the oil in the crankcase.' For sevsral years I have been able to start my car (a 1927 Pontiac) without using the choke and without flooding the carburetter. "When -I drive into the garage after having hesn out for a run, I spe^d the engine up slightly hy touching the accelerator and immediately switch off. Just as the engine is stopping (the sucking noise in the carburetter indicates this) I pull out the choke rod, thus completely closing the choke. When I want to start the engine I switch on, push the choke rod half in, and open the throttle one quarter. As soon as il step on the selfstarter the engine fires. I have used this method for several years, and not once has the engine failed to start immediately, even though at times the car has stood in the garage for two weeks without heing used. "Any small amount of petrol drawn into the induction pipe by closing the choke while the engine is still running is immediately vaporised by the heat of the induction pipe, whereas, by waiting until one is going out before choking the carbureeter, unvaporised petrol is drawn into the engine.
