MOTOR & CYCLE.

A GREAT MOTOR CYCLE RIDE. The outstanding feature in Dip motor-1 ing world in Australia in November was • Mr. C. W. Korncrs' great motor cycle ride from Adelaide to Melbourne—sß9 | miles in 10 hours 35 mins. Since the | Dunlop Rubber Co. offered a gold watch j to the first motorcyclist, solo or side-car, who negotiated the overland roULc bel tween the two copitals iu 20 hours, there has been great rivalry as to who would secure the record and trophy. I After many attemtps by .various riders, the South Australian crack, C. Korner, succeeded in accomplishing the feat. His mount was a 7 h.p. Indian shod with Dunlop tyres. Adelaide was left at midnight, and Wellington (05 miles) reached under, two hours. Light rain rendered the clay-pans near Meningie very slippery, and Korner had a heavy fall crossing one patch, badly straining one of hia wrists, which caused him considerable trouble for the oalance of the journey. The Coorong was half covered in the dark, and despite this fact the 95 miles was covered in 4 hours 30 mins. Leaving Millicent, the i'enola-Casterton route was followed, the last-named town being reached shortly after one o'clock. The Western District course to Mel- , bourne was then taken, and his journey . completed in 25 minutes under the 2\, [ hours. Considering that Mr. Korner

weighs 14 stone, it wa3 a particularly fine performance over a strenuous course. The new record-holder is no new hand at speed work, for he has some particularly fine achievements to his credit, chief amongst which is his Australasian 24 hours motor cycle record of 851 miles established six years ago on a 3.} h.p. machine. Korner made a previous effort to establish a motor cycle record between Adelaide, and Melbourne as far back as 1913, but failed. Af the record figures for this journey have been brought under 20 hours, it automatically I cuts out the Diamond Medallion offered by the Dunlop. Company for the iirst rider breaking 24 hours.: As no rider was eligible to win both trophies, the donors have now decided that the medallion will be awarded to the rider reducing Korner's time. THE LONGS OF THE MACHINE.

The eurburettor may aptly be describ- | ed as the lungs of the engine, just as | a man in consumption cannot run well, "B so a car cannot travel if its breathing B apparatus is out of order. The symp- ' toms of bad carburation are, as a rule, very definite, Mislires, sluggish running, a uneven running, lack of power up' hills, A popping through ihe carburetter, and 1 foul exhaust are common symptoms, a When a driver has reason to think that | his carburation is at fault, the iivst I 1 point he should 3ee to is that the Fcefl S |is uninterrupted. To get at the 'eat of 3 : I the trouble he had better expose the jet, p j and then jerk the float spindle up and B

down sharply. If the spirit shoots | through, the. jet strongly, he may take | it that the feed is correct. If not he I must proceed with his investigations. | Possibly the jet may he wholly or par- \ tialiy choked, or there may be some 3 foreign particle at the bottom of the I jet which, when the engine is ru:wi"g, jj rises and partially chokes the jet, and f when it stops, drops again. Far tlus|i reason the carburetter should be car;:-lj fully cleaned out, and the bottom opened j so that water and dirt may be got rid j of. The jet should next be examined [ By looking through it, it is geno/ally 11 easy to learil if it is choked. The ob- |' strutting material can be removed by I means of a very fine wire, siuh as is I used for tying up flowers. If the feci is still feeble, the petrol pipe should

be disconnected from the carburet rer, I and tlie petrol tap turned on. If the i petrol does not flow freely, it- will be | at once evident (hat there is a partial | stoppage in the pipe. The pipe will | have to be dismantled anil Uie obslruc- J lion removed by menus of u long wive, or by blowing through with tin inflalor connected up to the end. In extreme eases we have known of the obstructing material being so caked that the pipe had to be placed in a forge-lire and tin? foreign matter absolutely burnt .mil, a. wire being then put through it to clean away the remains. Possibly the trouble may be found in the duct between the | petrol pipe and the float chamber. The j float, too, should be examined. If it .s | too light the float will rise too soon and shut the valve before the petrol has risen I high enough in the float chamber; or if it is too heavy or has become puncture:!, the float chamber will flood and the engine get too big a supply of spirit. The float, too, may not be evenly weighted. In this case it will get temporarily jammed, and thus affect the proper feed of spirit. The jet itself may be at fault; it may be either too large or too small, and this can be best diagnosed by experimenting with jets of different sizes. A, TEAMS RACE. A 24-hours cycle teams race was releently decided at Amsterdam (Holland), the winning pair being ,the Australian champion, U. Spears, and a Dutch rider j named P. Van Nek. In the full day j they covered 453 miles.
