MOTORS AND MOTORING

'Sy "Clntch.")'.. Valve Removal. , . ■■ In engines having demountable heads ai-i valves in the heads the removal of v»lvi;s is a mutter 'of difficulty, unless o::.,?. has found out just the proper trick. '/■.;■.(.• head should' be laid on the bench, right side up, and tho compressor slip--pw; on, after which a wiro should be l'oslened. nbout the handle of the'com-pi-essor, and then be anchored to tho leg of-tjio-bench, or table-. Next lift up on. th<S handle; .this .presses the spring down, the lock may be removed from the fiteni very easily, and tho job is done, Locating a Leak. It is usually difficult to find just where a leak in the petrol tank lies, because thf fluid after escaping spreads all around oiuthe surface of the tank. When you encounter thie difficulty ivipo off all tho potrol, and then coat'| tho area vrith black gudgeon greaso. Tho petrol tleaking out of. the hole, will cat away this grease and mako detection of the leak very ■ simple. Looking After Tyres. Careful observation of the tread of a tyro is absolutely necessary to obtain maximum eilioieuoy.. . If the' tread is not.kept intact, dirt, water, and other injurious'substances gain access to the fabric and. depreciation reeults. If the minor; oute causpd by running .over glass, aharp pebbles, etc., are not taken, care of, the "tyre will gc.oiit of service pretaaturelyv A , little tyre putty will remedy many of these If large cuts or ragged tears are found they should be vulcaiiieed at onoe. A Point to Remember. In inspecting .the springs attention should be giv«i to the spring hangers and other subsidiary parts.

This relieves the shock so that iniuiy times it may not be noted by those riding.. . ■■ Tho dirt which collocts on the distributor consists generally of carbon and metallic particles, due to wear of the-sur-faces; Both these materials ore conductors of- electricity. ITrequently the. current, instead of following the proper path, as indicated by ' the ■ distributor arm, through the brushes to the sparkplugs, ' will wander off across these dirt paths, causing timing (rouble, nnd, perhaps, backfiring. The addition of & little pure flake graphite to the lubricating oil ,is often a help to motors that have'wen some wear. Only- pure motor graphite should be used- :It forme-on-the metal'surfaces, reducing weai and filling up scores'in tho cylinders; . ■:■ N Lignting-up time:—To-day, 7.15 p.m. Next' Friday, 7.7 p.m. ' '
