Supplement of the Canadian Statesman. April 28'l 1976 3 Thorough tune-up is needed when aim is best performancëe Better gasaline mileage, more pep, surer starting are ail benefits ta be de- rived from. an engine tune- up. But ta get the maxi- mum the service offers, Champion Spark Plug Company suggests the me- torist shauld became 'ac- quainted with what a good' tune-up is and insist on receiving ail ingredients. Bef are having a tune-Up performed, make sure that the engine is in condition to benefit. The engine. shouid be in generally gaad mechanical condi- tion, criticai parts lubri- cated, the cooling system and exhaust functioning. An engine with burned valves, worn or damaged piston rings cannot be tuned properly until worn or damaged parts are re- paired. Sa it is important that cylinder balance and com- pression 'checks be per- formed ta heip detect any seriaus malfunctions. Ignition Systemn Basios of any tune-up include changing of spark plugs and points and con- denser in cars so equipped. Some cars have electronic ignition wtotpoints and condenser. Checking ail ighition components is recommended and if re- placement of ,items that came in sets (such .as plugs and plug wîres) becames necessary, then change the whole set. Installing one or two plugs or wires is 'faise ecanamiy since if several units need repiacîng then their mates will probabiY wear out soon. 1Carburetion The carburetar, whieh delivers, the proper mix- ture of air and fu7el ta the intake manifold, should be checked for ieaks in the gasket-area. Excessive dirt and varnish, improper choke and faulty linkage aiso are passible carbure- tor defects. Related areas such as fuel pump, air filter, fuel line and fuel filter should be checked as part of the tune-up procedure.. Emission control system Variaus emission control devices have been intro- duced into cars in the past f ew years. Each of these devices must be checked ta make sure it is praperly functianing for best pe rf ormance, depend- ability, economy and re- duced exhaust emissions. Sa, when yau see an ad for a tune-up at an unbe- iievably 10w price, check what you are getting for that price. Does it include parts or merely labor? Is the shop equipped with devices like- engine oscilloscopes, ex- haust gas analyzers and other sophisticated equip- ment?, A good tune-up that will save 'you money and help your car ta top perform- ance won't came cheapiy. But, a cheap tune-up -is no bargain. EPA asks action to eut vapo rs from Gasaline vapors that en- ter the atmosphere fram filling station gas pumps accaunt for six per cent of ail harmful emissions in large population areas, according ta the U.S. Environmentai -Protection Agency. The EPA has proposed action ta limit the amount of vapor in the air in eight speciflc areas. Contrais of certain fiiiing stations ,wauid be imiposed in Baiti- m6re, Boston, Denver, Los Angeles, Newark, Sacra- mento, Washington, D.C. and the San Joaquin 'Val- ley in C alifarnia. Unider the regulations, stations pumping more than 10,000 galions per month would have ta pro- vide for recavering vapors. Final compliance would be required by May 31, 1977. To meet proposed stand- ards, speciai pump nozzles gas pumps and hases would be used. These would return vapors from the car's tanks toaa special underground star- age tank. The EPA esti- mates some 37,000 gas sta- tions in the eight areas would be affected. Costs required ta instali equip- ment wouid mean about a haif-cent extra per gal- lon for the custamer. Don't kIi'caL' Sometimes it isn't "busi- ness as usuail" when serv- icing a new model car equipped with a catalYtic converter. Take the mat- ter of using a carburetor cleaner-or other fuel addi- tive. Unless these sub- stancçes are used in a cer- tain prescribed way, they could cause damage ta the converter, rendering it useiess.
