Cleaning Out Car
 bon and Grind '... ing: Valves

 Too much oil in the crank case: worn pistons and rings; too rich mixture; faulty ignition; very poor grade of gasoline; cheap lubricating oil cause premature carbon deposit, the effects of which are loss of power, poor gasoline mileage, waste of oil, dirty or fouled spark plugs, weak compression, overheated or pounding motor, and scored cylinders
 Of course, carbon forms in any and all internal combustion motors, but the process is slow if the motor is in good condition and given the proper attention.
 When we undertake a job of clean ing out carbon and grinding valves, the process is n follows:
 | All water is drained from the radi- iG,or, and upper radiator hose is loosaned from it's connection with cylinder head Cylinder head bolts are then loosened and cylinder head removed from motor block.
 Valve doors or side covers are re- moved from motor and valve seat pins are removed, after which the valves are taken out.
 All carbon is scraped and cleaned from top of cylinder block, heads of pistons, etc.
 The valve seats in cylinder block are thoroughly gone over and if found to be pitted or worn out of true a special seat reamer is used to form new seats for the valves.
 The valves are examined and if true are then ground and fitted until per- feet seat is obtained. The valves are now timed up to piston travel, thereby assuring powerful and even running motor.
 The valve springs are then tested for too little or too much tension. Those springs not meeting the proper test are discarded and replaced by springs of even tension.
 The valve springs, "valves valve doors cylinder head, etc, are then as- sembled. The radiator is again con- nected up with cylinder head and fill- ed with water.
 Spark plugs are inspected, thor oughly cleaned and points adjusted.
 The motor is now started up and given the final test, after which it is ready to be turned back to owner,
 Our labor charge for this work is S3,5O, necessary parts extra.
 We use Genuine Ford Parts exclu- sively.
 Cleaning out carbon and grindi, valves will give the motor more pc CT, but ignition system must be good condition to insure a compl. and smooth running job. If you h9 not had Special Tune-Up'' some time. it would be advisable have one in conjunction with the mer operation. We have a com tion labor charge covering both ations of S4.50. Parts, if any, To be more free from carbon trou bles. observe the following:
 Have just the proper amount of oil in crank case. Open upper pet cock under motor and pour oil into breath CT pipe until oil just drops out of up- per pet cock. This is the correct oil level, and if you will take the precau- ton to check up on your oil supply every few days and maintain this level you should have no trouble as far aa too little oil is concerned Too much oil helps to form carbon-too little oil will cause excessive wear and burn out bearings. And while We are on the subject of oil, let US caution you: use good oil, Cheap ,pil is high at fany price. | If it develops. that your piston and rings are worn; take steps to have this remedied at once
 Have your carburetor adjusted SO Ithat mixture will not. be too rich. which not only hastens. formation of carbon but is wasteful of gasoline,
 Keep your spark plugs clean. Keep your timer cleaned and. oiled. Keep lyour wiring free from oil and replace kany broken wires. Have your vibrator points adjusted from time to time. l It is not always possible to avoid getting poor gasoline, but thesexercise of care will tend to at least reduce the lchances.
