Show i MOST CAR AILMENTS MAY BE DETECTED BY WATCHING SYMPTOMS I J . .A. , Many of the most common motor car aliments can easily be detected and remedied If the car owner will learn 'to recognize the symptoms of trouble when they make themselves manifest Here Is a list of some of the difficulties motorists have to contend with, classified class-ified as to causes ami symptoms: Loss of Power Ignition Spark occurring oc-curring too late, spark control broken lor not properly adjusted; breaker not properly timed; worn, dirty, or poorly adjusted breaker points, weak spark due to defective wiring; worn or dim dlstrlbutOI carbon; battery In poor condition or poor connection to Kilter; , terminals Fuel Carburetor out of adjustment; adjust-ment; clogged atmosphere tube on acuum tank, carburetor controls broken or out of adjustment; choker button pulled out water in gasoline, broken or leaky vacuum line Motor Overhauling In bearings or climb i- pnor oil; gummy thin, or Inferior grade, oil lines clogged or rump not supplying sufficient quantity; quanti-ty; pump checks dirty, screens for separation of foreign matter clogged, or oil level in case too low: lack of compression due to leaky valves, Pro It en. stuck or worn rings, scored or worn cylinder; camshaft not properly timed; setting of push rod clearance. Motor and valves badly carboned. Water circulating system Clogged rad. iator or hose connections, temperature too lo (In case of winter driving.) M iflrlng Ignition Faulty spark . cracked porcelains badly carboned: or points not pioperly spaced; breuker points out of adjustment breaker arm spring too weak, defective wiring, low batter) charge; loos i points on breaker break-er arm or screw Fuel Carburetor out of adjustment inferior gasoline. Motor 1-ack of compression, stick-1 lr.g. pitted or warped valves, scored I or worn cylinders; defective piston ring. Founding Ignition Spnrk too early. Motor Carbon deposits In cylinder and on piston head, loose bearings tight piston due to lack of oil or lack ot cooling water; loose fly wheel; very looso piston (piston slap).

Smoke from the crank case breather tube indicates leak past the piston; look for worn rings rings stuck in srooves or scoring on cylinder walls A stiff motor will also cause this.
