Worn Insulation Check the insulation of cabtes and wiring on your car now. Breaks in the insulation are likely to ea " S short circuits, and possibly set your car on fire. Besides, in the ram the cars with poorly insulated electrical circuits are the ones that wont start when they get wet. Engine Valve Adjustment High compression must he kept high. This is not possible if valves are permitted to deteriorate. In a high-compression motor the valves are subjected to tremendous heat, it ■ they are adjusted too closely they will burn beyond all hope or re pan. On the other hand, if they are allowed to become too loose, hot gases escaping over the valve seats will j destroy them.
