Outing . y test ofthe motor and its trial by its new owner;and dozens of other troubles and acci-dents may contribute to the poor per-formance of a power plant from whichgreat feats have been expected—andcan be obtained when the seat of the dis-turbance is reached and matters rem-edied. Secure in the belief that his motor isup to specifications because it runs,many an owner may be perfectly satis-fied with the performance of his newboat, when in reality he may not begetting two-thirds of the power and effi-ciency to which he is entitled. If hiscraft is guaranteed to maintain a certainspeed and he finally discovers that shefalls below this mark, the disgustedowner may be tempted to return the en-tire outfit to the factory—for the con-trast with his feelings when he was un-der the impression that he was gettinghis moneys worth will give him thesensation that he has been duped. Butto ship a boat or a motor back to thefactory entails correspondence, waitingand red tape galore and may result in. FIG. I. A MOTOR OF THE SOLID HEAD CYLINDER TYPE, WITH CYLINDER RE-MOVED IN ORDER TO REACH THE RINGS a boatless owner during the remainderof the season. The trouble may be dueto his own carelessness as much as toany neglect on the part of the manufac-turer, and it is to the owners interestat least to determine if he cannot remedymatters for himself. Assuming that the motor runs, let ussuppose that it does not develop thepower for which it was designed. Withgood gasoline and a fat spark, thisloss of power nine times out of ten willbe due to faulty compression. Powercannot be obtained without sufficientcompression in the cylinder, for it isupon this that the force of the explosiondepends and a leak allows this usefulenergy to escape and be wasted abso-lutely. The compression, of course, canbe felt by the resistance offered to turn-ing the flywheel when all valves andcocks in the cylinder are closed. Ifthere is more than a single cylinder, theone offering the least resistance is
