"Sam Snedecker and Pete Bailey, I guess," he murmured. "Well, they're a trio pretty much alike. The farther off they are the better I like it."
Tom once more gave his attention to his own boat. He was going at a fair speed, but not the limit, and he counted on reaching home in about a half hour. Suddenly, when he was just congratulating himself on the smooth-running qualities of his motor, which had not missed an explosion, the machinery stopped.
"Hello!" exclaimed the young inventor in some alarm. "What's up now?"
He quickly shut off the gasoline and went back to the motor. Now there are so many things that may happen to a gasoline engine that it would be difficult to name them all offhand, and Tom, who had not had very much experience, was at a loss to find what had stopped his machinery. He tried the spark and found that by touching the wire to the top of the cylinder, when the proper connection was, made, that he had a hot, "fat one." The compression seemed all right and the supply pipe from the gasoline tank was in perfect order. Still the motor would not go. No explosion resulted when he turned the flywheel over, not even when he primed the cylinder by putting a little gasoline in through the cocks on the cylinder heads.
"That's funny," he remarked to himself as he rested from his labors and contemplated the "dead" motor. "First time it has gone back on me." The boat was drifting down the lake, and, at the sound of another motor craft approaching, Tom looked up. He saw the RED STREAK, containing Andy Foger and his cronies. They had observed the young inventor's plight.
"Want a tow?" sneered Andy.
"What'll you take for your second-hand boat that won't run?" asked Pete Bailey.
"Better get out of the way or you might be run down," added Sam Snedecker.
Tom was too angry and chagrined to reply, and the RED STREAK swept on.
"I'll make her go, if it takes all night!" declared Tom energetically. Once more he tried to start the motor. It coughed and sighed, as if in protest, but would not explode. Then Tom cried: "The spark plug! That's where the trouble is, I'll wager. Why didn't I think of it before?"
