“That's funny,” Foster observed weakly.
On the level Bud went into neutral and pressed the self-starter with a pessimistic deliberation. He got three chugs and a backfire into the carburetor, and after that silence. He tried it again, coaxing her with the spark and throttle. The engine gave a snort, hesitated and then, quite suddenly, began to throb with docile regularity that seemed to belie any previous intention of “cutting up.”
Bud fed her the gas and took a run at the hill. She went up like a thoroughbred and died at the top, just when the road had dipped into the descent. Bud sent her down hill on compression, but at the bottom she refused to find her voice again when he turned on the switch and pressed the accelerator. She simply rolled down to the first incline and stopped there like a balky mule.
“Thunder!” said Bud, and looked around at Foster. “Do you reckon the old boat is jinxed, just because I said I could drive her as far as she'd go? The old rip ain't shot a cylinder since we hit the top of the hill.”
“Maybe the mixture—”
“Yeah,” Bud interrupted with a secret grin, “I've been wondering about that, and the needle valve, and the feed pipe, and a few other little things. Well, we'll have a look.”
Forthwith he climbed out into the drizzle and began a conscientious search for the trouble. He inspected the needle valve with much care, and had Foster on the front seat trying to start her afterwards. He looked for short circuit. He changed the carburetor adjustment, and Foster got a weary chug-chug that ceased almost as soon as it had begun. He looked all the spark plugs over, he went after the vacuum feed and found that working perfectly. He stood back, finally, with his hands on his hips, and stared at the engine and shook his head slowly twice.
Foster, in the driver's seat, swore and tried again to start it. “Maybe if you cranked it,” he suggested tentatively.
“What for? The starter turns her over all right. Spark's all right too, strong and hot. However—” With a sigh of resignation Bud got out what tools he wanted and went to work. Foster got out and stood around, offering suggestions that were too obvious to be of much use, but which Bud made it a point to follow as far as was practicable.
Foster said it must be the carburetor, and Bud went relentlessly after the carburetor. He impressed Foster with the fact that he knew cars, and when he told Foster to get in and try her again, Foster did so with the air of having seen the end of the trouble. At first it did seem so, for the engine started at once and worked smoothly until Bud had gathered his wrenches off the running board and was climbing it, when it slowed down and stopped, in spite of Foster's frantic efforts to keep it alive with spark and throttle.
