Gus Puts the Heat on an MG Barnses was a big wheel at the local bank, Gus Wilson was just finishing up a brake adjustment when Stan Hicks, his young helper, came back into the repair shop. "The foreigners sure are taking over," Stan said. "Foreigners?" "Yeah, those snazzy foreign cars. Bet Ive gassed up half a dozen this morning." "Oh, sure. Didnt you know about the road race the sports-car boys are holding out on the Mill Saturday? Theyll probably be coming to town from all over." During the next few days, the Model Garage looked almost like a petrol station on the Continent. By the time Friday afternoon came around, Gus had poked his head under the hoods of more Healeys, Allards, Romeos, MGs, Jaguars and Ferraris than he had ever even seen before. It wasnt until late Friday that Gus was able to take a breather. "Well, Stan," he said, "looks like the rush is over. Im going to call it a day." But Gus had no sooner got the words out of his mouth than he heard a car pull up. "Sounds like another foreigner," said Stan. It was a trim, little black MG with the top down. The big man driving it made it look even smaller. The big man driving it made it seem even smaller. "Something we can do for you?" Then Gus did a double-take. The man at the wheel bore a remarkable resemblance to J. B. Barnes, president of the local bank. Of course it couldnt be Barnes. Gus looked closer and his jaw dropped. Maybe it couldnt be, but it was. Gus had banked at Barness institution for several years and he had serviced the financiers imposing limousine regularly, but he never expected him to turn up in a leather windbreaker and old cap, driving a midget car. Grinning, J. B. was extricating himself from the drivers seat. "No, youre not seeing things, Gus," he announced jovially. "And its not as funny as you might think. Used to be a scorcher in my younger days. Drove a Stutz Bearcatthere was a car for you! Even did a bit of dirt-track racing." "No kidding," Gus said admiringly. Things began to add up. "Say, Ill bet youre going in that road race tomorrow." "You guessed it, and thats why Im here. I had a chance to pick up this MG at a bargain the other day and couldnt resist it. Doc Tandy says I ought to get my mind off business once in a while anyway andwell, I thought I might as well try my luck tomorrow, just for fun." "Good for you. But whats wrong with the car?" "Well, this afternoon when I made some trial runs over the course, I couldnt coax much more than 65 out of her. On the straightaways, the rest of the boys were going by me like I was anchored." "Drive her into the shop," said Gus, "and well have a look." When Barnes had parked his little MG in front of Guss bench, Gus climbed into the drivers seat and pushed down slowly on the gas pedal. At low speed it ran fine, but when Gus gave it the throttle, the engine seemed to get sluggish and mushy, as if it didnt want to take the gas. "Could be the timings off, or you may have a bum carburetor," said Gus as he checked the ignition system carefully. But a timing check showed nothing out of line. Then he went to work on the carburetor. Again he found nothing. The fuel pressure was up, the float level was right, and nothing seemed to be blocking the jet or the fuel lines. "Any other symptoms, besides that sluggishness?" Barnes thought for a moment. "Well, she seems to run a little on the warm side," he said finally, "but I dont think she overheats enough to cause any trouble." "How is she on gas?" "Well, its hard to tell in the short time Ive had her, but offhand Id say she uses more than she should." Gus said nothing as he climbed back into the car and started the motor again. After tromping on the accelerator several times he climbed out, put his head close to the engine block and began racing the motor by working the throttle lever on the carburetor. "H-mm, thats funny. Sounds like theres a trace of a spark knock." He turned off the ignition and loosened one of the plugs. "Save your knuckles, Gus, if youre aiming to check for carbon," said Barnes. "That engine had a complete carbon job before I bought it. And those plugs are brand-new." "Hey," Gus said, with a grin, "youre knocking down my hunches even before I hatch em. Well, lets see if the vacuum analyzer can turn up anything else wrong." Stan wheeled out the portable analyzer panel and connected the vacuum tester. At idling speed, the needle on the gauge held steady at just about the right spot to indicate a fairly healthy motor. However, as Gus pushed down slowly on the accelerator, the needle began to get nervous. It would go up to a high reading, snap back to a low reading, and then climb back up. As Gus increased the engine speed, the needle snapped back closer and closer to zero and didnt climb back quite so far. "Well, you can chalk up one against Wilson," muttered Gus as he watched the needles gyrations. "Unless the gauge is a screwy as my last few hunches, about all that ails this car is a partially clogged exhaust system." Gus shut off the motor, walked to the rear of the car, kneeled down, and squinted into the end of the tailpipe. Then he probed around with a long-handled screwdriver. "You see, its badly coated with carbon and the mufflers probably even worse. These MG tailpipes are pretty small anyway, so the carbons been building up back pressure." Gus walked over to the corner, got his creeper and rolled it over to the car. "Whoa, Boss. Youll never make it," said Stan. "And it wont fit on our grease rack, either. Wait a minute and Ill have her up on screw jacks." When Stan had the jacks in place, Gus slid under. About a minute later he reappeared with a rather glum look. "The blamed exhaust system is all in one piece from the manifold right down to the tip of the tailpipe. No way of taking it apart. Id hoped maybe we could clean it out." "How about cutting it apart?" offered Stan. "No. I tell you what to do, Stan," Gus said after a glance at the shop clock. "Get right on the phone and call the Davis boys down in the city. They handle some parts for foreign cars. If they have an MG exhaust assembly, tell them to stay open a little longer and Ill pick it up." Stan disappeared inside the garage office as Gus slid under the MG again. "Anything I can do to help?" Banker Barnes sounded as worried as if a million dollar investment had gone sour. "Nope," came Guss muffled voice. "I just thought Id get a head start by disconnecting the exhaust from the hangers." Gus was working away at the last rusty bolt when Stans face appeared under the car. "No luck, boss. They havent any in stock and claim itll take at least a week to snag onto one." "Well, I guess that scratches me from the race," the big man said glumly as Gus reappeared from under the car. "Now hold your fire a minute," Gus kidded. "Stan, roll the acetylene welding rig out back while I unlatch the front end of this exhaust system." A few minutes later, standing in the open lot back of the garage, Barnes and Stan watched while Gus propped the MGs exhaust up on an old metal drum so that the manifold end was high in the air while the tailpipe was on the ground. Then he lighted the oxyacetylene torch, adjusted it to a medium-hot flame, and pushed the flaming tip into the end of the tailpipe. In a few seconds, dark gray smoke started to stream from the manifold end. Finally, when the tailpipe started to get cherry red, Gus reached down and shut off the acetylene and turned the oxygen full on. The smoke continued to stream from the other end of the pipe. "If Im lucky maybe well be able to burn the carbon out," explained Gus. As the three watched, the cherry red section seemed to travel up the tailpipe, along the muffler and finally to the manifold section. In about 20 minutes there was no more smoke. Gus shut off the oxygen. About a half-hour later, the MGs exhaust was back in place. Gus started the motor and it took the gas well. Evidently Guss burning-out process had worked. Then came the final proofa road test. The motor responded beautifully. On a deserted stretch of highway, Gus got the little car up to 85 without any urging. And on Sunday morning, at breakfast, Gus got his thanks. An item in the local Sunday paper read" LOCAL BANKER WINS IN ROAD RACE J. B. Barnes, president of the Empire Bank & Trust Co., took first place in his division of the sports- car road race held here yesterday. Mr. Barnes, virtually unknown in national sports-car activities, astonished a field of seasoned veterans by skillful maneuvering of his well-tuned MG around the sharp curves and 90-degree turns of the Mill Road Course. Hitting a fast pace right from the start, Barnes took an Early lead . . . |
