After listening to Ma Dongxi's description, Yi Yang sighed: "Uncle, your problem is not small?" This is a serious problem! ”

Ma Dongxi was slightly stunned: "Very serious? ”

Ma Dongxi's motorcycle, the trouble encountered is not too rare, in the words of the car repairman, it is called "fire". It refers to the occurrence of gasoline deflagration in the exhaust pipe to produce a loud noise, just like a cannon.

Ma Dongxi said: "It's just a cannon, is it serious?" ”

Yi Yang shook his head: "The reason for the general firing is that the combustion in the cylinder is not good, and the gasoline that is not fully burned is discharged into the exhaust pipe, and the secondary combustion is carried out at high temperatures. If the cannon is severe, it may sometimes burst the exhaust pipe! ”

Hearing this, Ma Dongxi couldn't help but become serious: "So serious? ”

Yi Yang said: "It's serious. ”

Zhang Bushou was stunned when he heard it.

Ma Dongxi was silent for a while, and suddenly had a strange expression: "You are so young, how do you understand these things?" ”

For a while, Yi Yang didn't know how to explain, so he had to change the topic: "Since the reason is that the gasoline in the cylinder is not burned clean, then, it may be because the mixture is too thick and cannot be burned, or it may be that some combustion cycles are not ignited in time, and the mixture is not burned at all, let's follow this line of thought and check it well." ”

Ma Dongxi said: "I asked a few repairmen to see it before, and they checked it and found no problems. ”

Yi Yang frowned: "Checked?" ”

Ma Dongxi nodded: "I first checked and replaced the spark plugs, high-pressure packs, igniters, etc., but did not find the fault point." ”

Yi Yang asked, "What about the carburetor?" Have you seen the carburetor? ”

"I've seen it, and the carburetor oil level is basically normal."

Yi Yang couldn't help but fall into deep thought, thought for a while, and muttered: "Since the oil and electricity are normal, is there a problem with the gas distribution?" ”

Saying that, Yi Yang picked up the tools from the ground, but he didn't expect that Ma Dongxi's toolbox accessories were quite complete. He smiled and began to examine it in detail.

Ma Dongxi watched with interest as this little brother worked, lit a cigarette for himself, and saw Zhang Bushou who was also staring at Yi Yang curiously on the side, and asked, "Little fat man, are you Yi Yang's friend?" ”

Zhang Bushou nodded: "Ah, we are good brothers." ”

Ma Dongxi smiled slightly, took a cigarette from the cigarette case, and handed it to Zhang Bushou: "Little fat man, have one?" ”

Zhang Bushou didn't smoke much, he only smoked a pack of cigarettes, and he didn't inhale his lungs, he just thought this action was cool. But in this situation, one after another seems to be very mature, so he subconsciously stretches out his hand.

Then, he received a slap on the hand.

"Ahh

Zhang Bushou suddenly retracted his hand.

Ma Dongxi laughed and stuffed the cigarette into the cigarette case, "Minors can't smoke." ”

Zhang Bushou felt pain in his hands, but he was very afraid of this uncle, so he had to raise his head aggrievedly and whispered, "Obviously you gave it to me." ”

"I'll take it for you?"

Zhang Bushou had mixed feelings and sighed deeply.

At this moment, Yi Yang put down his tools and said seriously: "I have checked, I have conducted a detailed inspection of the assembly of the engine valve mechanism, valve clearance and whether the valve is leaking, and I have not found any problems." ”

Ma Dongxi sighed: "If you really can't find a problem, forget it." ”

Yi Yang smiled slightly, "I already know where the problem is." ”

Ma Dongxi was stunned: "Got it?" ”

Yi Yang said seriously: "Actually, it is still on the circuit, I estimate that the real fault is that the magneto trigger line and the connecting wire of the igniter have poor joint contact." Due to poor contact, the trigger signal comes and goes, and irregular fire breaks occur. After the fire is broken, the gasoline that is not burned is discharged into the exhaust pipe, which triggers the firing of the gun. ”

Ma Dongxi's eyes lit up, "That makes sense!" ”

The two of them worked together and checked the magnetic motor in detail, and sure enough, they found that the cause of the failure was exactly the same as what Yi Yang described.

Found the crux of the problem, in fact, it is very simple to repair, reconnect the position of poor contact, and the fault will be solved.

Ma Dongxi plugged in the key, ignited the motorcycle, and suddenly the exhaust pipe roared. He tried to twist the throttle, and the motorcycle roared twice in good spirits, then nodded in satisfaction: "No problem." Thank you, little brother! ”

Yi Yang smiled: "It's nothing." ”

Ma Dongxi handed a business card to Yi Yang, and said with a smile: "Little brother, I appreciate you a lot, this is my phone, if you have anything, call me." ”

Yi Yang took the business card and looked at it, and couldn't help but be slightly stunned.

The boss of the Imperial City.

Imperial City Company, Yi Yang knows. The owner of this company later became the richest man in Qinghe County.

This company started as a home with KTV and bars, and after gradually gaining a certain strength in Qinghe County, it caught up with a wave of soaring housing prices, did several real estate projects, and rose all of a sudden.

Yi Yang remembers that fourteen years later, the Imperial City Company did not continue to move forward on the road of real estate, but once again transformed into the service entertainment industry, with several hotels, Song City, a gym, and many stores, and started a stable business of "sitting alone on Diaoyutai".

Although Ma Dongxi's assets cannot be compared with the hundreds of billions of bigwigs in online novels, in a small county like Qinghe County, he is already a dominant figure.

I didn't expect this uncle to be so big.

However, at present, Ma Dongxi's Imperial City Company is still in its infancy, with only two KTVs, and has not yet begun to get involved in real estate.

But it's coming soon, about the past two years.

Yi Yang carefully put away the business card and said to Ma Dongxi: "Okay uncle, if I really have trouble in the future, don't call me!" ”

Ma Dongxi smiled and shook his head: "How come? ”

Ma Dongxi began to pack up the tools scattered on the ground, and said to Yi Yang: "You guys are still busy, just go and get busy." ”

Yi Yang nodded, "Okay, uncle, we'll go first." ”

The two walked a few steps, and Ma Dongxi suddenly laughed again: "That's right, little fat man!" ”

Zhang Bushou shrank his head and turned back: "What are you doing, what are you doing?" ”

Ma Dongxi smiled slightly: "Don't smoke, little fat man." ”

Zhang Bushou nodded helplessly: "Oh." ”

Yi Yang couldn't help but laugh.

The two turned to leave, but before they had walked a few dozen meters, they stopped.

Around the corner, a few junior high school students happened to come out.

Ma Dongxi picked up the wrench on the ground, and when he raised his eyes, he saw the scene, with a curious expression on his face, lit a cigarette for himself, leaned on the motorcycle and quietly looked in that direction.

Zhang Bushou couldn't help but glance at Yi Yang,

Yi Yang raised his eyebrows, but his expression was calm.

On the other side, there is a yellow hair and three friends.

Huang Mao was slightly stunned when he saw Yi Yang and Zhang Bushou, then sneered and strode towards the two.
