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

Ma Dongxi was slightly startled: "Is it serious?"

It is not too uncommon for Ma Dongxi's motorcycle to encounter malfunctions. In the words of the car repairman, it is called "shooting off". It means that the gasoline deflagration in the exhaust pipe produces a loud noise, just like shooting off a cannon.

Ma Dongxi said: "It's just setting off cannons. Is it serious?"

Yi Yang shook his head: "Generally, the reason for firing is that the combustion in the cylinder is not good. The incompletely burned gasoline is discharged into the exhaust pipe and undergoes secondary combustion when exposed to high temperatures. If the firing is serious, the exhaust pipe may sometimes burst!"

Hearing this, Ma Dongxi couldn't help but become serious: "Is it so serious?"

Yi Yang said: "The Eight Classics of Zheng'er."

Zhang Bushou was stunned as he listened.

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

For a moment, Yi Yang didn't know how to explain it, so he had to change the topic: "Since the reason is that the gasoline in the cylinder is not burned cleanly, then it may be because the mixture is too rich and cannot be burned completely, or it may be that some combustion cycles are not timely.

When igniting the ignition, the mixture is not burning at all. Let’s follow this idea and check it carefully.”

Ma Dongxi said: "I had several repairmen look at it before, and they checked and found no problems."

Yi Yang frowned: "Have you checked?"

Ma Dongxi nodded: "I first checked and replaced the spark plug, high-voltage package, igniter, etc., and found no fault point."

Yi Yang asked: "Where's the carburetor? Have you seen the carburetor?"

"I checked, the carburetor oil level is basically normal."

Yi Yang couldn't help but fell into deep thought. After thinking for a while, he murmured: "Since the oil and electricity are normal, is there a problem with the gas distribution and timing?"

As he said that, Yi Yang picked up the tools from the ground. Unexpectedly, Ma Dongxi's toolbox was quite complete with accessories. He smiled slightly and began to check it in detail.

Ma Dongxi watched this little brother working with great interest, lit a cigarette for himself, and saw Zhang Bushou staring at Yi Yang with the same curiosity, 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, would you like one?"

Zhang Bushou didn't smoke much. He only smoked a pack of cigarettes without inhaling them into his lungs. He just thought this action was cool. But in this situation, taking one cigarette seemed to make him appear mature, so he subconsciously reached out.

Then, he received a slap on the hand.

"Ayo!"

Zhang Bushou immediately retracted his hand.

Ma Dongxi smiled and stuffed the cigarette into the cigarette case, "Minors are not allowed to smoke."

Zhang Bushou's hand hurt, but he was also very afraid of this uncle, so he could only raise his head aggrievedly and whispered: "You obviously gave it to me."

"Just pick it up if I give it to you?"

Zhang Bushou had mixed feelings and sighed deeply.

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

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

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

Ma Dongxi was stunned: "Got it?"

Yi Yang said seriously: "Actually, it's still on the circuit. I estimate that the real fault is that the connection line between the magneto trigger wire and the igniter has poor contact. Due to the poor contact, the trigger signal is intermittent and non-stop.

Regularly cut off the fire. After the fire is cut off, the unburned gasoline will be discharged into the exhaust pipe, causing gunfire."

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

The two of them worked together to check the magnetic motor in detail and found that the cause of the failure was exactly the same as Yi Yang described.

After finding the crux of the problem, it is actually a very simple thing to repair. Just reconnect the bad contact position and the fault will be solved.

Ma Dongxi inserted the key and started the motorcycle, and suddenly the exhaust pipe roared. He tried to twist the accelerator, and the motorcycle roared twice energetically, and nodded with satisfaction: "No problem. Thank you.

Little brother!"

Yi Yang smiled: "Nothing."

Ma Dongxi handed a business card to Yi Yang and said with a smile: "Little brother, I admire you very much. This is my phone number. If you have anything, please call me."

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

The boss of the Imperial City.

Yi Yang knew about the Imperial City Company. The owner of this company was later regarded as the richest man in Qinghe County.

This company started out as a KTV and bar. After gradually gaining some strength in Qinghe County, it caught up with the soaring housing prices and completed several real estate projects, and it suddenly rose to prominence.

Yi Yang remembered that fourteen years later, the Imperial City Company did not continue on the road of real estate, but once again transformed into serving the entertainment industry. It owned several hotels, a song city, a gym, and many storefronts.

, started a stable business of "sitting alone on Diaoyutai".

Although Ma Dongxi's assets are incomparable to those in online novels with tens of billions, he is already a dominant figure in a small county like Qinghe County.

I didn't expect that this uncle had such a big background.

However, Ma Dongxi's Huangcheng Company is still in its infancy, with only two KTVs and has not yet started to get involved in real estate.

But it will be soon, probably within the next two years.

Yi Yang carefully collected the business card and said to Ma Dongxi: "Okay, uncle, if I really get into trouble in the future, please don't try to trick me when I call you!"

Ma Dongxi smiled and shook his head: "How could that be?"

Ma Dongxi started to pack up the tools scattered on the ground, and said to Yi Yang: "You still have something to do, so go ahead and do it."

Yi Yang nodded, "Okay, uncle, we'll leave 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 around: "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 around and left, but stopped before they walked a few dozen meters.

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

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

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

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

Opposite, there is a yellow hair and three friends.
