After Li Jieshi finished speaking, Zhao Yougui said, "Then there must be something wrong with the engine. Let's take a look at the fuel injector."

"Let's take the engine apart first."

Wang Haoran helped Zhao Yougui dismantle the machine.

First remove the engine and lift it onto a flat surface covered with plastic sheeting.

Then we started to disassemble the machine.

At the beginning, Li Jieshi didn't let Wang Haoran interfere, fearing that he would damage it.

He said, "Haoran, just help out here. It's hard for you to come help when you've just been injured."

Wang Haoran smiled and said, "Uncle Jieshi, just let me get involved!"

"I want to learn how to repair cars, so I don't have to bother the comrades at the commune's agricultural machinery station anymore, right?"

Li Jieshi nodded appreciatively: "It's good for young people to be motivated."

"Then be careful. Put away the broken pieces carefully so that you don't get stuck putting them back together."

Wang Haoran said: "Don't worry, I will be more careful."

So, Wang Haoran started to disassemble the engine parts with Zhao Yougui.

Gradually, Li Jieshi and Zhao Yougui felt something was wrong.

Wang Haoran dismantled the machine extremely quickly.

It was as if he understood this machine better than Zhao Yougui.

In the end, the two of them simply stopped and watched Wang Haoran perform alone.

After about twenty minutes, Wang Haoran completely disassembled the engine.

Single cylinder machine, disassembly is also very easy.

Wang Haoran checked the plunger and fuel injector and found no problems.

Li Jieshi also knows a little about agricultural machinery. He said, "The plunger and the injector nozzle were only replaced a few months ago. Could they be broken again?"

Wang Haoran shook his head and said, "These two parts are fine."

"I think it's very likely that this thing has eccentric wear, which prevents the oil spray from atomizing, resulting in insufficient oil supply and insufficient power for the tractor."

As Wang Haoran was speaking, he picked up the small steel ball inside the ejector pin and showed it to Zhao Yougui and Li Jieshi.

The two took a look and found that the small steel ball was indeed severely worn and slightly deformed.

Li Jieshi's eyes widened, with an expression of disbelief: "Haoran, when did you learn to repair tractors?"

Wang Haoran smiled and said, "I have read some books on tractor maintenance in the commune library. Today I tried it for the first time."

Upon hearing this, Li Jieshi said with emotion: "You are really a talented person! Why didn't you show it in the past?"

Zhao Yougui was still a little skeptical. He rubbed his face with the back of his hand and said, "Then let's go to the supply and marketing cooperative and buy a small steel ball to see if it works."

Li Jieshi waved his hand and said, "No need to buy, we have a whole box here."

Zhao Yougui said, "I'm afraid the model is wrong?"

Wang Haoran smiled and said, "Take a look and you'll know if it can be used."

Li Jieshi went to the storage room and got a box.

There are many small steel balls of various sizes hidden in the box with butter.

Wang Haoran had sharp eyes and searched with his hands, and soon found a usable one.

"This is it. Try putting it together and see."

Zhao Yougui shook his head and smiled, "If you really fix it, the commune's agricultural machinery station will definitely want you to come over. They are very short of people right now."

Wang Haoran said, "Stop talking nonsense, reinstall the machine first and see if it works."

He would never consider going to the agricultural machinery station.

In the past, Wang Haoran actually had many job opportunities, but he didn't leave.

At that time, the child was very conscious and really planned to stay in the countryside for 10,000 years.

But now Wang Haoran has even greater ambitions.

He needs a bigger platform to do things.

Therefore, he still felt that taking the college entrance examination was the most suitable path for him.

So, with the help of Zhao Yougui, Wang Haoran began to reassemble the tractor engine. Li Jieshi stared at him with wide eyes, and he was worried that there would be a lot of extra parts that could not be installed.

As a result, the installation was perfect.

Three people lifted the machine up and re-secured it.

Li Jieshi took the crank and started the tractor again.

I saw him pressing the engine cover with one hand and turning the crank hard.

After just two turns, the car started.

Starting a fire is nothing.

The key is to see whether the problem of insufficient fuel supply has been solved during driving.

Of course, now you can tell that there is no problem with fuel supply just by listening to the roar of the engine.

"I'll give it a try."

As Li Jieshi was talking, he jumped into the car, stepped on the clutch and shifted gears, then started circling in the yard of the brigade headquarters.

After driving the tractor around a few times, everything was back to normal.

Li Jieshi was so happy!

He stopped the car and turned off the engine, then strode up to Wang Haoran, patted Wang Haoran on the shoulder and said, "Haoran! Haha! You are such a treasure! I didn't expect that you would really fix it!"

Wang Haoran laughed and said, "It's like a blind cat meets a dead mouse. I just guessed it was right."

Li Jieshi shook his head and said, "You are too modest!"

“That’s what it’s all about!”

"From now on, if there are any problems with the brigade's tractors, you will be responsible for repairing them. Of course, don't worry, you will get the work points!"

The entire repair process actually took just over an hour.

After repairing the car, Wang Haoran and Zhao Yougui came out of the brigade headquarters together.

Zhao Yougui said: "Haoran, do you really plan to stay in the countryside for the rest of your life?"

Wang Haoran said: "I changed my mind."

“I want to go to college!”

Zhao Yougui smiled, shook his head and said, "You only graduated from junior high school, can you keep up with the university?"

"I think you can go to an agricultural machinery school and become a mechanical engineer or something after graduation."

"The captain appreciates you so much. When you get a recommendation for a technical secondary school, tell him and he will definitely recommend you."

Wang Haoran said, “Let’s talk about it later.”

"Yougui, what products does your machinery factory have now?"

Zhao Yougui said: "We mainly produce iron plows, mechanized farm buildings, iron shovels, hoes, iron pots and so on."

“The benefits are not that good now.”

Wang Haoran smiled and said: "When I had nothing to do, I designed a small machine that can be used for manual seeding, weeding and fertilizing."

"Can I borrow your equipment and materials to make a sample?"

Zhao Yougui was stunned: "You are actually also inventing things?"

Wang Haoran said, “It’s not really an invention, is it?”

“It’s just a small item.”

"But it can greatly improve farmers' production efficiency. Isn't it time to plant the seeds soon? If this thing can open up the market, it will definitely help you improve your profits."

Zhao Yougui said, "Why don't you come back to the factory with me? Bring your invention drawings and let our factory director Dai Hongtao take a look. If he approves, maybe you can even get a bonus or something."

Wang Haoran shook his head: "It's in my mind. I can draw it on the spot."

Zhao Yougui shook his head and said, "I've been eating from the same pot with you for more than a year, and you're not willing to show off your real skills?"

"Come on, let me see how much of your abilities you are still hiding!"

At this time, there was no such thing as a patent.

If an individual invents something and registers it with an organization, the organization may give him some rewards.

Wang Haoran rode Zhao Yougui's bicycle to Mafang Machinery Factory.
