After seeing Zhao Guoyang reaching the test site, not only Mu Aijun, but also a few other people surrounded by the lawn mower were also surprised.

Hua Guosheng, Xu Dongfeng, and Chang Yuan, although they did not dare to yell, they all greeted Zhao Guoyang with anticipation.

The only one who didn't like Zhao Guoyang coming at the scene was Huang Xiaohua, who caused trouble.

This guy has always been arrogant, but now that he has caused such a misunderstanding, he will naturally lose face.

Originally, he thought that he could solve the problem himself. But after working hard all morning, Huang Xiaohua was completely confused. He already knew that this problem was not something he could solve.

Now Zhao Guoyang suddenly appeared in front of everyone in the posture of a savior, which further aggravated Huang Xiaohua's sense of loss.

Huang Xiaohua's face was naturally too blue, and others naturally had no time to take care of it. Seeing Zhao Guoyang arrived, Mu Aijun quickly waved his hand and asked everyone to give in and let him come over.

"Guoyang, please help me see why there is such a big problem with this batch of lawn mowers!" Mu Aijun pointed at a lawn mower and gestured.

"The fuel in the fuel tank is full, and the carburetor can also inject oil normally. The spark plug can also ignite normally. However, for some reason, it can only work for one hour, so it won't work. It will be shipped in the past two days. What should I do..."

Seeing that Director Mu was a little anxious, Zhao Guoyang hurriedly comforted: "Director Mu, don't be anxious first. The working principle of the lawn mower is not complicated. It can run normally, which means that the system of the entire machine is fine. As for the shortening of working hours, it may be related to the abnormal fuel system, which is not a difficult problem."

After hearing Zhao Guoyang's words so calm, Mu Aijun's heart was relieved.

He knew Zhao Guoyang and knew that this young man was always aimless. Since he said that it was not a problem, then there were at least 70% or 80% possible problems.

Wang Youchang, who was standing by, also said to him: "Yes, Director Mu. Guoyang had already told me on the way that the reason why our lawn mowers had such a problem is probably related to the changes in the mixing ratio inside the carburetor. Just adjust the air and fuel ratio inside the carburetor and it can be restored as usual."

Just as Wang Youchang and Mu Aijun tried hard to explain, Zhao Guoyang was already talking to Hua Guosheng.

Hua Guosheng nodded repeatedly when he heard this, and with Xu Dongfeng, Chang Yuan and the others quickly opened the shell of the lawn mower, revealing the structure inside.

After they finished this step, Zhao Guoyang stepped forward to check the cylinder sealing condition, and then checked whether there was any air leakage in the valve.

After confirming that there was no problem, Zhao Guoyang basically had a clear idea, it must be a problem with the carburetor.

Generally speaking, the carburetor can automatically proportional the corresponding mixed gas concentration in this state according to the engine's working state requirements.

However, due to the carburetors of this batch of new lawn mowers, Huang Xiaohua made modifications, which changed the space capacity inside, and this change did not correspond to the original parameters of the engine.

Now after the engine is working, the carburetor will still automatically match the original gasoline amount of space, so the concentration of the mixer will naturally decrease. It is natural to shorten the working time.

To solve this problem, you only need to change the height of the container float in the carburetor that controls the oil inlet volume, and you can do it.

Of course, the specific height changes will still take a series of calculations, which depends on how much Huang Xiaohua expanded the internal space of the carburetor.

Zhao Guoyang glanced at Huang Xiaohua who was standing silly next to him, and quietly took the drawings of the modified carburetor from him.

"Hey, you...what are you doing! This is the drawing I drew!" Huang Xiaohua then reacted and shouted loudly.

"Do you think I care about your many problems? I just want to see how outrageous you are!" Zhao Guoyang didn't reply.

Zhao Guoyang is not nonsense. It is true that there are too many problems on this drawing of Huang Xiaohua.

After this guy increased the internal space of the carburetor, he did not even think about increasing the cross-sectional area of ​​the oil outlet throat. This is a very low-level mistake in itself.

As for the concentration of the mixed gas, it goes without saying that this guy is even more impossible to consider it.

After seeing some data on Huang Xiaohua's drawings, Zhao Guoyang knew it.

He patted Hua Guosheng on the shoulder and signaled him and Xu Dongfeng to disassemble the carburetor to reveal the float room inside.

Based on the data obtained after his mental calculation, Zhao Guoyang adjusted the height of the float in the float chamber on the floating surface and then closed it.

After the few of them installed the carburetor again and restored the lawn mower shell, Zhao Guoyang said to Hua Guosheng: "Okay, Huagong. When returning to repair, just adjust the height of the float in each float chamber according to the height I just adjusted."

Hua Guosheng naturally believed Zhao Guoyang's words and nodded repeatedly.

Mu Aijun and Wang Youchang next to you looked at me and I looked at you, and they were all a little incredible.

It’s okay for Mu Aijun, after all, he is not a technical background. However, Wang Youchang, the deputy technical director, was also a little surprised by Zhao Guoyang’s series of actions just now and could not understand them at all.

"Guoyang, that's it... that's enough?" Mu Aijun saw that the old Wang beside him was thinking hard, and couldn't help but ask Zhao Guoyang.

"Well, don't worry, Director Mu. The problem with short working hours before was caused by abnormal fuel system. I just readjusted the mixing ratio inside the carburetor, and everything is definitely OK."

"Ah, that's it. Xiao Xu, Xiao Chang, you guys quickly try this lawn mower. We'll wait for the result here!"

Director Mu made a speech, and Xu Dongfeng and Chang Yuan naturally did not dare to neglect. The two of them started working in the bushes around the test site with lawn mowers.

Seeing the lawn mower "buzzing", Huang Xiaohua looked at Zhao Guoyang with a resentful look, and secretly prayed in his heart that the machine would turn off the engine in a while, causing this guy to fall apart.

Zhao Guoyang was very confident about his repair plan just now. He took out a pack of cigarettes from his pocket and dispersed the two factory directors and Hua Guosheng.

"The 'China' brought back by Director Mu, Director Wang, and Songjiang tastes authentic enough!"

Looking at his extremely leisurely appearance, Mu Aijun, Wang Youchang felt much more at ease.

The two of them took the cigarettes and lit them one after another. They began to ask about the trip to Songjiang in Zhao Guoyang in a row.
Chapter completed!
