"I said Uncle Luo, you can't do it, it's been installed for a long time or it's rubbing" Yang Quan squatted on the ground and watched Luo Daodao slowly assemble the engine parts of the 70cc construction motorcycle brought back from the mountain city, and he was so anxious that he jumped up and hated to replace the assembly by himself.

"It's only been a few minutes, it's been half a day, your description is too exaggerated~" Luo Daodao sat on the stool and said non-stop.

"I'm in a hurry"

"Xiao Young is in a hurry, and he has to do things slowly, you said that if I put it wrong, wouldn't I have to dismantle it and reorganize it later?" Luo Daodao spread out his palm and gestured to Yang Quan.

"Don't stop, keep busy. Yang Quan saw that Luo Daodao was a prelude to preparing to talk nonsense, and immediately turned off the fire and covered his mouth and laid his hands on the side.

Speaking of which, Yang Quan has also lived for most of his life, and his temperament should be calm, but now his young body and mentality can't be controlled.

Luo Daodao is the most skilled in the factory, otherwise he would not often be assigned by the leader to work. Construction and Jialing in recent years are sold all over the country, as long as it is engaged in the automobile and motorcycle maintenance industry, everyone has more or less contacted, dismantling and reorganizing the engine is also a lot, so Luo Daoguo is effortless to install.

In about 20 minutes, a brand-new 70CC engine was placed in front of Yang Quanquan, like a newborn baby sleeping in the cradle, waiting for that moment to cry.

Luo Daodao found an old motorcycle and casually loaded and replaced the engine that had just been assembled. Turn the kickstart pad and press it hard, giving oil to your hands.

"Suddenly... Sudden ......"

"Get up, my skills are not bad," Luo Daodao unexpectedly started as soon as he didn't expect it, and said with a grin.

Yang Quan saw that Luo Daodao didn't care about it, and really wanted to go up and hammer him, and treat him like a treasure carefully.

In fact, the engine is not a princess who needs to be petted, and caring is chaotic, Yang Quan attaches too much importance to it.

"Don't speak, give me some oil, I'll listen to the voice. ”

"Uh......h Woo......"

"There is no knocking sound on the piston rings, there is no problem with the sealing part, there is no abnormal sound from the connecting rod, there is no black smoke from the exhaust, there is no problem with the carburetor, and the sound is stable and there is no abnormal noise. Wait and try to run again......"

Luo Daodao grabbed the accelerator and turned his ears more or less, carefully distinguishing the sound. An experienced maintenance personnel can hear from the sound whether there is a problem, which is the same as the sight, hearing and hearing of Chinese medicine. Although no final medical report has been issued, the condition is healthy.

The smile on Yang Quan's face had almost covered his eyes, and he saw that the exhaust pipe was exhausting normally, there was no black smoke and blue smoke, and the sound of the motorcycle starting was normal, so it was basically okay.

Wait for the next ride and then walk around the compound twice, find a slope to climb, and complete the simple test.

After the engine burst smoothly for ten minutes, Luo Daodao put up gear and rode for a test ride. By the way, the road in the compound was moving slowly in first gear, and Yang Quan was walking behind.

The first gear smoothly shifted to the second gear, and the speed became slightly faster. Yang Quan's steps are big, and the frequency can still keep up when he slows down.

From second gear to third gear, the throttle will be given more, otherwise the speed will not rise, and the motorcycle will be stuck a few times. Yang Quan let go of his steps and ran behind.

In the fourth gear, Yang Quan stood under the tree and stopped following, covering the sun with his hand and looking at Luo Daodao in a circle to accelerate.

Five minutes later, after all kinds of acceleration and climbing, after the test, Luo Daodao rode the car back to Yang Quan, turned over, got out of the car, raised his arms, wiped the sweat on his face, nodded heavily to Yang Quan, and said:

"No problem, normal use!"

Although he had already guessed the answer, he was still excited to himself after hearing the final judgment given by the doctor Luo Daodao. Yang Quan seemed to be unable to suppress the excitement in his heart, rubbed his hands around, and finally clenched his fists and hammered on the seat.

"It's done!" Yang Quan shouted!

Luo Daodao didn't know Yang Quan's plan, but he watched Yang Quan jump happily and laughed with him a few times. I thought that the young man's temperament was really jumping, and he could be happy for a long time with such a simple little thing, just like catching a fish in the reservoir, and said that the fish suddenly remembered that he seemed to ask Lao Zhang next door to catch a fish.

"Ouch, it's over. ”

"What's wrong with the engine, what's wrong?"

"I forgot to make an appointment with Lao Zhang, I have to go, or I'll be late. After speaking, Luo Daodao kicked the pedal, hurriedly ran out, and did not forget to turn around and shout to Yang Quan, "Just leave the car here, wait for me to come back at night to clean up, don't move, it's troublesome." ”

"Scared me, I thought there was a problem with the quality" Yang Quan looked at Luo Daodao and squatted in front of the engine after waving his hand and laughed.

The next step is to wait for the start-up capital to come back, and I have never looked forward to Zhou Aifu coming back soon. Yang Quan's hand touched the engine cylinder head printed with the letters YAHAMA and muttered.
