Well, this time I will repair the generator that starts the engine but the idling is not stable. I overhauled the carburetor, but the symptomatology did not improve ... It costs about 20.000 yen to replace the carburetor, so I will overhaul the engine for the time being.

The inverter unit produces a sine wave of AC100V, which can be used to power precision machinery such as personal computers by creating electricity with a beautiful waveform.

The frame is damaged, so replace it.
1:22
To remove the rotor, use a special tool to prevent damage. There are times when you just apply tension and retreat.
1:40
In this way, it can be removed stably by giving an impact with some tension applied.
1:55
The rotational movement of the magnet rotor generates electric power in the stator coil.
2:05
The displacement of this engine is 171cc.
2:34
Each part is inspected and cleaned.
3:04
The oil seal on the crankshaft is press-fitted straight to the proper depth.
3:11
Piston rings have orientation and order, top rings use surface treated rings.
3:34
Incorrect installation of compression top dead center may cause damage or malfunction.
3:41
If the valve stem seal is bad, white smoke and poor fuel adjustment due to oil inhalation will occur.
3:45
The size of the contact surface is different between the IN valve and the EX valve. The IN side is made large to increase the suction efficiency, and the EX side is made smaller to increase the flow velocity.
4:03
The crankshaft converts the vertical movement of the piston into rotational movement, turning the camshaft, the lifter pushes up the push rod, moves the loker arm, and opens and closes the valve.
4:10
Oil is scraped up to the cylinder wall surface for lubrication.
4:20
A 4-cycle engine with a valve mechanism on the cylinder head is called an OHV.
4:27
The decompression operates only at the time of starting so that the engine can be started manually. When the engine starts, it stops working due to centrifugal force.
5:16
A proper clearance is required between the stator coil and the rotor, center them.
5:54
An appropriate gap is required between the ignition coil and the magnet on the rotor side, which may cause ignition failure of the spark plug.
6:22
Lecture fires use diodes to convert AC power to DC power. The stator coil has separate high-voltage (100V) and low-voltage (36V) circuits.
The cause of this malfunction may be an engine malfunction, or a throttle motor malfunction due to a damaged lecture fire. The parts cost was about 11.000 yen, so it was cheaper than replacing the carburetor.
