We have already talked about the adjustment of the oil saw carburetor. Today, it is mainly about the other problems of the oil saw carburetor and how to select the brand of oil saw. I
Think everybody thinks that a good oil saw, but so many brands do not know how to choose, today small make up for everybody analysis.
1. Gasoline saw a new carburetor to fill the tank?
May be the oil saw when the oil pipe or the installation of dirty things flow into the carburetor, the needle valve stuck, leading to high oil level! You need to pull down the oil.
The machine has been cleaned! Don't assume that the new ones don't need to be washed, and there's a tiny little hair in the tubing that can cause the needle valve to fail.
2. What is the effect of negative pressure tube on the oil saw carburetor?
The working principle of oil saw carburetor is:
When the oil bubble is pressed by hand, the air is discharged from the outlet of a single valve of oil-resistant rubber, back to the tank, and then out of the gas tank, and the rubber cover begins.
Compound, negative pressure, rubber cover cavity suction air suction, quantitative chamber rubber piers to be sucked, compressed reed, oil valve stem lift valve, this.
When the gasoline begins to flow into the oil pipe, the pump oil chamber is filtered into the ration chamber, then the single valve shunt of the copper retaining ring and some of it enter the idle conch.
Nailing adjustment control adjustable speed hole, low speed hole, the appearance of atomized gasoline. The other part enters the main jet hole controlled by the high speed screw, which can appear more.
Multi-atomized gasoline; You can start the engine when you close the choke.
After the engine work, the carburetor pump oil chamber has a back hole on the side, straight through the crankcase, when the crankshaft turns around, because the piston moves up and down, living.
The gas in the plug flows back and forth into the stoma, and then pushes the diaphragm of the carburetor pump oil chamber to vibrate. Due to the effect of airflow, the flow rate of oil is accelerated and accelerated.
At the same time, the oil velocity is also started. Meanwhile, the quantitative chamber diaphragm vibration is also started, and the vibration quantification chamber diaphragm compression reed, the carburetor begins to absorb oil, shunt and spray oil.
