Causes and ways to fix the lawn mower that is not explosive, difficult to explode

No explosion or explosion is one of the most common problems with lawn mowers (lawn generators). So the main cause leading to this situation is what? How to fix it?

Due to fuel

Failure of a jerky mower can be caused by exhausted fuel or dirty gasoline, impurities or dirt. The fix is ​​very simple, if the gas is out, you need to refuel, but if the gasoline is dirty, you should remove all modern gasoline and replace it with a new fuel that ensures more quality.

Due to the wind butterfly

If the wind butterfly is open, the lawn mower will not explode. So check and make sure the wind butterfly is closed before starting the lawn mower.

Due to spark plugs

Explosion-proof, explosion-proof lawn mowers may be caused by missing spark plugs, broken carburetor BXC or missing spark plugs, ICs. In this case, you can fix it by cleaning the dirt and dust, adjusting the spark gaps to the correct position. If you do all of this and still can't start it, chances are that the spark plug is damaged and the scale is replaced.

Because the ratio of gasoline to the lawn mower is inaccurate

 

Lawn mowers 2 are fueled by gasoline. The ratio of gasoline to the lawn mower must be accurate, neither too little nor too much. Because if too much oil is mixed, it will lead to soot in the spark plugs, causing the spark plug to fail quickly, the lawn mower will not explode and it creates a lot of black smoke when running. If too little oil is mixed, it will not lubricate the machine enough, making the parts quickly damaged by friction. The only remedy for this is to make sure the lawn mower's gasoline and oil have been properly mixed at the rate specified by the manufacturer.

Due to the fuel tank is sludge

With long-used lawn mowers, the fuel tank is easy to settle. You need to remove the fuel filter and check if it is able to draw gas, if it is blocked. If the filter is damaged, replace it with a new one.

Because the gas tank is loose or cracked

Loose or cracked gasoline oxide makes gasoline spilled out, fuel is not sucked up into the fuel tank (engine processing), leading to the state of the lawn mower jerking and exploding. You should replace the new gas tank for the lawn mower.

Due to the fuel tank (processing)

After a long period of operation (about 3-4 years), the rubber membranes of the carburetor may get in. As a result, these rubber films are hardened, unable to create vibrations to suck up gasoline, making the lawn mower difficult to explode or not to explode. The remedy in this case is to replace the vibrating membrane in the fuel tank.
