1. Check the candles
Check the spark plugs and if they are wet with gasoline, remove the moisture from the spark plugs. If the lawnmower engine does not work properly, it causes the spark plugs to heat up and negatively affect the performance of the spark plugs. If the spark plugs are dirty, you should clean the deposits from the electrode with special sandpaper. Also, check the distance between the candles with a filler, if this distance is more than 0.5 mm, you should shorten it. It should be noted that you should check the candles once every hundred hours.
2. Check the air filter
If your work environment is hot and dry and contains dust; The possibility of the air filter being blocked is very high. If the air filter is blocked, remove it and shake it by hitting the soil, and if the air filter is washable, wash and clean it. It should be noted that the air filter should be completely dry before installation.
3. Carburetor review
Carburetor is one of the most important parts of the lawnmower. In most of the observed cases, the lawnmower does not turn on due to the blockage of the carburetor due to gasoline dirt. Poor fuel quality and its dirt may cause carburetor blockage. If you have been using the lawnmower for about 2 years, most likely the main problem is with the carburetor. Periodic adjustment of the carburetor increases its life and saves money. It is better to replace the lawnmower carburetor every few years.
4. Dirty Fuel Fuel Examination
Dirt in the fuel filter rarely happens and because of the low quality of the fuel used, this filter gets clogged. Also, the impurities in the oil can also lead to clogging of the lawnmower's fuel filter.
