Why lawn mower hard to start when cold? The time of year is here and it’s time to get the lawn mower out of the garage and get to work. But have you ever noticed that it is more difficult to start a lawn mower in the cold than in the warmer months? Read this article until end to know more about it. In this blog, we also have an article about best high end lawn mowers that you might want to read about it.
Why Lawn Mower Hard To Start When Cold
Colder work settings might induce various modifications that make starting the lawn mower more difficult. The following are some of the problems induced by cold weather:
Reduced Flow of Oil
Cold weather increases the viscosity of oil, hence restricting its flow. To prevent this problem, choose an oil type that is suitable to cooler settings. Additionally, you may resolve this issue by raising the oil level in the mower’s oil reservoir.
Valve Issues
Metals expand and shrink in response to temperature variations. Metal shrinks in cold temperatures, which might result in smaller valve channels. If this is the case, you should seek the assistance of a qualified technician for valve replacement or repair.
Other reasons:
Inadequate or Substandard Gas:
The inadequate portion is self-evident. If your mower won’t start, the first thing you’d do is open the fuel tank and check to see if the gas level is too low. If it is, refill it and retry.
The problem of contaminated gas is a little more complicated. However, there is one basic tip to remember: do not let gas remain in the tank for an extended period of time. Gas left in the mower’s tank may soon deteriorate due to evaporation and oxidation. The oxidation impact is magnified considerably more with ethanol-blended gas (i.e., E10), which you are almost certainly using. Additionally, old gas damages the carburetor and fuel lines, resulting in a variety of additional issues that might finally result in your mower not starting.
Allow no longer than 30 days for gas to linger in the mower. If the tank has been sitting for so long, empty it and replace it with new gas before beginning. A fuel stabilizer is also an option if your lawnmower is not used for a long length of time, such as during the winter.
Fuel Line Blockages:
Fuel lines may get blocked by debris or by the thick varnish-like material formed when sitting gas oxidizes. When fuel lines are obstructed, fuel flow to the carburetor is interrupted, and the proper fuel-air mixture is not delivered to the combustion chamber. This results in incomplete combustion, which prevents the mower from starting. If your mower will not start or will not start at all, inspect and clear the fuel lines.
Air Filter Obstruction:
Debris accumulated in the air filter over time might clog it. Incomplete combustion occurs when insufficient oxygen enters the combustion chamber due to a blocked air filter.
If your chilly mower is having difficulty starting, examine the air filter. Clean it with a brush, soap, and water if it is filthy. If this does not work if the drain is unclean and blocked, replace it.
How to Start a Cold Mower
You do not need to be an expert to start a chilly mower. If the issue is not severe, you should be able to start your chilly mower by following the steps outlined below.
1st step:
Park your mower on an open, level area, and apply the parking brake. Using a wrench, remove the spark plug. Utilize a file or sandpaper to clean the spark plug electrode region. Then reinsert it and reconnect the spark plug lead. Ascertain if there is sufficient gas in the tank.
2nd step:
Remove and examine the air filter. Remove any debris from it with a screwdriver or by washing it. Then replace it.
3rd step:
Three times push the priming button, allowing it to retract before proceeding with the following press.
