How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
There could be various causes: incorrect fuel mixture, carburation not calibrated properly, or a wet spark plug. In spite of their power and robustness, chainsaws are actually rather delicate machines that require careful and precise maintenance at every stage of their life cycle.
To fix a flooded engine, you basically want to get the air to fuel ratio back to its usual balance. You can first try to simply let the excess fuel evaporate. Open your hood and wait a couple minutes before you try to start your car again. And when you do start it back up, make sure you aren`t pushing on the gas pedal.
You can unflood your chainsaw in a matter of minutes by: Remove the spark plug and expel the fuel mix by pulling the starter cord repeatedly, refitting the plug, and starting the engine with several pulls on the starter cord with the choke OFF.
Typically, this is the fourth position on the chainsaw`s master control lever. By opening the choke, a richer mix of fuel will be supplied to the engine during starting. Some chainsaw models use a horizontal squiggle between two clear vertical lines to denote the choke position.
Many people wonder if a flooded chainsaw will fix itself? The answer is yes, but not always. By letting the chainsaw sit for about 20 minutes it will allow some of the fuel inside the engine to evaporate.
The first is the easiest and most common method. Let your chainsaw sit for 15-20 minutes to allow the fuel to evaporate from the engine and then repeat the starting instructions.
Pulling the choke lever provides proper fuel-starting mixture when the engine is cold. When attempting to start a cold engine, pull the choke lever outward to close. Slowly return the choke to the open position as the engine warms. Leave the choke in the OFF/OPEN position when starting or restarting a warm engine.
The easiest way to tell if your engine is flooded with gas is to remove the spark plug. If it`s wet, it`s flooded and you`ll need to let the cylinder dry out before trying to restart. Compressed air can help speed up the process.
In worst cases, the excess fuel can foul spark plugs, sometimes necessitating their cleaning or replacement before the engine will start.
What if the engine is flooded with water? If your engine is flooded with water rather than fuel, that`s a different problem. It could cause a lot of damage depending on how much water got in. To avoid flooding your engine with water, it`s best to drive carefully through fords and floods.
Stihl carburetors have three adjustment screws. One controls the fuel mixture when the engine is idling, one controls it when the engine is operating at low speed and one is for high-speed fuel control. When the saw bogs down during cutting, it`s usually the high-speed screw you need to adjust.
Actually, all STIHL AP system tools with the rain cloud symbol in the catalogue can be used in the rain, which is particularly useful with our British weather!
A petrol powered chainsaw has several moving parts. To keep these parts moving, a certain amount of compression is needed. Compression is generated by the engine via the crankcase and the combustion chamber.
The two most common reasons a chainsaw won`t idle are a blocked air filter and an idle screw out of adjustment. Other possible causes include: Dirty Air Filter. Idle Screw out of Adjustment.
Dirty Carburetor (air+fuel)
If fuel sits in the system for too long, the carburetor (and the engine and fuel lines) can become sticky and clog. Remove the air filter and spray the carburetor with carb cleaner—an aerosolized acetone spray made to remove the gunk.
Vapor lock is caused by heat. Excessive heat from the engine, exhaust system, and/or outside temperature can cause the fuel to vaporize in the lines. Some winter fuel blends and high altitude can lower the boiling point of the fuel. This can also contribute to vapor lock.
