Mine arent hard to start as long as I dont leave fuel too long and I follow the recommended procedure. I always thought my Stihl blower, trimmers, and saws started pretty good until I started using and collecting other brands. My Stihl doesn’t start any harder than my Husky or Jred saws.
If the operator has repeatedly been trying to start the chainsaw through the recoil starter system, they may have accidentally flooded the engine with fuel. If you believe fuel has flooded the chainsaw engine, pull the starter cord several times while holding the throttle, dry and replace the spark plug, and then try starting the chainsaw again. Gasoline will start to deteriorate if left unused and sitting, so if the chainsaw hasn’t been started in a while, be sure to check that old fuel is not collecting inside the chainsaw.
To clear excess fuel from the carburetor, place the choke lever in the Off position, hold the throttle trigger fully open and pull the starter rope 5 or 6 times. Try to start the chainsaw after priming the carburetor. Activate the choke by moving the lever to the full choke position and pull the starter rope 3 or 4 times to start the engine.
stihl chainsaw is hard to start Related Question:
Why is it so hard to pull start my chainsaw?
If your chainsaw is hard to pull, here are some common causes: The pully system is snagged or stuck. The starter assembly is stuck or sticky. The housing may be damaged.
How do I make my chainsaw easier to start?
Try to start the chainsaw after priming the carburetor. 5. Activate the choke by moving the lever to the full choke position and pull the starter rope 3 or 4 times to start the engine. If that doesn’t work, move the choke lever to half choke and pull the starter rope, 6 times maximum, to start the engine.
Why will my new Stihl chainsaw not start?
If the engine doesn’t start on the first three or four pulls, the fuel and air mixture becomes fuel rich, and if you continue to pull the starter while the choke is closed, there is too much fuel to ignite and the engine floods. You can simply wait for the fuel to drain, but there is a faster way to clear the engine.
What causes a chainsaw to vapor lock?
Vapor lock occurs when the fuel (usually gasoline) within the fuel delivery system overheats and vaporizes too rapidly. The resulting excess gas bubbles accumulate to the point of actually blocking normal fuel delivery.
What causes too much compression in a Stihl chainsaw?
Many problems with compression are related to fuel. Old or bad fuel can cause lots of headaches with yard equipment. Try draining any of the gasoline mixture left in the gas tank and add fresh fuel. If this does not solve the problem, it may be related to excessive fuel caused by problems in the gas lines and filters.
How do you start a Stihl chainsaw?
Pull the starter cord slowly with your right hand until you feel resistance. The cord will engage with the flywheel to spin the engine and start it. Pull the cord strongly and briskly while pushing down on the front handle to hold it onto the ground.
Can you push start a chainsaw?
The biggest advantage of an electric chainsaw is that you don’t have to pull a cord and it needs minimum effort to get it started. You can start it by just pushing a couple of buttons and there is no throttle to open.
How long to wait if chainsaw is flooded?
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.
How long to wait if engine is flooded?
Perhaps the best remedy for a flooded engine is time. Simply open the hood of your car and let excessive fuel evaporate for as long as you can. After about 20 minutes try starting your car again without hitting the gas pedal.
How do I know if my chainsaw spark plug is bad?
If it’s not producing any sparks at all, your chainsaw needs a new plug. If there are only a few sparks coming out of one side of the electrodes but none on the other side, it’s not bad enough for you to worry about, but it will affect your performance.
Will a chainsaw run with low compression?
Most chainsaws will operate well with compression readings that range from 100 to 160 psi. After checking the function of the starter assembly, the operator can move on to determining if compression is dropping or increasing.
How much compression should a Stihl chainsaw have?
According to Stihl USA, the minimum compression reading for their chainsaws should be around 110 psi. Some individual engines may run a bit higher or lower and the temperature of the tool can affect readings. A cool chainsaw runs low, while a hot engine that’s been running for awhile will usually be higher.
What would cause too much compression?
When a cylinder has high compression, it means there is liquid oil or a high carbon deposit in the combustion chamber, which displaces air. As the combustion chamber is essentially smaller, the air gets compressed more and the pressure rises.
