24th November 2011, 07:32 AM #1 Chainsaw kicks when pull starting When I try to start my new chainsaw ….(Efco 38CC: I wanted to buy Husky, but my last small Husky was not very good and the dealer no longer sells them because he got sick of the smaller models) …. it sticks sometimes. I am pretty experienced at pull starting nice and smooth, and I can feel a good start. Just yank thoroughly but try to fiddle around with the best starting position of the piston before you start to pull real hard.
Let’s take a look at some of the most common issues that can come up when your chainsaw is hard to pull and the simple steps you can use to fix it. If the spring or pulley is damaged, the chainsaw cannot start and it will either feel too easy or too hard to pull. Often the chainsaw will start to fail and is hard to pull because it gets old and a part breaks.
chainsaw kickback when starting Related Question:
What causes a chainsaw to kick back when trying to start?
There are two circumstances that can cause kickback when using a chain saw. The first occurs when the moving chain at the tip or the nose of the guide bar strikes an object. The second situation is when the wood closes in, pinching the saw chain in the middle of the cut.
How do I stop my chainsaw kick back?
Stand to side of the cutting path of the chain saw. Position yourself so that you are not near the cutting attachment when the chain saw is running. Know where the bar tip is at all times. Install a safety tip that covers the nose of the guide bar on the saw to prevent contact with the kickback zone.
Why does my chainsaw stall when I give it gas?
Carburetor Adjustment An engine stalls when it’s getting too much or not enough fuel from the carburetor. Stihl chainsaw carburetors usually have three adjustment screws: one each for idle, low speed and high speed. If the saw stalls while it’s idling, adjusting the idle screw, which usually is marked LA, should help.
How often does chainsaw kickback happen?

What is the most common chainsaw injury?
The most common hazards associated with chainsaws are injuries caused by kickback, pushback, and pull-in. Kickback is the most common and poses the greatest hazard. Kickback occurs when the rotating chain is stopped suddenly by contact with a more solid area throwing the saw rapidly backward toward the operator.
Why does my chainsaw bog down when I hit the throttle?
If your chainsaw is bogging down when you give it throttle, this is often a sign of improper gas-to-oil ratio. If there is too much gasoline in relation to the amount of oil used, this is known as a “rich mixture” and can cause the chainsaw to run poorly.
Why does my Stihl chainsaw bog down when I give it gas?
The Job of the Carburetor 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.
Why does my chainsaw only runs on choke?
When your chainsaw only runs if the choke is on the problem, in most cases, is a result of fuel supply problems or a faulty carburetor. To fix the problem you should check and clean the fuel system and carburator.
What should you not do with a chainsaw?
Don’t Cut With Improper Blade Tension A overly loose or tight chain also wears out the drive sprocket and causes rapid chain and bar wear. To determine if your chain is properly tensioned, pull up on the chain. The drive links should still be in the bar groove. If the links come out of the bar, the chain is too loose.
How common are chainsaw accidents?
They can also quickly cause severe injury or death. According to the Centers for Disease Control and Prevention (CDC), approximately 36,000 people are injured by chainsaws annually. Medical costs for chainsaw injuries based on these facts amount to about 350 million dollars per year.
Where do most chainsaw injuries occur?

What’s the safest chainsaw?
Chainsaws are useful when doing work on your home, but they can feel dangerous to use. It’s not too bad if you know what you’re doing, but it’s so easy to make one wrong move—and then it’s game over.
Why does my chainsaw rev too high?
The throttle valve (butterfly) simply cuts off the supply of combustible air/fuel and the engine stops. If this adjustment is set too high, the high idle speed will cause the centrifugal clutch to engage and the chain will run. This is a dangerous condition and should never be allowed.
Why does my chainsaw spark?
The most common cause of sparks from a chainsaw is metal-on-metal grinding. Whether it’s cutting through wood that has a nail in it or a grinding of gears in the chainsaw housing, a metal-against-metal grinding is the most likely cause.
How do you adjust a Stihl carburetor?
Turn the H screw clockwise with a carburetor adjustment tool until the head is spinning as fast as it will go, then back off the screw carefully until the RPMs start to decrease. Turn the screw slowly clockwise again until the engine once again just starts to pick up speed.
