Chain saw starts but dies when I press the throttle. It seems like its being flooded.

There are several conditions and situations that this can occur, but let's try the most common. This is also for any STIHL saw that was manufactured before 2014, after that, the M-Tronic saws have a different starting method.
Normally this happens when the engine fired and it was not audible, and the rope has continued to be pulled with the choke on.
This method is approved, but EXTREME caution should be used, and the CHAIN BRAKE must be used.
CAUTION: Do NOT use the drop start method, this is not an approved starting method under any circumstance!
1) Place the saw on the ground that is clear of debris.
2) Set the Chain Brake
b) place the toe of your right shoe thru the rear handle,
c) support the saw top handle with your left hand,
d) pull the recoil with your right hand.
3) Make sure the choke is NOT applied, place the master control lever in the start position (one notch above the choke position)
NOTE: at this point, it helps if a second person can hold the throttle at the full or wide open position.
4) Make 6 rapid pulls (a few more may be required), you should hear the saw start to sputter, keep the throttle open until enough rpm is obtained that YOU the Operator can gain control of the throttle (the other person stands aside now in a safe position) and remove the chain brake. Keep the throttle open until the saw starts to run properly.
*NOTE 2: The chain brake is designed to not only stop the chain in case of 'kick back', but also is to be used in starting the saw until you have time to gain full operational control of the saw. However, extended rpms above clutch engagement can damage the brake band, overheat the drum bearing, damage the clutch shoes and clutch drum.

Carburetor needs to be overhauled and replace all fuel lines and fuel filter.

air filter dirty.Spark plug bad,or carb needs tuning.

Sure sounds like your fuel filter needs to be changed. If you can't blow through the filter with your breath then it is bad.

Genral starting procedure on a chain saw is as follows, put fresh fuel into the fuel tank, top up the chain oil tank,switch the ignition on, if the saw has a half throttle position on the trigger lock this, if the saw has a primer depress this as many times as it takes to 3/4 fill the bulb, pull the choke fully out, if it has a deco valve push this in, now place the saw on the ground with the chain brake on and crank the engine ( always have the saw body between you and the cutter bar,NO left hand starting, NO drop starting ) the engine will only fire once on full choke, do not continue to crank engine after the first fire or you will flood the engine, push the choke back in, crank the engine until it fires up and runs,release the chain brake and blip the throttle to release the half throttle device.

You Are Going To Have Too Rebuild The Carb.

It sounds like it is flooding when you use the throttle, both are connected. Turn the idle back all the way until it dies, then try turning it a 1/4 turn the other direction.

Oil fuel mix is important. Did you mix them at the right ratio?

You should also let the chain saw warm up a little before use, and the choke should be off.

If that doesn't do it, look in the O&M for making slight adjustments to the carb. If that doesn't do it, and the saw is new, take it back. But you really need to try the above first.

Is thereadjustment somewhere on the saw
I think there is 2 .

If it idles it is not flooding out as it it most vulnerable to flooding at idle if the stalling is happening as you try to throttle it up it is likely starved for fuel. Start by changing the in tank fuel filter, and the spark plug. good chance that will solve your problem. If it does not Turn the high idle screw out in 1/8 turn increments try running the saw after each adjustment. Keep track of the amount that you turn the screw. you might have to put it back to its original position. Some times adjustment screws will vi berate out of adjustment and other times crud will cause fuel restriction opening the screw allows for a larger port for any restrictions to pass through. After you use the saw for a short time turn screw back in if it starts to stall at idle or you notice increased smoke.
