If still under warranty have it serviced (authorized dealer not Joe's lawn mower). There should not be a fee (paid by Husqvarna). There have been carburetor problems. If you adjust it your warranty will likely be void; Joe's small engine service just as likely to void any warranty. Are you using a fresh 40:1 fuel oil mix. The will not start with choke set is normal. Start procedure in your OM says listen for sputter and disengage choke. Almost all new saws have similar start procedure. Start Procedure Cold:
Ignition on/off to on.
Set compression release – optional step even if saw is equipped with a compression release.
Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4).
Set compression release – optional step even if saw is equipped with a compression release.
Push (open) choke pull starter until it starts. (usually first pull).
Warm:
Ignition on/off to on.
Set compression release – optional step even if saw is equipped with a compression release.
Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed.
Push (open) choke, pull starter until it starts. (usually first pull).
If you have more questions or need additional help please reply below and I will get back to you. HTH & Good Luck. Lou Thank You for using FixYa.
Place the saw on full choke with the switch on. Pull the rope until it fires. Place the saw on half choke, and pull again, and it will start running. Half choke should release as soon as you hit the trigger.
I think the warm start procedure in the manual is causing it to flood. Try it like this, if you continue having problems reply below and we will try something else. PLEASE read #3 (Cold and Warm) a few times before attempting to start. Try it without 1/2 choke (your manual); completely open. Start Procedure Cold:
Ignition on/off to on.
Set compression release – optional step even if saw is equipped with a compression release.
Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4).
Set compression release – optional step even if saw is equipped with a compression release.
Push (open) choke pull starter until it starts. (usually first pull).
Warm:
Ignition on/off to on.
Set compression release – optional step even if saw is equipped with a compression release.
Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed or at 1/2 choke position.
Push (open) choke, pull starter until it starts. (usually first pull).
Start at 1.5 CCW form lightly seated then tune for performance like this: Carburetor Adjustment by Madsens.com http://www.madsens1.com/saw%20carb%20tune.htm CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly. Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run. There are 2 wav (sound - idle & full – may not be highlighted) files that I find most helpful, I think you will too.
I think your starting procedure may be the cause of flooding. Flooded is the #1 cause of hard starts in 2-cycle engines. Read carefully the recommended start in your manual. most miss the second note. It should be similar to this (read 3, read it again):
Warm start in the manual says 1/2 choke BS. Close choke, (sets fast idle) open choke, pull rope. Start Procedure Cold:
Ignition on/off to on
Set compression release – optional step even if saw is equipped with a compression release
Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4).
Set compression release – optional step even if saw is equipped with a compression release.
Push (open) choke pull starter until it starts (usually first pull).
Warm:
Ignition on/off to on
Set compression release – optional step even if saw is equipped with a compression release
Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed.
Push (open) choke, pull starter until it starts (usually first pull).
If you still have trouble reply as you did before. I will get back to you. HTH Lou
I am going to assume you are following the warm start procedure in your manual. Most start problems with 2-cycle engines are caused by flooding.
Before you shut if off roll it to the side and loosen the fuel cap (vent tank - leave it loose until restart) Better? Repair fuel vent. No better carburetor needs small adjustment. This explains it better than I can but you will need to experiment some. Carburetor Adjustment by Madsens.com http://www.madsens1.com/saw%20carb%20tune.htm CW is leaner; to lean will destroy the saw.

Just because this is the most likely cause: Start Procedure Cold:
Ignition on/off to on
Set compression release – optional step even if saw is equipped with a compression release
Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4)
Set compression release – optional step even if saw is equipped with a compression release
Push (open) choke pull starter until it starts. (usually first pull)
Warm:
Ignition on/off to on
Set compression release – optional step even if saw is equipped with a compression release
Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed.
Push (open) choke, pull starter until it starts. (usually first pull)
I hope you found this helpful. You can reply below if you need additional help. Lou
It must have spark, fuel and compression to run. Your task is to figure out which is missing.
Sometimes electrical components quit operating once beyond a certain temperature. Does it always start cold and become tempermental when warm?
IMO most hard start problems on a chainsaw with a good fuel delivery system are flooded. Start Procedure Cold:
Ignition on/off to on
Set compression release – optional step even if saw is equipped with a compression release
Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4)
Set compression release – optional step even if saw is equipped with a compression release
Push (open) choke pull starter until it starts. (usually first pull)
Warm:
Ignition on/off to on
Set compression release – optional step even if saw is equipped with a compression release
Pull (close) choke, set fast idle (done when choke closed on some saws) - Don’t pull with choke closed.
Push (open) choke, pull starter until it starts. (usually first pull)
The 3516 is a MTD McCulloch (Chinese). These saws are in a class by themselves. Good Luck Lou
I suspect she is flooded. Flooding is the most common cause of fails to start on a chainsaw. Remove the plug I bet it's wet. Start Procedure Cold:
Ignition on/off to on

Set compression release – optional step even if saw is equipped with a compression release

Warm:
Ignition on/off to on
Set compression release – optional step even if saw is equipped with a compression release
Pull (close) choke, set fast idle (done when choke closed on some saws) - Don’t pull with choke closed.
Push (open) choke, pull starter until it starts. (usually first pull)
Hope this helps Lou I've a 359 one time I forgot to pull then push the choke (sets fast idle). My shoulder gets sore just thinking about it.
ok starts how long?
and is this after pumping the primer? also choke postion make sure you change it after it starts right away and make sure look under air filter to see if choke is closing when operating choke.
