My e series 142 spins the chain and idles insanely fast when I have the choke pulled out. Then when I give it throttle it calms down and then I can barely keep it idling. with throttle all the way pulled it dies, with no throttle it dies. When I start it with choke it runs fast. I tried throttle adjustment. any ideas?

SOURCE: 39cc McCulloch chain saw

The issue sounds just like a carburetor problem. I had a saw that did the same exact thing, and found that I hadn't been adjusting the carburetor properly for years. I managed to find the instructions on-line, and then it ran like a dream, just every time I store it, I have to go back through the motions again.

Let me know if you need adjustment guidance and I will see if I can dig up anything.

SOURCE: saw stops when i give it gas.

• plugged fuel filter
• cracked/loose fuel line allowing air (instead of fuel) into the carburetor.
• poorly fitting fuel cap
• plugged or disconnected/broken pumper line

on your machine may be on the side of it that led into the carb should have H for high L low L is for the idle H is for all out ball to the wall you will need a small long screw flat head . put in the H ,turn out for more gas in for less good luck

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:

1. Ignition on/off to on.
2. Set compression release – optional step even if saw is equipped with a compression release.
3. 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).
4. Set compression release – optional step even if saw is equipped with a compression release.
5. Push (open) choke pull starter until it starts. (usually first pull).
