Check with a husq.dealer,they had some crummy carbs that may need replaced not rebuilt

Testimonial: "Jeff, how do you know this? The saw ran good for years. Why would carb be a problem now. What kind of carb do you suggest?"

SOURCE: Husqvarna chain saw starts and runs for 20 minutes then stops.

two things could be happening.......first is vapor lock......make sure you breather tube is clear and working........next is ....it could have a bad ignition coil on it.....after the coil gets hot the spark can become irratic or just not work any more.....

SOURCE: my husqvarna 350 chainsaw starts but wont stay running for more than a few seconds

Eric:

Find the gas/air adjustment screws on the carb (next to the the throttle cam where the throttle cable attaches. Turn the screws in all the way... GENTLY... Those are needle valves, and too much torque on them will damage the needle valve seats. turn both of them out one and a quarter to one and a half turns. Start the saw, and adjust one or the other screw in or out until the saw runs properly. If there is a plastic stop installed on the screws, remove it first, and replace it after the saw is running properly. You have to be patient while tuning the carb as it may take a while. If you adjust too much and the saw refuses to start at all, start over with the 1-1/4 to 1-1/2 turns out on the screws.

Why does it run only with the throttle in choke position?
Hi John:
Sounds like it's too lean.
Try backing out the high speed screw 1/2 turn at a time until you don't need the choke. Then tune the high speed with saw running at full throttle. Screw in (lean) until RPM starts to drop, then back out 1/3 to 1/2 turn. Then set low speed at idle so engine is smooth but chain does not turn.

My Rancher doesn't maintain high rpm. What's wrong?
Most 2-cycle chain saws have 3 carburetor adjustments; idle speed, low RPM fuel/air mix and high RPM fuel/air mix. The fuel/air mix needle valves will probably require a "special" driver tool to adjust them. Be careful with the adjustments, you can really mess things up by incorrectly adjusting them, then your saw goes from running poorly to not at all.

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...
Check air filter- clean or replace, Make sure you have fresh fuel, A new spark while you are giving it a service, Do you know how to tune the saw? Start with basic settings 1 turn on the low and 1 turn on the high And adjust from there, You might have turned the idle up too high. The choke should always be fully in when saw is running. Hope this is a good start

Poulan 45cc chainsaw will start running with starting with choke, but will not stay running.
Sounds like the low speed fuel adjustment is out of whack....you can reset it by turning it in all the way clockwise...then as a starting point, turn it out 1 and 1/2 times, start the engine and slowly adjust the screw until the engine starts to choke out..when this occurs, turn it back in until it starts to choke again...then you need to set it somewhere in between to find the "happy medium"....thew high speed screw is adjusted after you get the engine idling properly...if you haven't messed with this then I wouldn't worry about it..unless you have poor high speed operation, then you will need to set the high speed screw...the object here is to obtain the best low to high speed throttle...if , when you throttle up the saw, the engine bogs or goes to high speed slowly , here is where you adjust to get the best throttle response...use small increments until you achieve the desired response

Can't set carb. on Husqvarna chainsaw.
Most chainsaws and small engines are 1.5 turns out.

You need to set the mixtures for the carburetor. You will find a Low and High adjustment screw. At idle turn the screw in or clockwise until the rps starts to decrease. Then start turning it out till you hit max idle rpms. Turn screw back in a quarter to half turn and it should be idling smoothly. Be careful here and get someone to hold saw if necessary but hold in throttle to full speed and do the same with high adjustment screw. turn it in till rpm starts to drop then back it out until you get to max rpm and it won't go any higher then turn it back in a half a turn.

Husqvarna 51 chainsaw will barely run, magnito and carberator ok
Probably need to re-adjust the carburetor jets. They are very small screws in the base of the carburetor. They will be labeled with an "H" and an "L" . Set the low speed first by turning it in slowly until the rpm drops slightly then start turning it outward untill the engine idles smoothly. At that point you can also adjust idle speed. Then you need to be careful here but you need to hold the throttle wide open at the same time adjusting the high speed jet. Turn it in until the rpm drops then slowly turn it out. The rpm will keep increasing. Once you get to a point where it is max'ed out then screw the jet back in one half a turn. Changes in altitude like using your chainsaw in town versus going to the mountains for firewood can sometimes make it necessary to adjust the fuel/air ratio.
