Experienced gardeners share their insights in answering this question :
This is classic fuel starvation, replace the fuel filter in the tank, check the fuel hoses from the tank to the carb for signs of leaking or slits and cracks, failing that you may need to adjust the fuel mixture, there is a special tool to adjust the mixture screws, part no. 530035560 ( try the web for sellers ) once you have the tool unscrew the H screw 1/4 turn to adjust the upper fuel supply.
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
When your trimmer starts and runs on choke, it could be because the check valve in the gas cap is clogged. Start the trimmer and gently unscrew the gas cap halfway off. Turn the choke off and assess. If the engine is still running, that means the gas cap may be the culprit.
Check to ensure that there is fresh, clean fuel in the fuel tank. Also check the fuel filter, because a clogged fuel filter will prevent the engine from obtaining adequate fuel supply.
It uses dual . 080-inch cutting lines.
Why would the engine only run while the choke is on or with repeated manual priming? An engine that requires the choking (partial or full) after initial engine warm up is an indication that the engine fuel air mixture system is out of adjustment.
If your trimmer engine idles, but stalls on throttle, check the following parts: the gasket, primer bulb, fuel filter, air filter, fuel vent, fuel line, and carburetor. The repair and symptom guide will help you better identify the part needed to be replaced and how.
The correct mixing ratio for your Husqvarna is detailed in your product`s owner`s manual. But as a general guide, a fuel-to-oil ratio of 50:1 is recommended for Husqvarna products up to and including 75cc. That comes out to 2.5 fluid ounces of oil per 1 gallon of gas.
Just Like Spark plug fouling, too much oil in the gasoline, inferior oil, a dirty air filter and/or continued operation at less than full throttle will plug the screen with carbon deposits. This prevents exhaust gases from flowing out, which leads to power loss or not running at all.

My Z5426 won’t start. When I pull out the choke and turn the key, gas starts leaking out of the exhaust system just before it gets to the muffler. Last time it did start, it ran really rough. So, I turn off the engine and then tried to restart and that’s when I noticed the fuel leak.
ANSWER : Maybe bad fuel, fuel line leaking, flooding of the carburetor, since it did start and ran rough I am assuming that the gas was left set and more then likely this gummed up the carburetor, you will have to clean/rebuild it. If you have a can of carburetor clean you may be able to spray that into there and clean it up, I would not choke it to start it as it sounds like it got/is flooded/ing. Good Luck Tim

Just bought a husqvarna 125 B blower at the end of last summer. It starts right up but when I give it the throttle, it bogs down and has no power. The fuel is fresh and clean and there is a new spark plug in it. I pulled the carb and made sure the ports were clear. Also checked the fuel line in the tank.
Is there a speed adjustment screw I should be looking at?
Any suggestions would be greatly appreciated.
ANSWER : Ajust the high speed carb screw or run on partial choke

Husqvarna Z6127 won’t start after running 30 minutes.
ANSWER : If the starter motor is spinning, the problem is probably the starter motor solenoid. It is basicly an electric piston mounted on the starter that engages the starter motor pinion gear to the flywheel.

Just bought a Huszvarna 405e chain saw, just put gas/oil in it. It started easily but after it settled into idle, I could give it about half-throttle and it would rev up, but any more throttle than that and it would die right away. Tried a bunch of times.
ANSWER : It is running too lean, it needs to be richened up on the carb screws, as there are special tools to do this i would take it back to where you purchased it , or back to a Husqvrna servicing dealer.
