Unit is running lean. The lo is closest to the crankcase. Give the lo a half turn out.

SOURCE: Husqvarna model 125b Hand held blower (Gas) No

If you have tried a new spark plug and you still have no spark, then your Ignition Coil, (Module) has gone bad. They aren't cheap if you buy it new. Try to find a used one if you can for around $10.

Good Luck!

I have a Husqvarna 125 BVX Husqvarna 125BVX Leaf Blower Carburetor adjustment HELP

There is a special tool required as the screw heads are splined, base settings are 1 1/2 turns on both, it should run at this, the L screw will adjust fuel flow from idle to half throttle, the H screw will control the fuel to full rpm.
If the engine struggles to pick up, unscrew L screw a further 1/4 turn, or more until it picks up cleanly.
Now at full revs, gently screw the H screw in until engine sounds sweet, if it starts to die unscrew to achieve full revs.

What are the screw adjustments for the carburetor for 125B Grass Leaf Blower?

These should be set by a certified dealer using a tachometer. It is against Federal law to tamper with the adjustment screws. You can also damage or destroy the unit if they are not set properly.

Have you checked the Flame Arrester in the Muffler. They clog easy and engine can't push out exhaust.

Husqvarna 125b trigger stays on full

There is a manual lever on these that holds the trigger at different settings. Check and if it is full on, move it to the other extreme.

Trigger stuck on full

This machine has a metal throttle rod from the trigger to the carb, you need to look at the side of the carb where the rod connects to the carb, with your finger ( with the engine stopped ) work the carb throttle spindle manually to see if it is moving freely and it springs back to the small throttle idle screw easily, if it does unscrew the idle screw with a cross head screw driver until the machine idles ok, if not you need to take the l/h side cover off to investigate what has happened .

Why does my leaf blower bog down under acceleration

Just a shot.Look at the exhaust and see if the end of it screws out with a socket. If it does, clean the excess carbon thats on it and reinstall it.

Husky 125B blower, new right out of the box. starts, runs about 30 sec, bogs and quits. I'm guessing likely needs carb adjustment, but set screws are not regular slotted screws. Looks like it requires a...


Hello,
My name is Dane and I am going to assist you in solving your problem.

You will need to adjust the high speed setting on your Carburetor jet. Turning the screw out just 1/2 turn or so should do the trick. It is not so hard to adjust the Carburetor, however, yes you do need a special tool that is very hard to get your hands on, in order to adjust the jet screws. They don't make many engines with plain screw heads anymore. The newer Carburetors are factory set lean so they can pass emission standards. Since you just bought yours, a local husky dealer should adjust the mixture for free. I hope I've helped. If you found this reply useful, please leave me some THUMBS UP, if you feel I

Stihl leaf blower motor dies when i try to give it full throttle

If the low and high speed screw are adjustable give them a try. Start with one turn on the low and two turns on the high speed. If these screws are fixed then you will probably have to put a carburetor kit in the carb. I hope this has been of some help. Donnyb60
