Question: Husqvarna 125b Leaf Blower

1911496

My Husqvarna 125B began running bad and wouldnt start. I watched a few YouTube videos. As a result I decided to purchase a new caburetor and replace fuel lines. When I opened the unit, the old fuel lines were a mess. They were yellow one from the fuel tank to the bottom of the carburetor was broken. It appears the 10 years of ethanol gasoline had taken its toll. When the parts arrived, I took my time and reinstalled the new parts. When I pumped the primer bulb, it filled with gas. Now the fun part. I pulled and pulled and the unit did not fire up. I took the muffler off shot two sprays of starting solution and it fired up and beautifully. I thought that I fad attained victory. A day or so later I needed it for a small job. I had the same experience. I pulled and pulled and it wouldnt start. I sprayed the starting fluid and it started right up. So it appears that the only/ way to start this thing is with starting fluid... any ideas...
Are you using the choke correctly?
Question: Starting 125b Husqvarna Blower

Sapoe

Replaced spark plug, fuel line and carburetor, still won't start
Question: Husqvarna Blower 125B

1641189

My blowers not working right, it ran for one day on half choke and now wont stay running. Replaced the fuel lines, checked and cleaned the spark plug. Put in pre-mixed fuel. It was starting and wouldnt run long (acts like it ran out of gas). Now it wont start at all. Someone told me I need a carburetor kit? Can someone help me?
Question: 545132501

1305479

Does this boot come w/ a plastic insert
WJA
Hello 1305479,

By inspecting the 545132501 Carburetor Boot. There is a round plastic insert about half way in side of it. I hope this is what you are asking about.

-WJA
Question: Carb Jets

Durell

My blower will not stay running. It only runs at all because I push fuel into the carb via the plastic fuel bulb. But you would think there would be the possibility of disassembling the carb to clean jets, etc. I am sure my problem is dried fuel residue inside the carb. Any suggestions besides buying a new carb?
Put the carb in an ultrasonic cleaner and see if that clears it up.
To clean the carburetor jets: Add 2 oz. of Sea Foam Motor Treatment to each gallon of gas oil mix. Sea Foam Motor Treatment will slowly re-liquefy old fuel and petroleum. Run it until it runs on it's own.
Durell, Any luck cleaning that carb and getting it to run on its own yet?
Question: Husky 125B

whpete44

After running perfectly for several years, I found the prime bulb to not build pressure like it did in 3 to 5 pumps. Used to fire in 3 pulls, now won't hit a lick and smell gas while pulling rope. Has adequate spark and the plug is brown and dry, not getting gas. Checked gas lines and they are not leaking. Popped off the weighted pickup tube and cleaned, reinstalled. Same. What should I check next ?? Could the carbs diaphragm be blown causing this... Thank you for the help...Wendell

If the diaphragm were "blown", then there should be many cracks, and the diaphragm should be stiff and brittle...
If its a certain age (?), I'd replace it...
Today, I think I found the problem...the Purge Bulb (mistakenly referred to by me as the Prime Bulb) has a defective flapper inside it. I need to order a new bulb assembly, and maybe the problem will be solve. Thanks for your input earthworm.
Eureka!!! Same model, same problem, degrading performance, purge bulb would not pop back out eventually. Checked all the simple stuff, spark plug, filters, etc. After talking to shop guy, removed carb, removed the two plates on the carb, found deposits (the problem, and very hard to see) on the "small screen" in the carb. Brushed off/sprayed deposits off with carb cleaner and the rest of carb. Threw it back together and it runs great. I did it without replacing a thing, take it easy on the gaskets and diaphragm, very delicate. Shop guy said it's caused by ethanol fuels. The deposits form downstream of the fuel filter (my filter was completely clean!) Find a source of, and use only non-ethanol fuels in your small equipment. He said the the majority of his repairs now are ethanol related caused by corrosion from the moisture the is held in ethanol or the breakdown of components by the ethanol itself. Cheap parts not designed/manufactured to standup to ethanol yet.
