Husqvarna 125b Blower-Needs a Tune Up?

A customer brought me this Husqvarna 125b handheld blower with the request that it gets a tune up. Thats not a problem, I do tune ups all the time but this one has a secret. #smallenginerepair

Very similar to working on cars. Gotta spend more time removing stuff to get to the problem than it takes to fix the actual problem. Nice job

[@TheGreasyShopRag]

Ya thats often the way it goes but there are a lot of times when you can see the problem without taking anything apart. Like when someone puts a chain on backwards.

This video saved me a huge amount of time. I watched it to orient myself with this model blower before working on a family member's 125B that wouldn't start. I quickly found a fully plugged muffler screen, full of dried mud and live wasp larvae. The carb was still mounted tight at least so I didn't have to tear into it too far. Thanks!

[@TheGreasyShopRag]

Good job on that repair!

Mud Dobber’s Nest I’ve Ran Into That on a Few Generators I’ve Repaired Lately 😀 Nice Catch 👍🏼

[@TheGreasyShopRag]

Ya those bugs are a pain

[@groverw7507]

Ordered a refurbished 125b and this vid is very helpful to seeing how it's put together. Confused about removing the impeller to get to the carb screws though because it looks as if you gain access to them by removing the fuel tank?. Thanks for the lesson!

[@TheGreasyShopRag]

Theres a plastic wall blocking access to those screws.

[@steveriggenbach90]

Another reason to keep the screen on. You got me into a habit of shaking all carbs now. Take care.

[@TheGreasyShopRag]

Ya gotta shake em. Many of the older ones are loose!

[@hawkercaine]

excellent vid

[@TheGreasyShopRag]

Thanks. Its funny that your comment had to be translated to english from "excellent vid" to excellent video".

I have the same blower and it dies as soon as I take the choke off. I thought it was bad gas, so I put the Husqvarna premium gas in it, which is about $30 a gallon and it still runs rough. Could it be the spark plug?

[@TheGreasyShopRag]

I can almost certainly say no its not the plug. Its starving for fuel. Look in the tank and see if the fuel hose and filter are intact. If they are then you may need to look into the carb.

[@lotus956]

I just get a kit on Amazon with spark plug, filter, hoses and carb. Pretty easy to do. I do this every 2 years and it runs perfect.

[@JasonTHutchinson]

@@lotus956 I fixed it, turned out to be a bad fuel filter. I put in some bad gas and it was totally clogged. Works great now. I think the carb needs a little adjustment. I get a faint smell of unburned fuel now and then. I bought the tool to do it, just haven't gotten to it yet.

[@brianbeach5658]

Unfortunately, I’m still stuck. New fuel lines, new carb, exhaust screen and muffler are free and clear, and the two bolts beneath the carb are confirmed to be tight. Still the same result following the fuel line replacement and later, the carb rebuild, prior to replacement. The motor will start on full choke, only. It may be worth mentioning, that this is only after an egregious amount of pulls. After idling up, the motor dies. Any input from the throttle, or touch of the choke, will immediately kill the engine. Help!

[@TheGreasyShopRag]

The first two things that come to mind are lack of fuel and air leak. Maybe you have a bad crank seal? maybe those fuel lines are switched? Its hard to say for sure.

[@brianbeach5658]

@@TheGreasyShopRag I’m beginning to think it’s internal to the engine too. I know the fuel lines aren’t swapped. Because of your video, I knew to route them the correct way. It primes very well. I don’t know the history of this machine. There could be a very good reason it was stowed away to rot. Thank you for your consistent responses.

[@joedoakes8778]

Nice video, thank you. Which kit do you prefer? I need to tune up my 125B and the Husqvarna kit has a plug, air & fuel filters and that's it.

[@TheGreasyShopRag]

Sorry. I'm not familiar with any kits. We use individual parts as needed and don't sell kits in the showroom either. Thanks for watching!

[@joedoakes8778]

@@TheGreasyShopRag OK, and thank you.

[@JamitinThereRepair]

What do you set your driver clutch to when driving in the screws?

[@TheGreasyShopRag]

That SnapOn driver works well at #3 for most course thread screws into plastic with the 1/2 speed selector set on low speed.

[@powerup9895]

How do you dispose of old bad fuel ?

[@TheGreasyShopRag]

Thats a problem, isn't it? I put it in a drum and management hauls the drums away. I think a lot gets filtered and run in equipment that isn't so sensitive to fuel quality.

[@powerup9895]

@@TheGreasyShopRag do you guys charge customers to dispose of the old bad fuel ? I’d imagine it adds up quickly

[@TheGreasyShopRag]

@@powerup9895 We don't have a separate charge for fuel disposal but we do have one called "shop supplies". I guess it falls under there. Everyone gets charged shop supplies but not everyone has old fuel to deal with so I guess it works out.
