Husqvarna Power Cutter (concrete saw) carb removal and replacement

Hey everyone!
This is a step by step how-to on removing and replacing a carburetor (carb) on a Husqvarna power cutter.
People often refer to these as a “quick cut saw” or a “concrete saw”
I cover the required disassembly and swap out with a new aftermarket carb.
It’s working great and ready for the job site!
Cheers,
-Dave

Good job Dave, I am learning more and more about 2 stroke engines. It is so satisfying when you have a machine that is not working and you make it work! So i want to learn much more about it!

[@DavesSmallEngines]

I agree Robin! I totally have that same feeling. It’s a huge sense of pride and accomplishment!

[@joeyg-smallengine1116]

I mainly work on 4 stroke engines but its still nice to learn about 2 strokes. Hopefully this summer I can get my hands on some 2 strokes. Great video Dave! Joey from Ottawa

[@DavesSmallEngines]

Thank you Joey! Let me know if you have any questions, I'll try my best to help out. Cheers!

Thank you for a easy to understand video

[@donyboy73]

Great repair Dave!

[@DavesSmallEngines]

Thanks buddy!

I'm working on a 770 I got sick of it , after a good month of working on it after work in my spare time I've managed to rebuild it ,make it run only to discover that if you set it at idle it will die , and if you have fuel in the tank it will flood the engine pouring out of the intake, it needs a new carb mine too .
Yours is missing a filter, it has two.
Plus you should check the carb tuning as it has to spin at 9300 rpm at max .
Mines going to spin at 8800 rpm for safety reasons.
The engine itself can go way higher I guess,but the fact it's not spinning a chain but a cutting wheel can become dangerous if it goes higher than what Husqvarna originally tuned them for.
Because the cutting wheel can actually break in pieces causing injuries

Great video Dave. Have a great day 👍🏻

[@DavesSmallEngines]

Thanks, you too!

[@michaeldominy2084]

Now that started remarkably well for the first time.🤔🤔😊

[@DavesSmallEngines]

Awesome saw!

[@MundodasMana]

thanks brother.

[@wniner8194]

Great video! It looked like you had one screw left over sitting on the shop towel! LOL That’s my usual trick! Regards.

[@DavesSmallEngines]

Haha, I’ll go back and check it out. Maybe it’s weight reduction?

[@henrymurawskibigdogrepair]

Great job Dave

[@DavesSmallEngines]

Thanks Henry!

[@nashguy207]

Good job Dave. You are becoming a great 2 cycle mechanic!

[@DavesSmallEngines]

Thanks Nash! Glad to have you back.

[@michaeldominy2084]

Hi, A very clean and informative video😊. I don’t know if you can suggest my problem with the same cutter, it runs but on full power it won’t reach top speed, and after running for some time, and you stop it, it then won’t start again.🤔

[@ebfromwyoming4118]

great job dave

[@DavesSmallEngines]

Thanks EB!

[@Bungi81]

Hey Dave.
Good job 😉👍

[@DavesSmallEngines]

Thanks for the visit Stefan!

What were the symptoms of a faulty carb. I've just purchased a battered K760 and it starts fine, but when I press the choke in, the saw just goes into max revs and sounds like it's on full throttle

[@andrewdanilowicz3487]

I have a k770 just put a new carb on it and it seems to smoke quite a bit. Is there any adjustment on these carbs? Or is there something else I should check?

[@markmacdonald6452]

Good video Dave. Those saws have a pretty crappy way of securing the intake manifold. Only 1 bolt. I've seen them leak there and burn up the cylinder, poor design from Husqvarna. Too bad, because these saws mare very expensive.

[@rogermcdonald1607]

Another great video Dave.👍When you replaced the carb did you use an OEM carb or aftermarket. As you know i mostly flip mowers. If i have a carb that i cant get clean, i try to find another OEM carb that i can rebuild as i dont trust most of the Chinese carbs. I have better luck with OEM used than chinese. Your videos are very informative! 👏🇺🇸🇨🇦Roger

[@DavesSmallEngines]

Hey Roger! I used aftermarket... I have had good luck. If you're lucky, the carbs are exactly the same but are end runs from the factory without the stamping. Cheers!

[@stellarproductions8888]

Holy cow thats a big saw, what does that weigh Dave, 20-pounds? I think those machines are on their way to obesity. You did a wonderful job repairing that saw, love watching you have fun with these repairs. And as always, thanks for sharing buddy. :)

[@DavesSmallEngines]

Hey Stellar! It is a big saw. That 3120k was much bigger too! Thanks for watching!

[@donyboy73]

it's also a bear to pull!

[@stellarproductions8888]

@@donyboy73 Yeah, I'm guessing no compression release, probably 80cc saw, high compression, that be a monster to start by pull. They need to install electric start on those things, or do the spring wind up start.

[@michaelfarris2556]

Nice fix was it as fast as that to repair?

[@DavesSmallEngines]

Yep! Not much more to it. I had done the coil already but that doesn’t take long.

[@KensSmallEngineRepair]

Never seen such a clean cut off saw. Usually filled with concrete dust! Did you clean it first?

[@DavesSmallEngines]

Hey Ken! Just a quick wipe down with a towel. 30 seconds or so.

[@rickysmallman6428]

Hello mate. The choke has suddenly stopped working on my K760. Do you have any videos or tips?

[@DavesSmallEngines]

Hey Ricky - I don’t. Sorry!

[@donvoll2580]

Good video. Thanks

[@DavesSmallEngines]

Thanks Don!

[@davidpmartin5739]

could you list the carb adjustment

[@brianking1138]

I have never worked on one of those. The intake is really strange.

[@DavesSmallEngines]

Pretty unique eh?

[@darylpowell4388]

Where do you order the majority of your parts?

[@DavesSmallEngines]

Amazon, Aliexpress, ebay!

[@dujeamizic3588]

What about 261?

[@DavesSmallEngines]

Hey Duje! I am still waiting for the parts! Cheers!
