Hidden Carburetor Leak On Husqvarna Chainsaw Carburetor! Must see video!

[@fillslawncare]

This trick will come in handy on carbs that you can't order anymore 👍🏼

[@matthewsmith6330]

Especially older STIHL brushcutters like a old fs80 have a plastic inlet tube thats always split

[@robertforster9736]

Great tip donyboy. You always seem to find these head scratcher problems. I really like the way you go about things. Clean everything before taking things apart. I stress this in my shop as well. Look forward to your videos 👍

[@mikespain8655]

Difficult to locate that leak. I use a Mity Vac vacuum/pressure tester.

[@deanharbold858]

I'm not sure if u caN help but brand new fuel filter, lines,primer bulb,and crab... Rand for a few cuts and now it won't pull fuel into the carb so confused...... husqvarna 240e any help is great

[@easttnliving]

Great but what if the carb is dumping too much fuel into the cylinder causing flooding ? (Husky 455 Rancher Autotune)

[@swordfish1120]

Is one of symptoms of an air leak that a chainsaw will start and idle, but will die as soon as the trigger is pulled (compression is 160 psi and carb kit installed)? I have this problem on my Stihl 026.

[@nashguy207]

Thanks for the tip I would never of thought of looking there for a leak!

[@rudygeorgiamulesandcountry1594]

I JB'd rusted out axel splines on a Honda Fourtrax 250 to rusted out splines hubs. They held for 5 years, could do wheelies NP ; until someone stole it. To remove a hub to make a repair I had to aggressively heat it with an acetylene torch and hammer on it. Good luck to whoever's has it now.

[@donyboy73]

wow that's amazing!

[@MrBlackCharizard]

I used the steelstik on my generator gas tank and is holding up pretty well 2 years later

[@donyboy73]

good to know!

[@999thenewman]

Nice video. You can ghetto-fix it with some metal expoxy. That will get you by for a while. :)

[@cowbdave99]

Before you go patting him on 5he back. My opinion he went and replaced his oem carb for one of these 20.00 rip off of the Asian kind. Thinking that would be easier than doing a rebuild job. Only to find out . There junk. No stock Husqvarna chainsaw carb we have gaps like yours. One from China would. Am I right?

[@georgepouliot5383]

No cause husqvarna used Zama carbs in the 235/240 that were Total junk

[@lukepodolski8818]

Excellent demonstration video. That helps alot. Thank you so much.

[@upsidedowndog1256]

Great tip! I have the same saw. I would recommend Permatex sleeve retainer before the epoxy. It is thinner and will wick into smaller openings. Nice job.

[@johnbutler5650]

What is the Walbro part number for that husqvarna 445 carb? And, if it’s not too much to ask; what would the part number on that rebuild kit be? Love your videos bud!

[@donyboy73]

not sure, go to partstree.com

[@alanzanotti]

Show...Very good video...

[@Rickster2791]

I hate working on 2 stroke carbs. I can never get it right but I keep plugging away.

[@Dieselhorses]

Excellent video! This has got to be my issue as everything is new- both fuel related and electrical, will check pressure. Saw bogging no matter how I adjust.

[@robprice6573]

Great tip Don! I usually buy the five minute JB weld, will start burning the long set one now, based on your advice. I fixed a gas tank on an old BMW I had, and it lasted six years, then sold the car. Tanks was expensive! Thanks Don!

[@josephrich6014]

Nice to see other folks use JB Weld too. I have for years and yes the longer set stuff does seem stronger. Thanks for the vid.

[@michellatour150]

Buy a handful of 10ml plastic syringes (1mm tip opening/no needle) from the drug store, ideal for precisely applying JB Weld, RTV, Motoseal etc. without any mess.

[@crazycanadian7741]

Hey Don, can't find walbro tester 57-11-1 on eBay, always getting the Chinese version, can I get straight from the company,?

[@SW-lu9cu]

Thanks donyboy ! You always produce great useful content. Appreciate your videos.

[@donyboy73]

Glad you like them!

[@biking2cruze]

I didn't know about carb pressure testing! I fix small engines for decades and wondered why the carburetor leaked after a full rebuild! Now armed with new info, I can finally fix that carb leak instead of throwing it out to replacement!

[@billhopkins1553]

I'm not sure you will do this, but here goes-Can you show or tell me how to replace fuel lines on Jonsered model CS2245- thanksin advance,Bill

[@Dennis_J._Aitken]

That blade could use a sharpening! Great video! I have a really nice weed whacker with the same problem. Since I haven't started it yet I am glad I seen this!

[@douglasengle2704]

I got suspicious my Walbro 45A carb might be leaking after watching this video because when working on it I'd rotated the fuel inlet thinking it was meant to rotate. When pressure checking in water just the slightest pump pressure caused lots of bubbles to come out of the carb's venturi area. There appeared to be no restriction at all. I opened up metering side of the carb and found the needle lever was stuck all the way down! I didn't think the diaphragm could make that kind of long distance movement! I worked on the needle to un stick and pressed to the lever to stick it down a few times. When trying to get the FS66 to run at speed I'd tried in desperation to raze the needle lever to get more fuel. Not that much as it turned out just the width of the lever's metal thickness above the carb. body frame. I've now bent it to be flush with the carb body, which appears to be the stock setting. I wouldn't have checked the carb with pressure under water without this video! The trimmer refused to restart after one tank of fuel after replacing the crankshaft shaft seals. Shihl had stopped suppling the seals for an FS66 so I got generic double lip seals of the same dimensions. I had thought maybe there was something very special about the. Shihl seals because going one tank of fuel before seals with seals not up to the task was probably expected behavior. When pressure checking the engine the seals past the soap bubble test with 20 psi so they appeared good. I found a leak around the fuel pump pulse channel between the cylinder and the carburetor block when pressure testing the engine with soap bubbles. I order a NOS gasket from eBay because Shihl had stopped suppling this gasket. My guess is the trimmer wouldn't start because of the stuck metering needle causing it to be flooded. There were no bubbles around the fuel supply inlet even with a high pump pressure. Its a simple basket ball pump so it doesn't actually give pressure. I'm guessing I put a at least 10 psi. I couldn't unseat the needle.

[@Camocountry1]

I'm dealing with the same problem with the same saw! Idles but soon as you hit the throttle it boggs down really bad. Guess I need to get a pressure tester now. I'm never buying a husqvarna again.! My STIHL saws go and go with no problems!

[@hisnameisiam808]

My husqvarna 562xp after running hard on a large cedar and not getting much of a brake(because we needed to get the boom lift back to the renters) started cutting out and dying when I would try to let it idle. Also couldn't get it started without holding down the throttle or letting it sit and choking it and starting it like normal. Then it would run until I pulled the trigger and immediately die. It was run on husqvarna's recommended gas that they sell. Sometimes I can get it to start like normal and it runs for a few seconds without any choke then it dies. Any ideas? It was broken in last year.

[@Bungi81]

Hey Don, great video! 👍 Thanks! I also use that JB weld for Repairs. It works great, is super strong and you can work on it, like sanding, drilling and so on... Greetings from germany, Stefan

Nice video buddy! Looks like a great homeowner saw.

[@philipmartin2691]

Yes, these are heavy. If I were going to be doing a lot of wood cutting I would buy a lighter saw. However I do occasional sawing so this model is ok for that:)

[@rayevans9534]

Thanks for your video my husqvarna not 2 years old get very little work in your video you failed to mention the little plug on the right side of the return line of the primer. I put the green plug back but it keeps falling out do you think it be OK to fill that hole with glue or those the plug allow the fuel tank to breath thanks from Australia

[@jjparody8257]

That's a super tip. Seeing how that's a OEM Zama with what is essentially a quality control issue, does this change your opinion somewhat concerning OEM vs. aftermarket?

[@donyboy73]

not really, this could just be a problem on this specific carb

Great tip, Don!

[@victorsimone5445]

Hey mate, which brand of saw do you think is the better built, more reliable & serviceable in your opinion? The Stihl or Husky? I’m referring to the domestic type saws as I’m looking to get one in a week or two. I value your opinion on this one. Cheers

[@philipmartin2691]

IMO quality of both brands is good. I have the 445 and after two or three hours of cutting it starts to get really heavy. I think stihl makes lighter products. I can not complain about ten years of trouble free service from the 445.

[@jackfrosty79ify]

[@gorgon9786]

Hi Donyboy! This was a great learning,.. Will trace down my old HQ55, and see if this is the problem.. Also have a 2nd Q. : all blank, but I have a 2015-ish.

[@robertsimard735]

Excellent tutorial. Appreciate you explaining the fundamentals for us novices.

[@matthewsmith6330]

have you ever used nail polish to seal the inlet pipe? ive never had an issue using it even on the welsh plugs inside the carb.

[@johnclarke6647]

I do the same thing but I use my Might Vac at 5#. I just hook it up and pump it up to 5# and leave it on the work bench for 30 minutes. After that, it better still read 5# or I start out finding why. I also check the carb on vacuum, too. To check for leaks, I spray the carb down with soapy water from my bottle of soapy water I keep in the shop

[@abvoyager333]

Hi, I find you videos incredibly useful but i may be being a bit stupid here so forgive my ignorance. What are the three inlets for on the carburettor? My chainsaw doesn't have a primer bulb.The fuel inlet is obviously from the tank, are the primer and impulse lines equivalent to the in and out of the bulb? Thanks, Brian

[@fixitorstripitGardenmachines]

[@loganv0410]

A Note: many US carb cleaners contain some lube oil, so I avoid them when cleaning to apply a glue.

[@donyboy73]

Great tip!

[@sylkelster]

I use electrical contact cleaner from LPS. No lube oil and non flammable.

[@mattfleming86]

The CRC contact cleaner is also a GREAT multi purpose cleaner. It seems to be a little slower drying. The "cheep shjt" carb cleners dont seem to have the oil residue problem. Usually. But you can always test on some cardboard if curious. Greasy residue will leave a slightly oily spot.

[@tazmun]

These carburetors aren’t like the ones that we pulled that inlet fitting off of to expose a hidden screen are they? Obviously what you did worked but I was wondering if reseating the inlet fitting using JB Weld would serve better?

One day my weed whacker started leaking, it was just lying in my truck, it always ran well, and it isn't that old. I tried to order a carb kit thinking a diaphram was broken, but the cost was ridiculous. The carb is a bit unusual so none of the China replacement are the same. I think I might do a pressure test too, it could be just started the same type of leak.

Hello Don. I have husqvarna 450e chainsaw and the purge bulb stays down and hardly comes back to normal/dome shape. I replaced the purge bulb. When i disconnected the return fuel line from the bulb the bulb did not come back to dome shape; however, when i disconnected or detached the intake fuel line from the purhe bulb the purge bulb pops back to normal shape. The newly installed purge bulb does not purge or suck fuel; fuel lines connections are correctly installed. Please what could be the possible issues? Thanks for all the useful videos. Stay safe!
