Husqvarna 550XP No Start or Sluggish-Fixed! 

thanks again for saving me time and money. The name of your shop reminds me not to ball up oil soaked rags and leave them in wood chips in full sun.

Thanks for the video, brought a second hand 562 at auction a while back, never seemed to have much power in the top end, pulled the carby off after watching your vid, that little filter was not just blocked it was full to the top. When i put it back on it was running so rich i had to do 2 resets before it started to run right.

You know there are TWO reasons this is an excellent video. First because of the "how to" nature pulling a carb and putting it back on type thing. But second might not be intentional, certainly not obvious to some but stands out to me is...Autotunes are just chainsaws. The carbs are just carbs. Point that ALL things that go wrong with a saw like that isn't some ""Autotune" problem They are going to have the SAME type of things go wrong as ANY other saw and the repairs should be approached as you did....like any other saw. Just with a few more wires.

I usually never comment, but I would like to say that this is one of the best repair videos out there for me. Not skipping any steps and explaining what you are doing :)!

00:25 “Yeah, they’re not supposed to do that.” 😂😂😂

Good video ..think my 462cm is in need of carborater clean...likes to run lean so have to recalibration it alot ..the 500i just eats gas it's incredible how much it eats.so on removals I tend to grab 462 wich has carborater and sounds superior way chainsaw should .with bark box ..the best saw and tool I've ever bought and what i started my buisness with is echo 2511t..cleared out 6 acres and lake sides with it still going strong 💪 5 years later.6 pounds and cuts 70 percent of most tree jobs before needing big saws .modified of course ..stock is just to restrict ed ..all the epa lies ..to control the consumers

I had exactly the same thing happen to my 550XP Mk2 only 2-3mths. back. Didn’t ask for a warranty work but before I dropped it off for repair. I made sure it wasn’t the plug, checked the fuel tank filter, checked for debris in the tank, air filter and pulled the muffler to check the pot+piston. I’ve only ever run my saws on Aspen but perhaps I’ve not been as careful as maybe when refuelling. Sure I clean the cap before extracting it from the tank and try to ensure no debris or water residue enters the tank when filling. Even brush off my sleeves & gloves before extracting the cap. Apparently the gauze filter had a gel like blockage. Looked good until held up to the light. So they cleaned it & blew it out and all is now well. It was a relatively inexpensive repair and didn’t take long.

Pretty Good Running Saw 😀

Hi great video congratulations, I have a 545 mark I which does not get current to the spark plug, do you have any suggestions, something to check. Thank you

Probably motor oil. Still know guys that use car oil for gas and bar. Great video

nice video just got a 550xp-g mk 2 this morning

Very nice video with clear instructions on how to work on the carb. Just came in from the shop trying to get my 550 XPG to work again. It just stopped this weekend and the issue seems to be something in the carb. All fuel lines are fine what i can see and the bulb fills up but cant get the fuel to the cylinders. I took the carb apart and noticed the mesh-filter was clogged up, try to clean it as much as i could but still no fuel to the cylinder. Do you have any guess? Thanks and sorry for the "english", from sweden.

As usual, great video and it's helpful to see a pro assess and efficiently work on a saw. That saw looked almost new and off the shelf. Changing the subject, do you know why the Husqvarna engineers added the purge/priming bulb to their newer saw lineup? I ain't complaining, sometimes I wish my 372 and 390 had'em.

Thanks, got me running again!

Thank you man, very helpful !!

Very good video.

This is great, thank you so much! I also have a 550 XP that will not run and I am figuring to try the repair that you perform above, micro screen in carb. replacement. My 550 is much older and has a lot more use on it. So if I do go ahead and take all the above apart what else should I replace while I have it apart and is there a kit I should get first for all those parts? Thank you again, so helpful!

Thanks for the great video! I have 550XP for a repair, as it wasn't running smoothly. When I took apart the carb, the membranes felt stiff and the gaskets were falling apart so I replaced them. Now after putting the saw back together I can't start it as the fuel won't get to the cylinder. The fuel filter seems fine and I've also changed the primer bulb. The fuel seems to get through the carb but not out of it. Do you got any idea what might be the problem? Could it be the autotune thingy? Thanks for help

If there ever was a time I wanted close-up video, this was it, especially on carb repair. @5:20 it looked you put a new something in the carb after you cleaned it out and started to re-assemble, or did you actually put same parts back in?

So you're saying that all that black crap in the micro screen is stuff that passed through the fuel filter? No possibility that this could be from the inside of the fuel line, it is black? Awesome video, the things that make you go hmmm!

Husqvarna does have good airfilters..stihl all mine newer versions it's 200 bucks aftermarket filters and parts are a must to have them filter and run long-term..oil airfilter s are a must. And aftermarket suspension buffers.and like any saw a better exhaust. Aftermarket muffler..Husqvarna makes it difficult but are now available. Thanks to interweb

Great video! I have 550Xp mark 1 and after i start is running, but if i want to accelerate fast when is cold Is doing the same like in video presented.....i accelerate slowly few times and after no problems occur ... she accelerate fast without sluggish. What can be and what i can do in case is need it.Thank youuuuuu!!!!

Ethanol damage to the fuel hose? It looks very similar to the same problem I've fixed on old outboard motors

That fuel filter looked good (new?). Any chance that was changed because of the problem the customer was having?

The 550 XP M2 I have has an oiling issue, the volume coming out seems good but running down the side of the saw. I saw a video of a gentleman who goes by iron horse who actually used a Dremel to make a deeper channel for the oil to flow through to get to the chain. Have you ever come across this situation or recommendations. Thank you.

I got a 550 mark 2 that has a problem whit vacuum in the gas tank in the winter time. Not realy a big problem but kindo enoying. Do you have a quic fix?

Who makes that awesome screwdriver at 6:10 ?? Thanks

Found your channel . Can you tell me why the 550 mark 1 had hot restart issues or what was changed in mark 2. Even with opening the covers and eliminating the primer we still have problems. I'm talking about the jonsered version.

Do you dump the fuel to check tank, sediment,etc? How much labor time would you bill for this type of fix?

What’s it mean if it barely idles and revs up bad ? What do I check

is this dirty fuel storage or ethanol damage

550 xp , wont start the mechanic sais bad electronics could it be?

Customer failed to mention they accidentally put bar oil in fuel tank , and then a shade tree fixit guy rinsed it out changed the filter with the wrong one, charged customer $75 and saw only ran for a day before the black goo in the fuel lines clogged up carb. Hope you charged him $100 for being dumb and trying to get off on the cheap for his own boo-boo!

😂 warranty..only companies I've seen honor thar are echo and of course fiskars wich a simple picture and no question s asked.from fiskars ..local echo dealer has great warranty. We're as my sthil husky dealer no such thing .especially on top handle saws ..1000 bucks for 201t cm ..3 month warranty one year on big saws .if not for it being best supplier around and 5 minutes away..wouldn't buy anything there.they quit selling the mark 2 t540 gas saw because everyone came back. But stihl warranty is a fairytale. 😂
