In this video I will take you on a diagnostic journey of a Husqvarna 550XP II chainsaw that won't start. This video covers the process after we've hooked it to the computer for error codes. #smallenginerepair
@@TheGreasyShopRag I work 2 days a week at a Husqvarna dealer and can confirm they are very reasonable when doing warranty work, especially the battery stuff.
I run my Huskys at 40:1. Every saw I tear down that's run 50:1 the bearings always seem a bit dry! My 550mk2 has 75 hrs on it so far and hasn't missed a beat! Good stuff as always see ya next time!
Try a different oil? I’ve swiswitched to Red Armor at 45-1. Richard Flagg has some really good analysis videos on different oils, with surprising results.
@@daphlavor I use Penzoil 2 stroke oil and can’t say enough good things about it. Works good in any engine even diesel to get better efficiency and keep everything running smooth.
Your work station and tool box is fricken awesome...You sure come up with some great ideas to make it easier on yourself...I'm thinking your brain works overtime during idol time...Love it...
Have one bought near when they came out in 2011. It has been fine, once I read manual that says, flick on/off swich up/down between shutdowns. thanks for your posts.
You repair a lot of Huskies. Is it because you are specialized on Husqvarna or are there generally more problem with Husqvarna chainsaws than Stihls? Great videos- I learn a lot! Best regards from Sweden 👍
I work at a large Husqvarna dealership. Thats the brand we sell the most of but we will work on anything that comes in the door. There is a Stihl dealership just blocks away.
Do you think that autotune run these new saws so close to stoichiometric that the risk and durability of their new product line is inferior to older saws? Or, is that balanced by factors like long term problems from old saws tending to run a little rich?
Hi awesome video, I have a question: my k970 has really high compression, so hard to pull. I can pull fine without plug. Plug only goes in 2-3 thread. I remove carb, remove muffler, no change. I remove top end, it looks ok, no scar on cylinder, 2 small scratches on piston. I remove decompression plug, clean the hole. Still same…any suggestion ? Really appreciate it.
It would be nice to know how many pounds of compression it has to help determine if this is a compression problem or a binding problem. Also, what do you mean you plug only goes in 2-3 thread? Whats going on there?
@@TheGreasyShopRagOn another topic, do you have any idea why the new 562XP Mark II's don't have the grey styling on the top covers, even though most of the promotional imagery has it?
Helló üdv Magyarországból. Én ugyanígy jártam tavalyelőtt, kb 10-15 üzemóra után. Garanciában megcsinálták és azóta jó. A csapágybeszállítóval volt a gond, úgy tudom a Hq azóta beszállítót váltott.
Hi, I'm a 16-year-old boy from Denmark. i have a husqvarna 450. it's like i can't adjust the carburetor even though it's brand new. think it's the saw since I've tried 3 carburetors now. beyond that back fire it. Do you have any idea what it is?
The carb is brand new or the saw is brand new? I assume the carb because otherwise it would go back to the dealer. If you'ver tried three carbs then my guess is the problem isn't the carb. If its backfiring then look at the flywheel key or ignition module.
Well done Scott! But why did this happen? I understand the main bearings have a plastic collar?? Maybe it was an operator problem?ive got one of these saws, & its awsome!! Apart from a tank vent problem ive had no issues, Thanks for a good video! 👍
Maybe low quality bearings but lets just say for a minute that the bearings are the result of the problem and not the cause. Most of the failures are on the clutch side. Certainly over-tightening a chain can contribute to early bearing failure. Dirt ingestion can also cause bearing failure and that would most likely first show up on the bearing with the most stress on it. Maybe theres more heat there than the bearings like. Not sure.
That is what the Husqvarna dealer told my friend when his 550mkII had a bearing failure, he told him that he had seen several...🤷♂. @@TheGreasyShopRag
I get it. I just don't want to fuel the fire-except for that whole making a video about a bearing failure thing 🙂. I hope yours lasts as long as you need it to.@@UpInSmoke54
Got a 545xp given to me and figured it was the coil as it had no spark. Replaced the coil with one from a 550xp. Have spark now and it fired only once and now it only floods. Any ideas?
545 coils do not cross reference to 550's so thats a problem. If you find a 550 coil and it uses a different part number than the one you're replacing then you need to update the firmware in the autotune module.
@@TheGreasyShopRag So if I update the firmware then I can use a different coil? Would any coil work as long as the wires are correct? Appreciate the feedback 😊
Heres the deal. When you update firmware it asks you to select the coil part number from a drop down menu. If you use a coil from a different saw thats not on the list and select any random number from the drop down, then I suppose you end up with a saw that runs like yours does.If there is a work-around for this I don't know what it is.@@joeellestad8912
Getting into a routine and following it is a good way to not overlook something. It doesn't take any more time than just scratching your head and going full speed into a guess, only to have to go back and test things. Now I won't pressure test a fuel line just to fix an oiler issue but I do look into the cylinder. If its scored then fixing an oil pump is a waste of time.
