- Like the title says, a customer brought in a Stihl MS271 chainsaw because it wasn't running right. What we find is way worse than the customer could have imagined. #smallenginerepair

Everyone over tightens their chains. Great diagnosis!
I am a Norwegian viewer. I just bought my first gas chainsaw. An old dirtcheap HQ550 XPG. In addition, I repair two chainsaws for my brother. HQ353 and HQ445. Fortunately, the correct gas has been used and the air filters have been cleaned correctly. Otherwise, there are many similar problems with my cases. I have downloaded the parts diagram and repair manuals but your channel is #1 on youtube right now👍
Thanks! and thanks for watching!
Said before, your an honest mechanic. He should have brought it to you a while ago. Wonder if cheap filter. Great job.
Thanks and thanks for tuning in every week.
I was confused. I uploaded the wrong thumbnail but fixed it now. Yes it may have been a cheap filter but who knows, maybe they ran with it loose or off.
@@TheGreasyShopRag common sense, but I wonder how many saws I’ve checked with bar on. Thanks for showing.
This looks like an expensive mistake, and a example of what not to do. The 2 stroke oil discussion lately of the lubricant qualities or lack there of. This information is eye opening. Thanks GSR
Thanks for watching!
Well done video with good explanations. I just found your channel. Subscribed and am going to look for a good tune up video and carb adjustments using a tachometer. I’m a chainsaw carver and firewood cutter too and am hard on my saws. 9 Stihl and 1 husky and I do all my own work (so far nothing has been beyond my skill level - but probably will have an issue tomorrow now that I mentioned it.
Yep, you just jinxed yourself but I appreciate hearing from you. Thanks for watching!
Great find, Scott 👍🏼
Thanks for watching!
I have had several ms271s and I would run them a while and trade them in on new . Pretty good saw for the money . But they don’t even compare to a ms261 .
That seems like a good plan for a guy that puts a lot of hours on a saw. Get some trade in value while its still worth something (whole). They sell well as parts on ebay.

Poor maintenance bud on behalf of the owner,pity its a nice lookin saw
Ya its done and wont be repaired.
Kickass video!
Carver, I run chains loose. I see a lot of people running them super tight. Now that you showed that, could over tensioning the chain actually cause premature bearing failure?
Yes it certainly can.
Awesome job!!
Thanks for watching!
Intake dust is not a saws friend...I'm guessing owner needs to learn how to keep his chains sharp at all times...you need chips not dust...LOL
Ok Scott a rookie question. On the piston how do determine between excessive wear and actual metal transfer, would you physically have to feel it ? From the picture you showed how did you determine it was more wear than actual scoring. Of course i realize experience helps significantly but just a curiosity question. As always another fantastic video brother and thank you. Take care sir.
I guess it depends on whos doing the talking when you're doing the listening. In other words, the same words can mean different things. On the intake side of the piston heavy wear would appear as a shiny surface on the piston skirt. This is from dirt and any original machine marks will be gone. On the exhaust side I consider heavy wear to be any vertical lines that have no depth...you can't feel them but they are visible. Sometimes only as different colors but sometimes as what appears to be lines. Heat, dirt and carbon could be contributing factors. Scoring is vertical lines or grooves and metal transfer is the same thing only worse. Metal is being gouged out and transferring between the piston and cylinder. Heat and lack of lubrication and/or an expanding piston can be contributing factors. A foreign object could also cause this.
When I see a piston/cylinder with "excess" wear I have to start determining if repair is a worthwhile effort. Most of the time people want to just get as much more use out of it till it dies, then replace the whole saw.
@@TheGreasyShopRag that helped allot Scott , I hate to keep hitting you with rookie questions but I do thank you very much sir. You take care brother.
@@drmikeyb1 Thanks, later.
Poor guy should have bought a Husky! 🤣🤣
He should’ve bought two stroke oil for his gas also. Engine is sad.
Saw would maybe be fine if he maintained it! Combination of Stihl ultra and dirt ingestion will do that!
I really wish I would have seen the other air filter. I'm sure it would have told the rest of the story.
Do you charge the customer a diagnostic fee or is this no charge?
Do you work for free
Yes he does unless they buy a new saw from him.
You see it's like this , this guy runs a business he is not some guy giving out favours for friends. And you have to realise , say there was 10 people a week wanting something looked at and he spends maybe 2 or 3 hours on that and if it was free then no pay for him also he may have a busy little or big shop with other demanding customers waiting on there machines so therefore less time spent on them also so he may have to phone the odd customer whose machine was promised but he could not deliver as he was looking at these other machines for free . Also him being a business, well that comes with overheads . I.e rent , electric, pay to employees and him also. What I will say though is I bet if the customer goes through with the repair there will be no diagnosis charge and if he doesn't sometimes he gets a new machine and a better deal would be given or he may have to pay for say half an hour of the mans time as like I said that time could have been spent on someone else's machine. Or they don't come back and pick the machine up as some people don't have any use for faulty equipment. That is why not free . Have a little common sense . I bet when you go to wherever you work you get paid. Well that's his work. And be grateful for the knowledge he shares and who knows you may be able to diagnose your own equipment thanks to people like him . And honestly the ones doing this on UA-cam with businesses don't do it for free even the guys porting saws can charge up to 400 a time
Good job
Thanks for watching!
Nice Find I’m Surprised The IGN Coil Didn’t Take a Hit Too Those Saws are Usually Not Feasible For Repair Vs Buying a New One Dirt Ingestion and Torn Intake Boots On Those Saws 😐😐😎😊👍🏼
Not working at a Stihl dealership I don't really see many new ones. Are torn intake boots common on newer Stihls?
@@TheGreasyShopRag The 170’s 190’s I’ve Seen a Few The Commercial Guys Buy Them Sometimes Cause There Cheap Homeowner Units There not The Made In Germany Magnesium Case Saws That Require a Case Splitter and Not Made For Daily Use All Day We Are Stihl ,Husqvarna and Shindaiwa Dealer 😀 The Top Anti Vibe Mount Bolted From The Handle too The Cylinder Goes Bad and Allows The Saw To Torque When Doing A Cut and Stretches The Boot and After a Few Getting The Bar Stuck and Pulling The Boot Tears And The Saw Has a Lean Scoring And Or Dirt/sand Here in Florida Ingestion
That torn boot sounds a lot like the T540's I've seen that get pinched and yanked on.@@chrischiampo7647
Say what you wish about Husqvarna, but their filtration systems are far above Stihl imo. Seems like this one might've been more due to neglect, though. Good video!
Maybe. Its hard to say without seeing the old filter. Then again, the spark plug and fuel filter were "due".
I dont think the newer stihl filters seal real well around tje carb. I always smear some grease around the seal to make sure no dirt gets through
I know a lot of thought must go into designing a chainsaw but sometimes it seems they didn't think quite hard enough.
Been tinkering with one of these off and on for 2 weeks everything from coil to carburetor still not right. Think they were junk out of the box.
@@TheGreasyShopRag maybe some of thes companies should farm out the filters to some of the good aftermarket ones like red beard saws and westcoast saws and have them produce them...
@@Countrysawshop21 i got a 271 that i opened up the muffler and it is my go to saw. Never let me down. Probly something little you missed while working on yours. What all have you tried so far?
They already farm out parts. Filters may or may not be one of them. The problem isn't usually with the media, rather the seal to the base as you pointed out. Having said that, choosing the wrong micron filter can cause damage to a saw. The felt ones are typically for the dustiest conditions. Then there can be varying grades of mesh depending on conditions. A filter designed to not ice up in winter can allow too much dust to pass in the dry summer.@@randykeech3557
I have one of those pieces of junk . Can't give away 😂😂😂
Thanks for watching!
Can't save em all
True dat
Wood fiber ingestion is bad enough, but dirt and bark grit are killers.
Yes sir. Thats why we always have to send pics of the air filter and intake when making a warranty claim.
I like your video neighbor LATER
Thanks for watching!
I hope I’m not annoying you by asking the same question you’ve answered a million times, but do you prefer Husky or Stihl?…as far as quality of saw.
In my opinion, we're talking about the top two brands. I like Husky but am not saying they are better. If you're trying to decide between the two then I suggest finding a dealer you feel is best. The right dealer can make the experience acceptable even if the saw has issues.
“Burp!” Dirt indigestion… 🤢🤮
This saw couldn't burp it out. Thanks for watching!
Stihl ultra.... guarantee it.
Are you saying the oil was to blame? It may have been a contributing factor but we can clearly see dirt ingestion. No oil can prevent dirt from ruining bearings.
@@TheGreasyShopRag I commented before I saw the dirt in the intake. But I still bet it played a role being that most Stihl dealers push that garbage.
Is the Ultra oil the one that is not FD rated?@@WeSRT4
@@TheGreasyShopRag Exactly
@@TheGreasyShopRag BTW, if you aren't familiar with Echo Red Armor you should really take a look at it.
