Put on new carb, primer bulb, fuel filter, spark plug, and new fuel lines. NOTHING. Took it to the shop, they to,d me it was a piece of garbage, and handed it back to me. I watched this video, the exhaust screen was totally plugged, I cleaned it, my trimmer runs better than new. THANK YOU so much, saved me $200.
As a professional you really didn't have a choice but to look into that. People like you are what brings business back. Good job.
except the cheapo customer probly wont want to pay for it.
Having a ‘pro’ do a repair and costing half of what the machine is worth doesn’t make sense. I’ll do what I can to repair it myself doing whatever research I need. After being screwed with a mower repair from the engine surging and having the issue come back after a month of use.. never again. $300 mower with a $150 ‘repair’...
So true! I wouldn't just Let it go either, it's what customers would expect. That's the foundation of a small buisness, CUSTOMER CARE.
@@Treyk901 you can't always blame the professional for that though. Sometimes the manufactures pricing structure makes repairing a unit simply not cost effective. Keep in mind most of the time, labor pricing is subject to local market value. So why would a repair shop cut their pricing if they don't have to? It simply the law of supply and demand.
I mean don't get me wrong, your approach is great if it works for you, but most folks don't have the time or interest in fixing something themselves.
But the repair to replace pricing ratio is what it is in most cases due to the manufacturing pricing structure. Repairing a carburetor on $150 piece of equipment is the same as on a $650 piece of equipment so why would the labor be less on a cheaper unit?
@@seanperdue232 yep just because they bault a 150$ power equipment not my problem labor is the same amount of time no matter what!! Go buy another they are trow aways at that price for real ! Don't expect a 20$ fix for your cheep Junk !!
I learned a thing. I quit having issues when I started using non-ethanol and synthetic 2 stroke oil. I never knew there was a screen in there. Can you imagine how many of these went out in the garbage because they did this? THUMBS UP!
millions. 4 stroke gens too. ethanol is a disaster.
@@wim0104 so true, i mistakenly put 85 ethanol on my 68 Slant Six Dart. it ran but as soon as i was at half tank i put regular gas till I reached my destination 150 miles away. now it has non ethanol and running fine.
wim0104 disaster.
my dad brings them home from the dump. most just need new plugs. Amazing people just throw them away. We have so many weedeaters and lawnmowers were dumped
I can, in my area I salvage the garbage trimmers, clean the carb then donate and sell. All because dirty gas, totally believeable.
Thumbs up for being a stand-up repair guy. Nice to know there's still guys like you doing right by your customers.
I’m halfway convinced youtube was listening to me try and start my weed eater and suggested this video
Wow same here
Always listening
Spyware
Me too!! Lol
Haha, same here folks, started bogging down when I fired it up this spring, now I know what to look at!
You are a very good at what you do,we need more honest repair and service mechanic men like you in the field THANKS 👍
Torque specs for small screws is 1/2 turn before it strips
That the correct torque requirements.
Or two turns after it gets looser
I've always used 0.500 rev before it strips. I'm very technically oriented.
It is the same torque as they use on the passenger jets at the factory. Tighten it up until it strips the back off half a turn. 🤭
Iv heard a "General rule" for tightening Any screw or bolt is = 500 ft lbs Plus a 1/4 Turn,
ESPECIALLY On weedeaters
Tight as you can get it. Then 2 full turns!
Your knowledge on 2 stroke motors is obvious... kudos to you my friend for a great video and problem resolution. I get so frustrated with 2 strokes I can’t even put it to words. Keep up the good work brother!
That was nice of you to fix that man’s weed eater so his wife can use it.
lol
Lmao
Comments like this are what gets people through a quarantine. Thank you for doing the Lord’s work. Lol
My neighbor said he lends his other neighbor his mower and HE mows his lawn for him.
my heavily endowed ex (F cup) wanted her garden tilled so i brought of a rototiller and beer and i watched her bounce for like 3 hrs (it was a moment in my life i wont forget).
This gentleman takes professional PRIDE in his work, oddly it’s a dying tradition in this country. Awesome job Sir, I appreciate your sharing this video.
Dying via designed obsolescence & out-moding. Big tech hates the trades class...
It's also a dying tradition because we have become a throw away society. If something breaks we throw it away and get a new one. Often because it cost the same or close to the same to fix it as it does to "just get a new one".
Thank you so much! My trimmer had the exact issue, started easily and good idle but won’t rev or make power. I was ready to toss it and came across your video. I removed the 99% blocked screen and sandblasted it clean. The trimmer runs perfectly now!
The world is a better place because of people like you who share advice and help others.
I love it when a plan comes together!
Hey man I really did enjoy this video thanks for taking the time to teach me something. I'm looking forward to your maintenance. Keep up the good work 💪
I think you just 'solved' my problem with my leaf blower and shrub trimmer! And I need a new bulb too!
I have 5 paperweights that need that.Thank you.I bought new fuel line and filter kits,but never thought of the dang screen.
I think I have at least one or two..........
Great little vid .I love strokers ,simple but very clever principle. Great on a bike. The smell they give you is addictive! Cheers.
I remember my days at the ole Homelite shop in Sunny Buckhannon WV working on OPE. The things you would see come in at early spring would make you giggle. Best part is when they bring it in for a mud dobber's nest in the exhaust hole LOL that is just priceless.
Better yet.....when they bring something in and you can't fault it and after talking to them it turns out to be an operator error......l know as a person you can't be expected to know everything but sometimes l wonder if you can't work this out then how do you have to brain power to manipulate a motor vehicle through traffic to get here?
I think you just saved me from another Rumple Stilskin style driveway tantrum. Thanks!
brake cleaner is also great at finding cuts
.. It is indeed.
so is petrol, WD40, acetone, and hand cleaner.. ;)
Haha well said my friend, that’s great 😁
Yes for sure you will know where all your nicks and cuts are!
Carb cleaner is even worse becuase it is more acidic, if you get a good amount of it on your hands you will start to get white splotches on your hands,
I LOVE what you did with that starter handle. I've been doing this for close to 20 years and have never thought of that. Thanks for posting.
That's how you tune a 2-stroke low-end weed whacker motor!!! Well done! I tried to fix my neighbor's like I work on my 2-stroke motorcycles, but the budget was $0 so I gave up after 4 hours and 10 tools on the workbench. This video is pure satisfaction!
Oh, the power of suggestion!! When you started spraying that cleaner with the camera in close up, I swear I got a strong wiff of the stuff! Pure suggestion - how powerful it is. Nice video, thanks.
I've got an Echo SRM 225, so I found this video very helpful. I repaired an Echo SRM 225 for a friend that had the piece between the engine and the carburetor cracked apart. I now can't remember what Echo calls this piece, intake insulator, I think. But it was the cause of a "won't start" situation he had with this machine.
I like watching your videos, sir. Very informative. I once was a mower mechanic too, until I couldn't see the little things anymore. But I still love it.
I love watching a expert at work
I'm going to try this tonight when I get home. My ryiobi started that same crap last year towards the end of the grass cutting season!
Nice video. I had so much fewer problems once I switched to Small Engine Fuel in a can. If we have to be forced to buy ethanol fuel for our vehicles, it’s nice there is an alternative for small engines. Keep up the good work! 👍🏻
You did what's right the first time and that's all a customer can ask for. I applaud your integrity!
This helped me, I’m going to try and fix mine. I was already thinking about replacing it. Thanks.
EXCELLENT Well documented NON VERTICAL VIDEO! Kudos to you Sir.
I know that a vast majority of people do not have the tools or patience to do these repairs, I have the tools but need to buy a tub of patience. Lol. Thanks for sharing.
Stacy Cornett that’s what marijuana is for. Instant patience 😆
@@fringestream990 , I can't and won't touch that stuff. But I'm sure once I retire, I'll have all the patience I need. Lol. Plus a little liquid lubrication helps: ie Miller lite or Michelob.
Good video.
I subscribed.
I've been a small engine mech for a long time, except for the past ten years when arthritis started kicking in on my right shoulder. You did exactly what I would have done.
1/2 hr work and a little dust off and she's back out to the owner.
@Syd G honestly it depends on how the customer acts.
If they're nice and chill, not trying to rush me, I would definitely check the air filter and blow out debris and such.
If they're in a hurry I'll do what they ask me to do, get it running -if it runs at all, and call them to come in for pick-up or to talk about further repairs lile carb cleaning and rebuild, fuel line and filter replacement, starter rope etc depending on what it needs.
And Never -Ever run a bill up on a customer when they don't ask for extra work to be done.
Shout out to you sir...your video helped fix a go kart for my daughter this weekend after much frustration and troubleshooting. Grateful from Australia
Thank you for sharing this video on to replace the fuel primer bulb and troubleshooting the exhaust screen clogged... 😊
I think you just solved my issue. I haven’t used my edger in 4 years.
This video was awesome sir! I will be sharing this channel! I have a several year old SRM 210 straight shaft unit...LOVE IT! I look forward to doing PM and repairs on stuff when I know what I'm doing! This was an EXCELLENT explanation of how to troubleshoot and address the issue. AWESOME!
I'm sure this will resurrect my last trimmer I set aside in the shed, it was acting the same way. I had a brand new trimmer motor around that I bought for the chainsaw attachment so I started using that one. Now I have a pretty good idea where to start when I get around to working on the old one. Thank you so much!
Well done sir great video once the screen is out i always check the exaust port for build up a lot of times carbon builds up there i have found that many times . Pull the cord up till the piston is blocking the port past the rings carefully chip the carbon build up away with out gouging the piston
I too 100% love my screwdriver kit..I have..that is exactly like yours...they also have the torx bit driver also...that looks exactly like the screwdriver one..except the end is red...
Kennynva - I have both also. Great for smaller components in coffee and espresso machines.
Great video! I have an echo weedeater and couldn’t figure out why it wouldn’t idle up when I increased the throttle. Now I know why and fixed it in 3 minutes. Saved me a lot of time and money. I almost was fed up with it to the point of taking it to the dealer to get it figured out.
I have an older Echo curved shaft. It was a roadside find. Put a new carb on it. Got a new trimmer head and used grass deflector off e bay. This is my go to trimmer, I heave 5 string trimmers, this is my favorite. I fix these and do sales, every one wants an Echo. No gots, the only one I’ve ever seen on a curb find.
Yeah, he got a free repair for the price of a part... Customers love to distract with something small. ANyway, you helped me save my trimmer. I was going to change the carb..... thanks
Not really. Installing the part takes time so there is a labor charge involved. Due to the fact that this guy is an honest decent mechanic he has a half hour minimum labor charge and doing something as simple as cleaning a screen was well within that half hour even after replacing the primer bulb. It’s called doing good business and will more than likely bring more business his way as opposed to simply replacing the bulb and sending it back to the customer in non working order.
Thank you sir for posting this, my echo trimmer is behaving the same way. Will check to see if that screen is blocked.
Thank you for the heads up on that exhaust screen.Also on the carb cleaner.Thumbs up.
Thanks for the video, I've fought my craftsman for 3 years now and that was the problem, I think I've been over mixing my gas. The screen was my problem. Thank you for saving me from drop kicking my trimmer across the yard!!
any two cycle engine , this can happen to, I used to take care of a fleet of blowers and my own equipment had to clean out the exhaust every 10 to 20 hrs. thanks for reminding the masses about this.
Also better two stroke oils are available to minimise this problem, often at a more economical ratio , my two stroke engines are all running 25:1 oil mix and don’t smoke or suffer ....
I'm an Echo dealer. I've seen mud wasps get in things an fill them with mud trying to make a nest. Hard to see unless you are looking in the right place.
Same thing happened to me...I thought I'd never figure out why my normally very reliable trimmer would not start.Mud daubers had built a nest in the muffler; I cleaned it out and it fired right up. Who would have thought THAT would happen?
@@david9783 You learn all kinds of weird things in this business!
We get frequent carb problems here in asia caused by wasps plugging up gas tank vent tubes or carb vent tubes. I even had a red ant nest block up the air filter in my FZ09
@@theravedaddy Now brother,THAT is something to rave about!!!
Seen that also. One reason to leave the clean screen on otherwise they end up doing it in exhaust port. Many years ago I had a mouse nest in my dirt bike exhaust, buggers clogged it up bad enough it would not start.
Wow so glad I saw this. Thanks a million for showing this! Even tho it’s a year later. What a saver. I never knew of checking the screen in there. And you’re so right about doing what you did and said so this customer would be happy. He wouldn’t have known. He must have been grateful! Kudos our friend. Saw a couple more of your videos & had to subscribe. Great stuff. Love doing this.
Excellent video, sir. I especially appreciated the close up shots so that I could really follow your instructions. You are a natural born teacher. Your knowledge and skills are first rate. Thank you again for sharing your work.
Glad it was helpful!
my huskey is doing the same thing! 11 years old! thought it was the screen, thanks!
I cant understand why anyone would take stuff to a shop when they think it only needs a primer bulb. Youd think they could pop one in themselves. Thumbs up video.
If it bust during the time you are running the unit or you have used the unit in the last couple of weeks you right a customer could replace it themselves with the total confidence that it will work like it should or did! I COMPLETELY agree with the customers trying i love selling primer bulds. BUT IF you haven't ran it in months and you try to use the unit and before you could get it to crank it bust ill c u at the shop!!!!!!!
Maybe their TIME is more valuable.
You won’t believe how many people bring primer bulb and pull string replacements to my shop. It’s surprisingly staggering.
@@LOUROLDDAN, its simply because most people are not educated on fixing things any more.
@@NitroGuyJH make that money sir
Thanks for the info...Had the same problem with my front door, took the screen out and doubled my flow! It works on everything!
I am a cabinet maker that doesn't know a lot about small gas engines, till now! Thanks!
It even idles better. Great video. I,m subbed Thanks
"I got the... shaft - of the trimmer... softly clamped in my vise." 🤣 Sorry, my inner 14 year old just fell apart with that line. Well done!

@@THEMOWERMEDIC1 No sir but you never know what people are into!
Hey IRWIN Reps.. Vise-Dick
Yea it's only a two stroke. Ha ha ha
well done. nothing like an honest repair man.
I have worked on many a small engine since I was a teenager, and have people tell me they have the same problem revving up their small engine. I'd say over 90% of the time, it's due to exhaust blockage. People should realize, these engines need service at least once a year, even if it's just a plain old going over tune up, and check for un-wanted wear and blockage. Nice video, and well laid out.
My stihl gas leaf blower did this , I found a dirt Dobber made his home in The exhaust !! Lol
Dang, I didn't think I had any microphones around me several days ago when I mentioned the weed-eater bogging down to my mom. Guess I was talking too loud.
Invidious Ignoramus you think that’s bad, I’ve never even talked about it but recently my side by side has been shutting off when I hit the gas after first starting up. Getting to the point I need to just burn my phone and go back to telegraph.
We are listening!
I Did, TWO Down,I spaced.
This is a very good training video for the lamen...I also am certified with Echo and this is one of the primary checks for basic operational testing...Good job... A carburetor needs to breathe and exhale just like a person...
Excellent information along with a great presentation. Thank you!!
Problem with that precision screwdriver is that the bits can get stuck in a fastener and well fall out in to the abyss when you go to pull off. Also the end cap loves to jump off and drop the rest or the bits into the abyss. They love to hang out with the 10mm.
I have three or four nut- driver type screwdrivers with the most-frequently-used, replaceable hex-bits semi-permanently stuck into the tool with a little bit of sticky putty. I generally prefer that nut drivers, and magnetic bit holders for use with cordless screwdrivers, should have both a magnet and a little C-clip built into the socket, so that the bit stays in place and might even snap-in so snuggly that I have to grab the bit with pliers in order to pull it out and change it. It can be difficult to find nut drivers that have both the best possible strongest magnet built in as well has the Locking C-clip for the screw bit, but the sticky putty is a good compromise for use with those screwdriver bits and nut driver handles that would be most frequently used. Alternatively, you can you some electrical tape to hold the bit in place, but that stuff always starts melting and slipping off and leaving tape adhesive on the screw driver shaft and the screw bit itself.
I've got the same exact screwdriver plus a torx version and I I've never had any of those problems. I also use mine for smaller projects.
😆😆😆 "the 10mm" and the 13mm. You could have 10 each and still couldn't find one when you need it. My socket rack always has some empty spots.
Mark Bingham the 10 mm is so elusive.
@@kermitbearden7142 stop lying! its the 12mm that elopes with the 10mm!
Fantastic video Mr Medic!! THANK YOU!! I am now a sub....
You take pride in your work, I can see it gives you anxiety to let something go out of your shop that isn't fully fixed, even if the customer was unaware of the problem to start with. If I was the customer I wouldn't want you to feel guilty about upselling if it really needs it (as was the case here).
Very helpful. I’ve always hesitated doing small engine work. Great explanations!
Simple, and fixd my trimmer sub'd also
Loads of help, you got me going again, thanks!

Good customer service. Stay well, Joe Z
I have an old echo 302
chain saw it has the same problem, i think the Exhaust screen is plugged I will let you know or what do you think
I just popped the screen on my stihl leaf blower with a Phillips screwdriver! Notorious for them to clogg up. I just insert screwdriver that fits n tap with a hammer till it breaks through screen! Basically a spark arrestor. Not allowed to run on state game lands can cause fire? Lol. Just easy the way i do it. Lol
Nice job. Thank You, Sir :)
Thanks for the video. I can't wait to hear the sound of 2 cycle weed trimmer this summer.
My Stihl FS55 has been without a primer bulb for 6 years now. A tiny little bit of ether sprayed onto the air filter and it starts first pull any day of the year. Thanks for the great video. Liked and Subscribed. Keep up the good work.
just made me realise that I have bought at least 2 new trimmers because of that very reason
Well? Did you leave that Screen out or did you clean it. Cleaned out the ones on my 2 steal saws till I finely just left them out. They are flame ares-tors and removal could cause a fire. But use mine in a safe area.
I had cleaned my exhaust screen before. Never had a need to replace the bulb. Good to know it's within reach. Very helpful video, thank you so much.
nice video mate ive had a few with the same problems in the past
keep them coming
Tought i heard someone say they were going to CLEAN the area still waiting for that to happen
good video, maybe while you are spraying the gunk off with brake cleaner, take the time to use a toothbrush and clean the stuck on gunk. makes the job more impressive if it's returned cleaned!
I save all my old toothbrushes, they come in handy for so many jobs. I always have a few with my pipe soldering tools to put flux on with.
I save a couple of my old Sonic electric toothbrush brushes (they screw out and get replaced every 3 months) and put the old one back on for just this kind of cleaning and man, it is fast and easy that way and has so many other uses, too. Then when done, unscrew it and put the good brush back on and brush my teeth.
Soak the whole thing in a 55 gallon barrel of brake cleaner. Clean as a whistle. A bit expensive but, oh well. :)
@@guesswho2378 cool trick gerard, but for less than 5 bux, you can get a cheap electric toothbrush and dedicate it to garage use only.
Good tip
Do you have a toothbrush I could borrow
Thanks. Clear descriptions of thought process to solving the won't rev problem.
Thanks didn't know that was in those. Makes sense. Im a mech an something l love about the career is no end to the new things you learn. One trick to cure wobbling screwdriver is file tip a bit flat allows for better/deeper engagement l find l don't 'turn out' of the screw either.
Thanks for the knowledge
Using the correct size Philips bit, or any bit is key in the first place. I like your tip flattening suggestion as well.
Thanks for posting! Do you think that a blocked screen would also cause a echo backpack blower to get finicky when wound up? Starts in about ten pulls and idle/ high speed does not stay up. Seems to choke and down throttle. And I have to work the throttle to stay going.
Thanks for the opinion.
Jim Pikul yes if it is quite but it sounds like it needs a carb clean if it takes 10 pulls try cleaning the main jet first before you clean the screen
zachattack1479 thanks for the help!
@@jimpikul8551 anytime
I didn’t know those come with a spark arrester. I can’t tell you how many times I saw my old man shatter a two stoke weed eater on concrete for this exact problem without ever changing the spark plug, air filter, or using fuel stabilizer for storage. Then he just went walyworld and bought the cheapest thing they had, again. Fits the definition of insanity pretty well if you ask me.
blake dymond
I can relate to your old man ;)
Sometimes when I'm hired to mow a lawn I don't have the time to mess with it and it gets frustrating.
I've gotten better tho, now that i know what's up
probably the same what was wrong with a scooter i was given, started and idled great, wouldnt rev up or go abot say 5mph, no-one told me it was probably a blocked exhaust (2stroke scooter)
I quit buying 2 strokes for lawn equipment.(Johnson / Evinrude the outboard engine people needed to make power lawn equipment so there could have been quality stuff that was meant to be repaired but I digress).The quality is just terrible on non commercial quality brands 50 hour life cycles just don't cut it. it does not matter if it is an Echo, Poulan, Sthil, Craftsman, Husqvarna, weed eater or any other 2-stroke you see at a department/home improvement store
I have a half acre that has a full lawn and established pine trees along with fruit trees and I get about a year out of these things and they become problematic.
Here in California our fuel contains ethanol and it just destroys these things, I have even dumped all the fuel out and let them idle until they stalled from a lack of fuel hoping this would solve some of their issues (it didn't help at all, we don't have a off season its Southern California so you use this stuff pretty much year round but I figured it was worth a shot anyways I even use Sta-bil in the fuel to help keep it fresh longer).
I am not your average consumer as I am a ASE certified mechanic (not an expert in two strokes although but an engine is an engine for the most part) and I am a hardcore DIYer never hiring out to repair anything. From my experience as a general rule If the primer bulb is bad so are the fuel lines, if the fuel lines are bad so is the spark plug (you can clean and regap it, and if the plug is fouled up the carb is probably do for a rebuild / clean out. Then there is that spark arrestor in the exhaust that is near impossible to clean cooked carbon off of supposing you can get it off in one piece to clean it...Once you replace or repair all this stuff you're out about 80 bucks that it would just cost for a new one not to mention all the 3-4 hours of labor and the risk of breaking one of these little plastic bits that were never designed to be taken off after they were assembled. Just pure garbage.
Smashing it like Jimi Hendrix would smash a guitar is quiet satisfying and your old man was probably smarter then you give him credit for.
No body wants to do a choir just so they can do a choir especially if they worked all week.
Momma used to buy the cheapest push mower that wal-mart sold every year (apprx. $100) Always a pain in the arse with that POS every time I stopped by to cut her grass... it was guaranteed not to run the next year, and the process would start over. I finally convinced her to let me go buy her a mower, and picked up a decent lawn-boy self propelled (apprx $200), and it has been working fine for years. Moral of the story is don't buy the cheapest crap tool on the market. The extra $100 is well worth it, and you can't put a price on ruined weekends where a 45 minute grass cutting job turned into an all day crap-mart brand lawn mower repair job.
barking.dog.productions1776 I agree. You don’t have to buy the fanciest most expensive model for sale, but when you spend $100 a year on cheap crap, why not buy a pro grade stihl that will last a home owner decades if taken care of?
Thanks! I just bought a 10pk of bulbs for my Husqvarna Rancher 455. +1 for the video.
Good job! That should last you til 2069
Thanks MowerMedic1 for the tip on cleaning exhaust screen on the Echo weed eater. I have all Echo machines mostly and they are the next best to Stihl.
I have a Kohler Courage 22 horse twin it has that first turn hard start will not start I've tried adjusting valves what else is there
Mine has done that since brand new for 8 seasons now. I have to manually turn it backwards off a compression stroke to start. It’s really bad when the engine is hot and you shut it off and then try to restart it. Two dealers could not fix it. Both said valve adjustment but that didn’t fix it. Tried new coils and that didn’t work either. It did the same thing every time until I got rid of it. Still runs like a new motor just a bugger to start
How did you clean the screen? That wasn’t shown and is key, IMO. Thx!
I think the correct way to clean the screen is to just replace it with a new one, they can't cost all that much.
Propane torch will burn the carbon off...
@@kebo57 nope . small torch- just few seconds till it glows and see sparks of burnt carbon fly off/ perfect clean.. like new... can add holes with drill bit /fk the commy bastards/ be louder and need re adjusted- but way more 1/3 horsepower
throw it away
Take torch to it. Propane. Burn it and it will ash out. Gently clean with a wire brush. Done
This video really helped me. Too many things I can't fix on small engines. The things I don't know could fill a small volume. An exhaust screen. Never heard of it until now.
Great CLASS, Nothing wrong with learning something. Thanks, looking forward to many more.
This has been a super interesting video, thanx for uploading it man. I've had a petrol strimmer in my shed for more than a decade doing nothing because it won't start at all. You've inspired me to have a go at stripping it down a little to check for some of these easy fixes. Though I have the impression that the little fuel tank has an internal filter which is blocked. I really need it now as I haven't taken care of the heavier growth at the bottom of my garden, and with heavy rain we are getting in the UK this summer it's already growing like crazy!!!
If it's not run for 10 years then a new carb will be required as fuel deteriorates and will block the needle jets and will never get them clean.
MrSnookerballs optimist, he should just warm the carbie and apply a generous amount of carb cleaner to all jets and orifices and any filter screens before tossing out the old carb, often the carb is not bad if kept cool....
Yes, if you don't test it and the customer can't get it to run right, he'll be back.
Yeah l know but surely if the customer specifies "just change the primer cap" then thats all you do, and if he comes back then we start to talk about why its not running well......what do you think
@@laciLaszloM Well, that would be the way a dirtbag conducts business. More than likely the customer may also think, “what a crap mechanic, he could have called me and told me there was another problem with my machine and I would have gladly asked him to repair that also.”
@@InDisskyS131 well thats what lm practically saying......whether its over the phone or in person.....you do what the customer asks and if not working still, then workout what to do next......thanks for replying
M.A.G.A
Mine ran without a primer bubble for about 4 years and I just now had to replace the carburetor so I did a full overhaul.
Great video! My blower is doing the same thing. Got the remedy now!👍
I'm watching this video and smelling the sweetness of 2 cycle exhaust, right here in my office.
That is a spark arrestor. To us simple folks it's called a screen.
to us simple folks it's 5% power robbed by Californian legislation. I usually remove them...don't need them, as I don't live in a fire-prone area where they're necessary.
I also replace my carbs with fully adjustable ones for RC airplane engines, because if I leave the california compliant part on the engines always lean burn and die within a season. Same with the oil mix, theycall for 50:1 I give them 30:1.
If a two stroke isn't smoking blue under load it's gonna die soon!
@@TestECull yep, my dads polan wild thing and weedeater died in less than a year from too lean a mix. Can't remember if it was 40:1 or 50:1 but since then everything is 32:1
@@matthewhoffman9242 All in the name of a cleaner burning tool...way I see it, if emissions matter, use a Honda 4-cycle. Otherwise, let the two-stroke smoke, itt'l live a good long life that way!
@@TestECull yep, also the smoke helps keep the mosquitoes off...
Thank you for this video. After watching this I knew what was wrong with my chain saw and was able to repair it.
I love my echo, I have the 285 and it never fails to start. And this video does help, I have an old weedeater (poulan?) That is doing the same thing, did a lot of work but never took off the exhaust! Reason I bought the echo. Thanks!
10:46 - That stopped being a "screen" some time back.
lol, yeah but, assuming the screen is to prevent dirt and whatnot from entering the engine via the exhaust, it was still doing its job and doing it even better still (blocking the smallest dust particles too).
@@DreadX10 not much is going to get into an engine via the exhaust . It gets blown out . The screen is a spark arrestor
Customer needs to take better care of his tools. I can't believe people can't take 5 extra minutes to clean the crap out after use.
Terry, it's not about taking care. They have no understanding of machines. Plain and simple. OTOH, when a computer goes down, that same customer can't understand why people don't simply do this or do that. I can fix engines, but don't ask me to rip a computer apart...…...
I've worked on a lot of small engines and have never seen a screen that dirty. I was thinking it needed a carb adjustment, but learned something today. Thanks.
I've NEVER seen a screen in the exhaust muffler on a smoke belching purposely rich running 2 stroke engine .. what the hell was someone thinking who designed that crap? .. get that screen out of there, NOW!!!
@@KrustyKlown Yeah, pretty dumb.
I'll take a wild guess and say the guy who came up with it,
was named "Peter Principal".
