Echo SRM 225 Weed Trimmer Won't Start - Why?
Вставка
- Опубліковано 23 лип 2024
- Learn how to diagnose an Echo SRM 225 that won't start possibly due to bad crank seals or leaky exhaust gaskets without special tools. This problem is common for many a 2-stroke trimmer, garden tool, chain saw, strimmer or blower made by Echo, Stihl, Husqvarna, Shindaiwa, Ryobi, and many others. This tutorial can help you to understand why your 2-stroke trimmer or blower is difficult to start or won't stay running. Sometimes a clogged muffler or spark arrester screen will alter the ratio of fuel/air flow on your 2T machine.
00:00 I'm not Will
01:10 Inspect fuel lines, spark plug, and fuel filter
02:23 Remove top cover to inspect spark arrester
05:16 Clean oil and carbon deposits
07:56 Remove recoil starter
09:12 Inspect crankcase and piston
10:19 Poor man's pressure/leak test
14:05 Re-assemble baffle and shroud
The tools I like and use most often:
Magnetic spark plug socket set: amzn.to/3CzmpvO
Tachometer: amzn.to/3sHibiH
Vessel Megadora JIS screwdriver set: amzn.to/363RFqO
Channellock Bent Needle-nose pliers: amzn.to/3I5DbnA
Long 1/4 Quick-connect Torx Driver Bits: amzn.to/3HUNgnm
Spark Tester: amzn.to/3CxW2qi
OTC Leak-down Test Kit: amzn.to/3CyUhJn
Compression Tester: amzn.to/3IWd6sp
Wear your safety glasses, or you'll put your eye out. Try on some gloves. Take off that spark plug boot. Clean your room. Open the windows, those fumes are nasty. Just 'cause I do it, don't think it's the end all, be all solution. There's plenty more ideas out there, I can't take responsibility if you slice off a few fingers after watching my videos. And don't just pour that toxic stuff down the sewer or in the ditch, dispose of waste responsibly. Just be safe, OK?

Just watched it now Stella, you pay for what you get most times, though you can be lucky sometimes.
I bought a SRM 225 years ago used that had a oil seepage problem with the muffler. I ditchED the catalytic muffler for a older SRM 2100 non catalytic and it solved the problem and no more oil mess.
@@jakewells9403 Thanks for watching Mr Jake! I'll suggest that to the lady that owns this. Cheers!
@@rickthelian2215 You are right Mr Rick!
I love watching professional repairs! Great job as always Stella!
That means a lot coming from you Mr Jeremy. Cheers!
Much props to you and how you give attention to detail in certain issues that may arise just like the screws..
I appreciate your kind comments. Stuff like that is easy to miss, and can cause a lot of grief when the wrong screw strips out the threads in the casing. Thanks for watching. Cheers!
I really like the way you explain very patient & concisely
I appreciate you watching. Cheers!
That stop/start switch will getcha every time. Great vid. Same machine I use at my home.
Yep, gets me all the time Mr David.
I’ve found that when homeowner don’t do a correct oil/fuel ratio mix, that usually happens. I just tell them just buy it already mix for you. That way you can not I repeat can not mess it up. Thank you, love your channel
Good advice. Thanks for watching. Cheers!
I couldn't believe the screen wasn't clogged. You have great patience cleaning that weed wacker. Great video!
Thanks Ms Patterson. I honestly believe the other shop just replaced the screenm but didn't clean out anything else, leaving a build up that still restricted the exhaust. Thanks for watching. Cheers!
I am a pretty good DIYer, however, I still enjoy watching your videos and always pick up a few hints & tips along the way. Nice video!
I appreciate that!
Another great video young lady! Your knowledge of small engines, video and editing skills all compliment each other extremely well. I really enjoy watching and learning from you. Thanks for sharing and have a great weekend. 👍
Thanks Mr Steve for your kind words!
I was expecting to see a clogged screen arrester as well I was surprised when it was clean. I can't think of anything else you could of done I think some oils leave more residue behind than others. Great job Stella. Haven't forgot your picture will get it to you soon.
Me too ! Thx for watching Mr Nash
Great video as always Stella. Showing our tricks of the trade I see Lol. We have the tools but seldom pressure test, carb. or brake cleaner is way faster and works great. Thanks for sharing this great, easy to follow tutorial.
Thanks Mr T-Bone. Gotta help where I can. Cheers!
I had a trimmer once, forgot the brand, but the kill switch was momentary contact so it could never be left on which was one less thing to worry about. Good video and its good
to see that Chickanic has some competition!!
I appreciate you watching. Cheers!
we really enjoy watching you cleaning parts... old gas is a great idea... Thanks ....
Thanks for watching!
We’ll I watched your other video and it helped me out. I was all set to go out and get a new srm225 after 10+ yrs reluctantly, but checked out your video and it worked. I changed the carburetor and was priming it too much and was flooding it, kept repeating the mistake a couple of times, cook the air filter cover off let it sit for a day then primed 4x and it started. Thanks
Yay! Glad to help. Cheers!
Nice! Sometimes it’s best to start with the basics, spark, fuel, air and is it clean no build up. Great video
I appreciate you watching. Cheers!
Excellent and very informative video. I just picked up a SRM-225 at a garage sale for 5 dollars non-operative and by following your video and a few others that have to do with carburetor I got it purring like a kitten now. THANK YOU !!!
That is awesome! Thanks for watching. Cheers!
Lawn mower lady- just throw in Dumptser
LOL, I'm trying to save the planet here.
@@TheLawnmowerLady if can fix am up get them running someone could have good piece of equipment to use
I'm still trying to get the brand new ECHO to run/start 🤬😡
I had the same problem with my old Echo but it still ran. Wow nice cleanup. I hate that switch it got me every time Lol. That's is amazing I thought it was going to be something major. You are good. This might have been a small problem, but you taught me something Stella.
Thx Mr Bill. I honestly think the little muffler screeen was just too gagged up. Whoever cleaned or replaced the screen didn’t clean that out.
@@TheLawnmowerLady Your very welcome Stella. Yea that was a lot of oil gunk up in there.
I agree on crap switch
Small engine repair is always a hassle. I put my echo away after using it with no issues. Two weeks later it's leaking fuel. Thank you for this very useful video. I'll be able to make the complete carburator and fuel line fix myself
Happy to help. Thanks for watching!
Junk it
thank you, again, for posting. i like it that you use hand tools. lotta things got fixed before power screwdrivers & impact drivers. i like your voice & delivery. take care. dLLund
Thanks for watching!
Another great job, just keeps getting better and better 👏
Thank you Mr Rooster!
Great video Stella - you are not alone with the kill switch - happens here all the time 😃! Hope to catch up tomorrow on the stream. Cheers!
Thanks for watching Mr Anders. Cheers!
This is a marvelous video. Thank you for posting it.
Glad you enjoyed it!
great video-subscribed...since the only oil in a 2-stroke is already mixed with the gasoline - the only place the oily buildup can come from is there...I don't experience this with my two stroke equipment (including a pair of 225's) and my theory on why is because they don't get babied...running with plenty of WOT gets everything running nice and hot...it can't get clogged up when it is burning cleanly...I believe once it starts it gets worse and worse until a proper clean like this excellent technician performed here
I believe that was the problem here, not revving it WOT, and think the other shop just replaced the spark arrester screen, without bothering to clean any thing else. Thanks for watching.
Enjoyed the video. Thank you from the UK.
Cheers Mr Bigg !
always appreciate a clean machine. thanks for sharing
Me too!
I watched your video yesterday this morning I cleaned the muffler also I beleive I had some bad gas I got some fresh gas and mixed it with echo red armor oil. Started right up. THANK YOU !
Great job! happy to help. Cheers!
Excellent video Stella. Keep up the great work.
Thanks Mr Kyle. Cheers !
Hi Stella great job and a great video I like the way you work on your jobs old toothbrushs are great for small engine's 👍
Thanks for watching Mr Mark. I try to recycle everything 😀
I do not come into contact with the likes of mowers, chainsaws or trimmers and such, but am an engineer (sort of) I found that very interesting. This is the first video of yours, after James Condon recommended you, and I am very grateful to him for that. Will be watching a lot more. Thankyou Maam :)
I appreciate you watching Mr Tony. Cheers!
I've seen buildup from seepage when folks store those echo trimmers hanging with the power head down. When the gas evaporates from the fuel, the oil is left behind. Good video, as usual!
Good to know. Cheers!
So store then engine up? Or on it's side?
@@blakelwhitney engine up if it has fuel in it.
Good stuff Stella. What a good little trimmer
Yep Mr Claus. That Lady that owns it loves it.
You are very thorough, I don't think you missed anything .
In the end, I believe she was just not revving it to full throttle when she was trimming. Allowed a lot of blowby to accumulate. Thanks for watching.
Thanks Lawnmower Lady, your content was greatly helpful 😊👍🏽
Glad it was helpful!
You AllWAYS have a clean work area and that’s very important for good repairs
Ha! Thanks. I think it’s more the camera angle. My little shop is a mess, but I do store tools and attempt to tidy up between jobs. Thanks for watching.
Old fuel is nice and cheap, I keep a 5 gallon can just for cleaning parts. Great vid Stella!
That's why my shop smells so sweet. 😂
@@TheLawnmowerLady I guess we get rid of it when it starts smelling like turpentine!
Great vid taught me something new, thanks for sharing!
You bet! Thanks for watching!
I ran echos for several years. They were notorious on the 225 for that build up and oil seapage. We always had to take the screen out and contantly change the filters. That's why I made the move to Stihl and problem solved. Great video
Thanks for watching Mr Shane!
@@TheLawnmowerLady Your quit welcome. I enjoyed the video. Keep putting that gold out!! Congrats on 1k
what people and landscapers alike fail to ralize that the orange echoe models are home owner use only,the grey cases is for the pro landscaper,the other fact is the srm-225 and 230 as well as others are home depot models not a professional lawn mower shop grade,they have no carb adjustments and we see these all the time with running issues especially when engine is breaking in and rings seat,
@@spigs1967 I had no idea. Makes sense. Thanks man
@@spigs1967 Sorry I disagree on e one point. All new Echo Models are now Orange. I do agree on the point that Home Depot and Lowes do not sell commercial grade units.
That was awesome ! Thanks young lady.
Happy to help. I appreciate you watching!
Awesome video STELLA . Dang thats alot of oil on their ..lol .. Thanks for all the amazing videos . Hope all is well take care & stay safe .
Thanks Doc. It was a mess.
@@TheLawnmowerLady yea i bet
Excellent video Stella
Thank you! 😃
Eather fuel lines , fuel filter..or carb.. yes the screen needs cleaned..I have the same one.. great unit..did a tune - up .. first time in 6 yrs since new..bought the kit...I also have some sea - foam in my gas can..I run through the trimmer.. always..with high tes, 93... Shell gas..no speedway..great video..ty
Right on!
That's a pro job.
Congratulations
Thanks for watching! I appreciate the comment. Cheers!
Thank You for sharing so clearly, I sure feel looked after and very grateful to learn about my Echo. Have saved both link and video to recheck when I have to time to follow your advice without haste. Gosh you are so Good!💐💐💐👏🏼👏🏼🤩🥰
I appreciate you watching. Cheers!
Your very welcome. I ordered the kit feeling very supported by the steps you have shown. Be joyful!🫶🏼🙏
Just an FYI, when first checking out a non start issue start with checking out the cylinder head though the exhaust port and then you will know if you should go forward or if it has actually become a large paper weight. Gas, spark, exhaust, and of course compression is needed for it to run however the most costly being compression. Great video though, keep posting.
Thanks for watching!
Great video! Keep it up and you will hit 100k !!
Hope so Mr Trent ! Thanks for watching and your support. Cheers!
Lawnmower lady as a man I have something to say to you...I really like your show, I mean I really like it 😊 it's fun, informative and the video is well recorded, just a great UA-cam channel . Thank you....
Wow, thank you! Cheers!
@@TheLawnmowerLady He's telling the truth, and I agree with him.
Could’ve been stored with old fuel & the gas will evaporate leaving behind more oily residue then they put fresh gas mix in mixing with the oily residue making the mixture with too much oil. Good video!
Great point Mr Mike! Thanks for watching.
Add not running at full revs to the mix and I think we have the cause of the build up. Worth asking about the fuel mix and how the machine is operated.
Nice video Ms Lady, I love your levels of "cleaning gas", bad bad and fresh bad, sounds like someone I know. :)
Yep, I felt kind of silly saying that, but that first tin was too gagged up. Thanks for watching.
That was the best way to say it, sounded spot-on. 🤣👍🏼🤣
I just received an envelope in the mail, thank you so much.
@@Big_Johns Yay!
Great Job Stella all my echo srm 225’s leak except the oldest one. I heard it’s because the new muffler don’t have a baffle like the old ones did.
Thanks Mr Matthew! No baffle will certainly allow more blow-by to not get burned up.
@@TheLawnmowerLady Correct, because I researched why my (4) newer srm 225's leaked and the oldest srm225 didnt. I have a Husqvarna 123L that leaks I will check into why it leaks.
Awesome quality on the video!
Glad to hear that Mr JB! Cheers!

I learned something new, gas can be used to clean, thanks Stella.
I figure why waste a great solvent. Cheers!
@@TheLawnmowerLady pour rest of old gas in your car, that's what a guy in bethel ct says
I always suggest that to my clients. Obviously I would not do that with bad fuel like this with all the dirt and particulate matter after cleaning all the debris off the exterior of any machine.
Beautiful 😊
Thanks! Great job on the video.

Good job Stella.
Cheers Mr Pete!
New viewer here. Very interesting and educational‼️Many thanks😃

Stella, i don't think you missed anything! Maybe customer is using cheap 2 stroke oil or over mixing it. You improved the cleanliness 100%. Good job as always. I know you have been very busy as i saw you had to go to Raleys Small Engines and do some welding! LOL. 🤣😎👍Roger
Thanks Mr Roger. The owner is pretty savvy about these machines. I think just never cleaned up muffler parts, maybe running often at lower rpm.
Nice fix and tips Stella did you see Bruce make the piston stop other day another one if your tips brilliant x you rock x
Cheers Mr Gary. Thanks for watching.

Just found one in the street 12 dollar new carburetor kit (plug , carb, gas lines , and filter ) runs great, and also if you having problem with gas. Check that the line is broken where its attached to the tank
Nice score! Cheers!
This seems to be a common issue, good to know
I appreciate you watching. Cheers!
Great job Stella :)
Thank you Tom! Cheers!
Helpful video
Glad to hear that Mr Carlos! Thanks for watching. Cheers!
I always enjoy your videos. Always helpful. Thank you.
Is the build up caused by not running it wide open most of the time? I was told it will do that to all of them if you run half throttle most of the time. I know you need to run low throttle for certain circumstances.
Thanks Mr Bud ! In retrospect, I think that indeed was what caused this build-up of un-burnt fuel and oil. I think once these units are warmed up, they do best at WOT. I appreciate you watching. Cheers!
Hey, don't feel bad! My dad was trying to get our Farmall Super C started, I even towed him around with the JD 60, then he discovered he didn't turn the gas on!!
I know my right arm is probably longer for all the times I've yanked on starters without replacing the spark plug boot, kill switch, etc. 😂
This is awesome I wish we were related
I suggest you do your leak test using brakekleen instead of carb cleaner. It's non flammable which is of course safer, and it is safe for your engine as well. It also is immediately obvious when you hit the leak as the motor stops instantly but cranks right back up first pull. I mostly repair and rebuild chainsaws and this has proven to be the best and easiest method of finding leaks not to mention cheapest
Nice! I like the brakekleen idea. Cheers!
I agree with You. It works great
Regular Brakleen is flammable and often used as a substitute for engine starting fluid -
I try to avoid brakekleen on any plastic components. The old stuff can ruin plastic, not sure about the newer formulas.
Is it possible the wrong fuel mix was used
Great job on the video and the repair. Perhaps it was run with to much oil in the mix? It seems to be running great now.
Thanks for watching Mr Brian. I think the owner mixed oil right, but I think it was run too long at too low RPM. Cheers!
I think that a lot of people are just mixing in a “ little extra oil” thinking that more is better. More often than not folks are not able (or willing) to run these 2 cycles at full rpm. Putting these around will cause this build up. I have had great results from using the Echo Red Armor oil. I think it’s way ahead of the old Power Blend Echo oil. It’s not cheap but as a homeowner, you probably don’t use much fuel and oil anyway.
For homeowners, the premixed ready to use canned fuel takes the guesswork out of mixing and stores well.
You're right Mr Andy. That canned fuel takes a lot of guesswork, math, and bonus: no ethanol. Thanks for watching. Cheers!
@@TheLawnmowerLady I’m so glad that I found your channel. I think it’s great to see a lady that is so passionate about small engines. I love helping my coworkers get their chainsaws and trimmers running again.
A good honest cleaning did a miracles on that little engine.
Absolutely. Thanks for watching. Cheers!
Can you make a video to adjust air/fuel mixture? This one is very helpful...
The honest truth is I don't have to tweek them too often if the carb and air filter is clean. But next time I will. Thanks for watching.
Hi, I have just come across your channel. All very good. I watched the one where you use the tecumseh tool to set the float bowl. I live in Scotland UK and have been trying to find that tool here in the UK. It seems that tecumseh parts are not available in the UK. Thank you.
Thanks and welcome Mr Ray! Maybe try ebay for a seller who has that Tecumseh 670377 tool and will ship to UK? The thickness of the tool there is 5.4mm. I've seen Donyboy73 use a 7/32 drill bit to set the float level too. Cheers!
grate video
Thanks for watching Mr Kenny! Cheers!
Hi I have a srm 225 also. And mine started with that oil mess all over right away. The problem is the carbs are set too rich from the factory. You need to drill out and remove the plug covering the mix screw under the primer bulb and turn clockwise lean out the carb slightly. I am doing mine one quarter turn at a time and the oil problem is almost gone. Do not go too lean though!
In the end, I think the owner was just not revving it out, and creating a lot of unburnt fuel. Thanks for watching!
I was wondering about that ... I purchased a 2.5mm 91075 so I can adjust the mix, but I'm a newbie 65 yo woman learning all this great stuff before I replace this trimmer!
Great video I think that is what is wrong with mine.
I appreciate you watching!
You are awesome
Thanks!
Thank you. You give a lot of great tips.
Makes me think possibly the wrong oil /gas mixture but nice video mame. Ill say you sure can clean an engine ha ha
The owner was using it around 1/2 throttle at all times. They were mixing it right, the other shop i believe just replaced the spark arrester without addressing any of the blow-by build up. As much as I complain, bad gas the best! Haha.
Hi Stella I was wondering if you can help me out about a brand new Stihl trimmer last year and I'm getting oil leaking out of the muffler I use true fuel gas any ideas
Thx Mr Shane. Sounds like incomplete burn, maybe some worn rings causes excessive blow-by? What does the plug look like?
Nice video Stella, with no disrespect to the female community we have many single mom and widowed customers that have needed their two stroke equipment serviced every year to get it running. In all cases it has been improper fuel mixture so as a service we mix ethanol free fuel to their required specification with top quality two stroke oil then sell them a litre of Aspen 2 premixed fuel for the last use of the year and winter storage. To date no service on this equipment for carb issues customers are very happy.
Thanks Mr Wayne. I think she might switch to the canned premix. But she seemed prey savvy about her equipment. Maybe just running it too long at a lower rpm.
@@TheLawnmowerLady I think you are right on with that diagnosis Stella.
Thank,s
You're welcome!
Hi, Stella I currently replaced my carburetor with a new kit and gas lines. There is spark. But before I did all this, I pulled and I pulled until I got it running but without letting go of the gas or else it would turn off. I used it for one hour straight and it just turned off. Haven't been able to turn it on. I also cleaned the piston the screen in the muffler and replaced the sparkplug. Can u give me any advice
Thanks for watching Mr Leon. Sounds to me like you need to adjust the low speed screw if it won't idle. On those echo carbs, the low and high speed screw are hidden, and have anti-tamper covers. The high speed screw is under the primer bulb, and the low screw is right in the middle of the top where the throttle cable is attached. I haven't edited a video on that yet, but you can find other videos out there that show how to pull that plug out and adjust the carb. I hope that helps.
While I understand that this issue would have been due to the blow by and machine never being cleaned in years, would the amount of oil that was present possibly be due to using too much oil in the gas to oil ratio??
I don't think so Ms Inisfad. The lady that owns this always uses the Echo oil. I just think build up over the years with a recently replaced spark arrestor screen.
great video stella,as i try to teach other so called mechanics,your only as good as your diagnosis,if you follow the diag procedures which are pretty much standardized in the small engine world and you have common sense then you cant be wrong in your diagnosis of no starts,the basics always apply,air,fuel and spark,if you have none of the three it aint running,i see many a genious at my shop that think they know it all and follow bad habits and dont read service manuals or check for bulletins or other factory or dealer problem run ins,
Thanks Mr Spigs! I appreciate your comments. I learnt a long time ago to start with the easy stuff. Cheers!
Hi Stella good video, you did everything much the same as I would have done, even the poor mans leak test👍 Also forgetting the kill switch, I’ve done that 😂😂 I wonder if they have been mixing the fuel to strong, to much oil as I’ve had that on tools before especially on echos, that’s my theory anyway. Thanks for the video🙂👍
Thanks for watching Mr Luke! I honestly think the other shop replaced the spark arrester, didn't bother to clean it up, and the owner prolly had a habit or running it at low RPM. I explained this to the owner, and hopefully it run well for the next few years until the fuel lines start to go. Cheers!
I am surprised that a big repair shop didn't clean it. Must be getting paid flag hours.
Hi LL. I have a problem you may be able to help with. A neighbor brought his Echo 266 edger for me to repair. I checked it out and there was no spark. I diagnosed it as a bad coil. I ordered an new one and installed it. While installing it I noticed that each screw/bolt that holds the coil in place has a plastic washer/spacer as well as metal washers. One of the plastic ones had degraded and in fact broke in two while installing the new coil. I had some small plastic washers (wrong size and not made for use on a small engine) handy. I tried one in place of the original one. Being the wrong size and not intended for this purpose it squished and distorted when I tightened the screws. The engine will fire up now & then but won't stay running. I think that if those plastic washers were indeed intended as electrical insulators then the one I replaced isn't 100% effective due to getting squished/distorted. It also could be preventing proper alligment of the coil contacts I suppose. I've watched other coil issue vids but those coils didn't have plastic washers. But also the flywheels in those vids were plastic w/ magnets embedded. The flywheel on this machine is all metal. Also if I touch the flywheel casing/cover during the short time it runs or while pulling the started cord, I get a mild shock. I don't expect a real diagnosis. I know I'm going to have to figure it out on my own. Or not ;) This is just someething I've never run across but I know I can't be the only one.
Hmmm. I haven't run across this engine, but I assume, like you do the coil needs to be isolated from the engine. Something is amiss if you get a tingle when touching any metal. I'd be looking at an exploded parts diagram to see what should be where. I wish I could be more helpful. Thanks for watching!
Great video! But if scraping that much out of exhaust port maybe clean it out fully as that is clearly a problem that will multiply!?
Thanks. I appreciate you watching. Cheers!
Enjoyed your video. Wish it had been around years ago. What other solvents would you recommend for cleaning the part if you don’t have old gas. Unfortunately or fortunately mine is at the age that might just be time to get new but now I know what to look for or reason for leakages.
I also use kerosene. I think folks across the pond also call it paraffin. I appreciate you watching. Cheers!
Thanks! The only other thing I would ask is maybe in future video. Add what type of heads are on the bolts or tools needed. Had to change the pull on mine once and finding the right head was a pain. Fortunately was at local maintenance shop and they were able to find it.
@@benj4131 Actually if you watch most any of my other videos, I always do, but I edited that out. That should be either a T25 or aT27. In this video I used a Torx T-handle that the numbers had rubbed off, I was unsure, and edited the size out. Subsequently I purchased some long reach 1/4 quick connect Torx bits, and promptly painted the T27 with orange nail polish before I used them (Stihl uses T27 on everything). I got another SRM225, and used the T25 (no orange paint) in another video. Someone called me out on that. I don’t have either machine to double check. Thanks for your comments. Cheers!
Interesting video. I'm not familiar with that type of pressure check. Why would the engine RPM's change if there is a leak?
The aerosolized fuel, in the form of carb spray getting into the fuel/air mix via the leak.
Did you check the rubber gasket coming out of the fuel tank? Or fuel lines to carb?
Only in as much in my poor-man's leak/pressure test.
An oily muffler like that one is a perfect candidate for the barbecue cook out method of cleaning. I saw this on the web somewhere and have done it on three or four 2-stroke mufflers. Just lay the muffler directly on top of an outdoor propane burner for about 3 minutes and flames will start coming out of it. A couple more minutes and the flames will die out. Then take it off with tongs and let it cool off. Finally, blow it out with compressed air. Beware it may make quite a cloud of white ash. Then it’s done. Clean as a whistle! I haven’t had any problems with solder joints melting, which was my apprehension at first. Also, I did not include the gaskets in this process.
I agree, that's a great method. I actually have done that with antique scooter silencers. Too big for a burner, it goes head first into a campfire. I imagine it lets off some pretty caustic vapors, but it cleans them very well. Takes a long while with all the internal baffles. Easy work on a trimmer howeve, maybe only one baffle? I appreciate you watching. Cheers!
@@TheLawnmowerLady Love your videos; keep it up!
Could the oil build up be from lack of high rpm running, constantly running it slow?
Exactly! I also think the other shop just replaced the spark arrester screen without cleaning up any other build up of blow-by. Thanks for watching!
