Thanks Don !! A clear, concise, and informative video. I'm so used to "how to " videos where the person rambles on, bobbles the camera, and shows the removal of each and every one of the 36 screws in real time instead of just saying " remove the cover". Job well done.
Well I checked everything out as you suggested, that was all good thank you for giving me the help. My pressure washer is now working great
It was taking about 20-25 pulls to get it started. Now after following your suggestions it has started on the first pull every start up.
Thank you for sharing your knowledge with us all. I myself appreciate your help.
Hi Don, You saved my bacon again, I was pulling my hair out with an Echo strimmer trying to get it to run right by just adjusting the carb. Saw your video (above) and now alls well with the world. Many thanks from the UK.
Great tip,not a lot of people even think of checking the exhaust port on there 2 cycle equipment
And it's so easy to check. Thx for sharing, have a great weekend Don.
thanks
Great video Don. Have never done this on our chain saw or our 2 cycle leaf blower. Thanks for showing us how.
Wow, I never cleaned the carbon from the exhaust on my stihl 026 and used it professionally logging for ten years and the piston looks great with absolutely no score lines or anything. It probably ran for a few thousand hours with no troubles, now I'm putting in a big bore 44.7mm kit and rebuilding the carb as I'm bored and it sat for 17 years as I joined the military and stopped logging.
Good instructions. Thanks so much.
Your videos make going to work on Fridays tough. Always want to get home and start tearing things apart in the garage! Thanks for all you do.
lol, you'll have something to dream about all day
@@donyboy73 oil mix 1:33 ok ? Ls+
Your videos are always clear and well explained.
Glad you like them!
Great instruction as usual Don, thanks!
Great tips. Thanks danyboy.
I was 1/2 expecting a stage 2 port and polish from you donyboy! Thanks for sharing these videos btw ;)
yes I know lol!
Thanks Dony, appreciate this one! I'm getting on this one right away.
Thanks for the tips mate, gd advise as always
I like the title to channel and I like the simple clear instructions keep up the good work
Thanks Donnie good job as usual.
Thanks for the information I haven't check the exhaust port on any of my machines now I'm going to
Thanks forthe video. Just finished cleaning carbon from my 2004 Husky rancher exhaust port for the first time. I've always run 50:1 mix. It wasn't too bad but it is clean as new now. Did a friends 80s era ProMac 10 that was WAY plugged upto where it just wouldn't rev. I think he was running 16:1 mix lol. Crazy.
Great video Donny! Hope Spring has sprung out your way. No sign of it around here :( Have a good weekend.
Great video very informative
Good tip Dony.
I'll definitely check this on annual equipment checkup.
Thanks.
have a good weekend
thanks, you too.
Hi thanks for sharing this information
Great video !
Great! Many thanks.
Great video, thank you.
Every Video i watch I always learn something. Thank you from a fellow Ontario Canadian. I visit Muskoka every year maybe I will find your Shop. Would like to meet you.
Great information thanks
Good tips as always. Thanks and stay sharp Mon Ami
merci
I am not a professional small engine guy but I do fix a few. Last year I got a weed whacker in and it was scored just like you showed. Very good video Don. I am now renewing a 1969 skil 1629 chain saw. It is a beast. You might remember a comment about numb hands and loose teeth from vibration.. Well that is the one.
Bruce
hopefully it will run good for you
Good video dony
excellent video
Good idea!
I like to use a small plastic scraper and its not necessary but I usually take off the chain brake as well for easier access!
Sea foam in the aersol can is amazing for loosening carbon deposits. Just spray the area, let it sit for a few hours and most will wipe off with a rag. Take a flathead screwdriver to get the stubborn chunks
Hi, thanks for the video. you save my machine. thanks. What's the reason for oil leaking (brown color thick oil) from the 2 Cycle Engine Exhaust Port
Great stuff
How often should I have my heaviest used tools be cleaned if they are being practically almost as much as commercially used ones probably are. Can the fuel octane effect carbon build up or cause other issues. As always thanks for your informative videos. Before U-tube all I could do myself without causing more damage was pretty hopeless. Thanks for your videos. I have ended up recommended them to a few friends also who were real happy with the results to.
I've found that good modern motorcycle pre mix thats designed for power valves runs pretty clean.
Small dremel tool wire brush works great, used on my Merc xr6
Good oil good gas and proper maintenance ✔️
More great tips that I need to write down. Thanks Don!!!!
nice, I'll have to clean out my engines some time, at least the carbs.
Thank you very much. I've been using red armor at 32:1 for milling lumber on a ms660. I realize it leans out the mix when I do this, but I've tuned the saw for that. Do you recommend 40:1 or even 50:1 for milling then? It smokes a little on start up but then I have no smoke whatsoever for the rest of the day. 2 pulls to start.
Hi Don. Please can you tell me which aditiv can I use for engine carbon cleaning? I saw sea foam and many others, which is your recommendation? Thanks
do you get carbon build up near the piston?
and if you do how do you clean the stuff close to it without scratching it.
my go-ped had a slight bog so i cleaned out the carbon like you did and i made 100% sure that no bits of crap were still in there and i put everything back together and it was worse, so i let the motor cool for 15 mins then went for another ride and it was fine?
When am cleaning the exhaust port i usually spray a little carb cleaner on it and let it sit for a while and then gently scrape it off. This way the exhaust port don't get scratch, carb cleaner i used is called Bars Carburetor Cleaner. works real good.
I have a question for you: I have a Karcher 2400 HH pressure washer with 5 hp Gc160 motor. I adjusted the valves on it & checked the spark plug. I am trying to get it to start with 3-4 pulls. Any ideas as to why it takes about 20 pulls to start?? Thank you for your time in advance,
hello dony i have some older husqvarna and some newer should i used 40.1 or 50.1 what you think is the best mix thanks
Thanks!
I use a dremel with a strait brass wire brush to do this. Much less time consuming and gives it a smooth polish. Though I rarely have to do this because I mix my oil right and keep my equipment tuned correctly.
good tip
Good video
I have an older lawn boy ,Do I need a Gasket between my manifold &?some one else never installed one the muffler
What size heli coil would I need for this port as I have a broken bolt in mine .Have you ever had any success with heli coils
Does synthetic oil mix produce less carbon?? Great video as always.
Don will a plastic scraper work for that or is it too weak?
thank you
thanks for watching
Question for you is: can’t you use sea foam in your fuel to aide in the carbon cleaning? Enjoy your videos very much. You have helped me with almost all of my small engines. I appreciate you taking the time to do them.
yes you could but don't put in too much because it may harm carburetor seals and diaphragms
Thank you for that quick reply. Keep up the good videos.
The motorcycleMD did an interesting test soak of lots of different carb parts in all the common cleaners, sprays, dips, ultra-sonic, etc. It seemed the Seafoam was the mildest/ most forgiving of the chemicals on the seals and diaphragms of all of them ...berrymans being pretty harsh. For what it's worth!! Worth a watch. 😊 thanks Dony!
For our motorcycles and motored bikes, we made a habit of taking off the exhaust pipe, torque pipe, pitch pipe, (whatever), and chucking them entirely into a hot burning slash pile or out of control camp fire and just let the red/ yellow/white heat of the metal consume the unwanted dinosaur juice and at the right moment (your timing may vary), chuck them into a back eddy of the local creek, which, alone, could raise the most amazing pairs of goosebumps on our girl friends with it's intense lack of warmth. After the ceremonial beer, the last one done got thrown bodily into the crick to fetch them back to the fire where they were gently hotted up to prevent internal rusting. The exhausts, I mean. Pocket knives did for what else seemed to be in the way, but it was far from unusual to see a couple of half drunk dudes dead lifting a 501 Maico upside down to shake out any suspected strays. The neat thing was that no matter how bad a job you did, any effort was always counted as a success because every litttle bit made it run some better. Good video. Keep it up!
I hope you have less snow than me. This is the first time in over 20 years we have had over 5 feet of snow this year. We still have a foot and it also have been cold -20f with -45f wind This was the first time in about 4 years that I did not put my 46 inch snow blower on my garden tractor. I can not use either but my son can use the Ariens 32 13hp snowblower. After the first snow I could no longer get to the tractor or the snow blower for it.
Had a commercial weed eater seize up on me. Sprayed some penetrating oil in spark plug hole and tapped the piston with a wooden dowel to break it loose. It ran but over heated shortly after. When I finally tore it down I discovered so much carbon had built up on the inside lip of the port and hardened that it was acting like a set screw on the piston not letting it move. The piston was ruined, looked like an animal had clawed a big chunk out of it. Cost me $80 after I bought new piston, rings, and cylinder (jug). I could have reused the cylinder but decided to get a new one since It was pretty old. I now check the port regularly and care more about my oil/gas ratio being more spot on. I use to think more is better than not enough, which is true but not all the time. Try to get it as close as you can and only go over on the oil if you have no way of measuring it.
Does the ultrasonic cleaner work on the spark arrester?
Great video. I have heard people using a scrapper made of wood to avoid scratching the piston. How do you clean the carbon off the top of the piston without dissembly?
i take it apart
My dad has a shindawa chainsaw with a 16" bar on it. I took off the cover where the carburetor is. Is it normal for there to be a lot of build up of saw dust in the that little compartment where the carburetor is?
I will definitely have to do that. Might even do it today. Do you have any suggestions how to cover up the hole for the carburetor so I don't get any dust in it? Thanks for the reply. I really should get into the habit of doing what you do with your saws.
Love2boat92 did u not c donyboy moving the cylinder so no carbon wouldnt get inside do that then hiiver out sawdust.
I make a rule to clean up my saw after every use. Today I noticed black coating on the bar and casing on the same side as the exhaust port. Could that mean too much oil in the mix. I use 40:1. But this saw says to use 50:1. Could that really make that difference.
what happened when I ordered the piston and piston for the Jonsered trimmer and the old piston regulator had the intake near the intake opening and if you put the new one so that the break is on the same side, the arrow of the piston will be on the side of the intake opening..that trimmer was bought new for us..ali express the piston and piston are now new
Question for you? I have a Karcher 2400 HH pressure washer with a 5 hp Gc160. I have to pull about 20 times before it will start sometimes more. I adjusted the valves & checked the plug, all is good. Anything you can recommend for me to do to try and get it to run after 3-5 pulls?
I really trust your videos and value your opinion. I’ve watched many videos on utube, you sir are by far the best one out there. Keep up the good work & thank you in advance for your time.
you may need to clean or replace the carburetor. also check choke butterfly to make sure it closes when choke on
Got it thank you for your reply. I will look up your carb rebuild video for sure. Thank you very much.
Also, on the pressure washer, make sure the wand trigger is squeezed so you are not fighting the pump trying to pressurize the water. Then the engine will spin easier.
I have no Drexel or sea foam can I use wd,40 and or mixed gas ?
I have a Stihl gb55 blower and a Stihl f38 strimmer but I can't find any filters on my exhausts. I took the exhaust off and cant find out. Any ideas
Hey don i'm working on a yamaha 570cc snowmobile engine for a project it needs a top end rebuild and the wiring harness is still good should i fix it or part it and i am doing the rebuild myself
might be worth it if you do the work yourself
is it better to use sand paper or steel wool when cleaning the exhaust port of a 2 stroke engine?
Josh Chelvolski wire toothbrush
I usually us a wire wheel on a drill to clean the exhaust port and then I blow it out with the air compressor with the piston near T.D.C Usually looks nicer and I know 100% the carbon buildup is gone.
Generally, I only.use a metal object like a screwdriver only as a last resort.
You can get bamboo scrapers that are about 0.5mm with a 45 degree angle cut on them, I use these to scrape the ports, if you have a slight slip or do scrape the piston, you won't score it.
If it's stubborn carbon, spray brake cleaner, let it sit for 5 mins and spray again, then scrape.
Can get it almost metal polished-clean.
Before steering kit, put a drop of oil in the port and hand turn it, just to re-lubricate everything before it goes under load running....
Dony, My Saw is like the one in this Vid.........How do I remove the Muffler ? The Cover seems to not detach. It is blocking the removal of the Bolts at the Cylinder. Thanks
remove the top cover
Could I use a wire brush?
Champ!
I know this is a old video but hopefully my comment help someone.
I like to use a Dremel with a Little wire wheel and then polish it.
also need to have your carb tuned right too.
at 1:20 I can see brown residue on the piston directly underneath the piston ring.
What would be the cause of that?
I have seen this too on my chainsaw.
If the spark arristor is blocked, the combustion with swirl in the muffler and exhaust port as the piston continues to travel
Which way are you supposed to tip lawnmower,if you need to take blade off
my cord on my brush cutter was hard to pull so I pulled the recoil off and it looks perfectly fine, however if I remove spark plug the cord is easier to pull, so to check for exhaust issues, I ran a compression test and the compression was decently high at 150 and I notice almost little to no air coming out exhaust pipe, so I pulled exhaust off, and I noticed that the port is full of carbon but looks similar to your video, as I started to clean it the cord got a bit easier to pull. to fix this do I continue cleaning it more? How do I get the crevice or corner thats touching the piston safely?
Pour a oil/gas mixture into the port and let it sit. That will soften up the carbon so you can wipe it away with a rag wrapped in a screwdriver or blow it out with compressed air.
I remove the spark filter it's always cloged. do you use a solvent to remove the rest of the carbon?reg gas or something.
i use a propane torch to burn off the carbon from the spark arrester screen
I am sure you do not need to put the spark arrestor back in. It basically just quietens the machine down a couple Db's but also allows engine to breathe alot better as there is nothing there to restrict the flows
The spark arrestor does just that, arrest the spark before it leaves the muffler and starts a fire. (forest).
How did you pull over the engine to block the port?
Do the little scratches in the exhaust port from the screwdriver make a difference? Is there a tool that wouldn't cause them? (Brass brush maybe?)
they won't matter,you can use a small brass brush if you can fit it in there
rpavlik1 Owners manual recommend that you use only plastic or wood to do this procedure.
Can you show me how to change a pistón of 562 xp husqvarna?
B12 works great , just be careful digging around in port, you’ll damage piston wall
Wide open toggle folks
Dony I use stihl motomix in my stihl chainsaw and weed eater do I still need to check the exhaust port?
as a precaution i would still check it
@@donyboy73 I will and thank you so much for taking time out of your day to answer my question. Stay safe and thank you for doing your videos you have taught me so much.
Thoughts on made home made kit .to run genators on is long term damage to it
How many hours or years does the carbon build up like this saw?
all depends on factors such as oil fuel mix, and the user
could you burn it out with a propane torch?
Fill the exhaust port with Seafoam and let it sit about an hour. Then the carbon will wipe out with a rag. You're welcome :)
Thanks. That was my question. SEA FOAM ???? How about sea foam in gas every SIXTH tank to get carbon out of cylinder and piston face ?????
@@boedayious4993 In my opinion that is a great idea. I do that often.
Didn’t read this comment thread but that’s exactly what I did. Need to put some in my edger/trimmer
My spark arestor is not removable from my muffler. It’s a Poulan pro leaf blower. Can I just spray brake cleaner or sea foam on the screen of the spark arestor (it will end up in the muffler too) and let it dry and see what happens? Thank you to anyone that can help with this question.
How long does it take for that much carbon to build up and same for the spark screen
usually years, but sooner if there is too much oil in fuel
Ok so I think im ok for now the saw is only 1-2 years old now and it has been running fine. I might take a look in the future
I was given an older Stihl FS44 string trimmer. It needed a primer bulb, which I replaced. The trimmer starts and runs, but there are two probles: the engine runs at full speed all the time even when I am not holding the trigger (the throttle is stuck open) and when I turn the switch OFF the engine stays running. If I put the choke back on it dies eventually, but I would like to make the machine work 100%. Any ideas on what is wrong? Thanks
Wayne Manion tune the carb down for the speed prop
How about a light scrub with a fine scrub pad or SOS pad
Ever hear of this? Replaced piston ring on 25cc WeedEater Trimmer. Compression at 130 now. Engine performs well but.....only if I remove the muffler completely. New muffler makes no difference. Idles only. Take off muffler, runs great. Tried old muffler, same results. Replaced cylinder head with new one, no difference. ?????
I have a 1996 poulan 2175 and the piston and jug isnt scored at all it just broke the piston ring so i was wondering how could i get piston off rod and change both ring and piston. Wanting as a back up saw again
Kylee Bates take the cyilinder off have shop born.out the cylinder and get a new head and piston n ring ur fine
You cant bore small 2 stroke cylinders it has a nickle coating on the cyinder walls
do you use anything to measure the oil to put in the gas?
I use 100ml cans
Okay thank you.
Great Video. You know your sh*t
