how to clean a cylinder
thanks for watching

I really appreciate how you often state..."if you can't get parts or don't have the funds"....
Thank you for being real!
👍💪
Too many people, and mechanics worry too much about compression. Sometimes all it is a dirty ring groove. If it pulls gas, then try it. Keep them out of the landfills. Great video. Take care.
Great video Tinman. I really appreciate you sharing your knowledge. I work on all of my stuff as much as I can. My tractor, my mower and my car.
Great video, always showing what your doing, why and how.
Thanks for the video. Gives me great confidence in honing out my 066 cylinder. Making me tempted to attempt my own porting job.
Thanks for sharing your knowledge everyone does things a different way and I always enjoy learning more.
I've saved a few cylinders over the years. I like to try and keep the OEM parts as much as possible. Did exactly what you did in this video on old homelites, echoes, pioneers and husqvarna. Nothing wrong with it. They are all still running to this day. TC Mahalo Tinman 🤙🤙🤙
Thanks
You seem to gravitate to the Caber rings. There is a site out of Virginia that sells popup pistons. They do not recommend the caber rings, and if memory serves they don't even sell them. They sell "grey ductile iron" my objective to fix this saw and it be reliable, not necessarily a souped up saw. So my question is, why caber over any other manufacture or grey ductile iron, what ever that is. Thanks Ken
Can you re-use the rings?
That was very instructive. Thanx a bunch Bud.
Did you see the clean-up Morgan @ Wild West Garage did talk about not throwing away your cylinder. I think you and Buckin have influenced him in a good way. Keep up the good work.
Thanks for passing along you knowledge
It’d be awesome if you did a 365 to 372 conversion video. Love all the content keep it up Tinman!!
Thanks for all you do. Helped me tons. God bless.
You're welcome
Thanks ! I just cleaned some mild transfer from a NLA cylinder for a PP365 just like you did here. It will live again.
I just did this with a piece of worn out 80 grit 😬
I've had success on my limited examples starting with alum oxide plumbers roll. It wears out quick so it cuts fast then slows down as you get closer to the chrome. I'll do a "spot" then pull a new piece and pick another one.
I think the abrasive material is the bigger one. Needs to be softer than the chrome but just hard enough to move aluminium. Got a roached husky 51 cyl i'm about to try in a few days. My dad bought it for my 51 boneyard knowing it was blown.. its in good shape. Going to surprise him and try to send it back running and minty looking. Only a couple little scores but a lot of transfer.
Hey, it worked!
Awesome video as always tinman! Cheers from the east koots!!
Great video, I’m cleaning up a cylinder on a old 009 top handle that I’m rebuilding ❤
Good video. Ive saved piles of oem cylinders the same way.
I love that you did the same thing with that crazy bright LED four paddle light in my little work light socket!!! They are just awesome for getting the additional light onto a project!!!
I've got those all over my shop. They are awesome eh??
@@tinmanssaws I love that insane amount of light available and that you can shoot it around at different angles and it’s a good light color… it’s a cold light but not super blue…. And they don’t draw back what a single 60 watt bulb would be using in power…so they don’t run your power bills up and they run cool so they aren’t catching stuff around them on fire… I’m just a huge fan of the LED’s… I just found a couple of new LED headlight replacement bulbs for $25 bucks for the set so the old 04 250 is going to be throwing triple the amount of light down the road so I’ll actually be able to see way better at night!!! I’m extremely excited to get them swapped into her!!!! You should maybe check them out if you haven’t already… new vehicle huge amount of light from our old trucks!!! And for $25 bucks it’s definitely worth the upgrade!!! 👍😁
i have cleaned up a disaster cylinder using a small brake cylinder hone with mild and fine stones. Lots of real light oil. Stihl BR350 blower, got new piston, rings and bearing and runs great
you do great man, thanks for the info ! appreciate it
Sound advice, I've just saved a ms241c that had worn the bottom ring locating pin which had resulted in a deep gouge from the top transfer to the top of the bore. Sanded the area with 240 grit then a thorough cleaning with rubbing alcohol finally finishing with jb weld extreme temperature paste in the gouge. Smooth off with 320 grit and she's running fine
I have cleaned up cylinders before, but watching your video has convinced me that I could have been even more aggressive at cleaning up the scoring. I have a couple of OEM 2100 cylinders that I was thinking of tossing, but I am going to give your method a try. I have never used the hone on a chainsaw cylinder, and have a stone type hone rather than a ball hone. I will give that a try on the most damaged cylinder to see how it works.
I've seen a video of russian who cleanded schorched places (only) with hydrochloric acid. it melted aluminum from piston and left quiet cool nicalis plating.
EDIT: of course, this method is only for nicasil cylinders
Love me some scotch brite .!! Great work !!
been using small cylinder and brake cylinder hones with fairly good success! Take er' easy!!
I picked up a Husqvarna 61 300th anniversary model that has a scored piston that I removed the cylinder because the ring was stuck due to the aluminum smeared across it. After cleaning the piston and ring and making sure it was moving freely i was debating whether or not to just purchase a new top end? But the price of an OEM cylinder changed my mind and I come to see what you have to say about that cylinder being scored? And this video was exactly what I needed to know if I could clean it up or not? And your cylinder looks exactly like mine and you made it look usable again so I'm going for it! Thank you for the great information Big T man! 😉
Awesome content for sure
"Scotch Brite 600 and nothing less"; thanks for saying this and for the video.
Do you ever build Stihl saws? Would like to see you do a 660/661 build. Getting ready to try and bring one back to life myself that a local tree service blew up and was trashing. Cylinder and piston look rough and I will definitely be trying to clean the cylinder before replacing now!
A lil off topic but, I just started riding dirt bikes after 12years of not riding at all. I bought a 250 two stroke and was blown away at the power of the newer 2 stroke bikes. I was having difficulty gearing the bike properly for where I ride and the top end ended up going bad and the cylinder got a small score in it. I cleaned it up really good with some emry paper lightly honed it put a new piston / rings in it and now the bike is just a bit tamer and so much easier to ride. I really think it was the little scratch in the cylinder wall that knocked the power down a bit makeing the bottom end of the power curve a little more curvier
Those ball hones take lil to nothing out of the cylinders but rather just leave a nice scratch pattern for the ring. People knock them but i use them all the time on my builds. After one tank of fuel the hatch is almost gone from the ball hone where the ring runs in the bore. For really damaged cylinders that have a thick plating Ive even used a 3 stone hone and you would be shocked at the results. I like the squeeze on those transfers. Makes a big difference in responsiveness. Some people gut the transfers and then there saws are super lazy. I like my saws to respond if you just breath on the throttle. LOL
i seriously use 150-200 grid sandpaper (not a lot of force is needed) to clean off the transfer and when im happy i clean the sandpaper 'scratches' with scotch brite, to soften those.
works everytime for me.
And this is why I don’t buy things from people that ‘fix up’ stuff as a hobby.
You’re a stand up guy, many of them are not in my experience.
love this channel ..just wondering if you could come down to nova scotia tomorrow morning and fix up my 026 lol...thumbs up !!
Have done that on a couple dirt bike cylinders! I like to get as much as I can out of oem parts.
I've been watching a ton of your videos. In rebuilding a 246 and a 162se. Witch do you think would be the better one to do a little porting work on? Nothing I need a timing wheel for just cleaning up the factory ports a bit.
great stuff Tinman. the other day you were painting a case on a Stihl for a fella. I was wondering what type of paint it was and what brand it is? I have been touching up cases with paint on all the Huskies I rebuild, but I haven't found a paint that is tough enough to hold up to the abuse that saws take. Thanks for your time Tinman, and love your content. Keep up the positive stuff, to many negative people out there. Shelby Wright
I dont think that was me? I've never painted cases.
I do that home under my sink with warm running water it’s a great lube and you can see exactly what you are getting… nice and slow and just a couple of strokes and you’re done!!!
HI TINMAN I seen a new chain the other day I didn't even know they made I haven't tried it yet a carbide full chisel chain I would like 2 see a 80cc or 100cc chainsaw pull that chain and see how fast it cuts OMG 1 18 2O23
I did this with my 550xp today. Repairman said it was junk. I went thru the coating just below the exhaust maybe 1/16 inch. Everything else cleaned up. I put it back together and ran fine.
I've saved many cyilnders and even some pistons in the past and they are still cutting today.
I really appreciate the videos you are putting up. I just replaced my cylinder and piston in my MS 290 from your recommendations of Wolf Creek Saws. And yes, Ryan was a big help. My question is, the old cylinder and piston really look good, no scaring at all. I just had low compression, around 80 to 90 PSI. Could I have through a hone to the cylinder and put new rings on it and be good to go? If so, which rings would you suggests for a stihl OEM cylinder and piston? Thanks
Ken
Often a new piston and ring is all you need. I like caber rings
Great video, do you have any basis porting saw videos, I mean a very basic, not aggressive port job. Just basic grinding and no lathe work. Please send link from you or anyone you trust. Thank you. What is your favorite oil?
I was worried for a minute about taking off the plating on my 044 when I saved it, but then I thought what’s the difference if I can’t get the transfer off the walls it’s no good anyways
Tinman, I had considered cleaning up my Stihl 075 cylinder with a Rotary tool and scotchbrite pads and then I watched this video to give it a shot your way and then will try to shine it up nicely with the scotchbrite. However, my piston has way worse looking scuffs than the cylinder did. I am guessing that with a new piston, rings and wrist pin and bearing, the top end should tighten up nicely and put the old gal back in service.
Oh yeah, and I meant to post how my 111 CC cylinder is so deep that my fingers are just a wee bit short to sand as far into the top as I would like. But I squeeze em in there pretty far. I almost thought of putting some Scotch Super 77 adhesive on some sandpaper and onto my fingers to hold the paper so it will stay on my fingers in there.
Will this work on newer saws? I have a 562 XP(2021) that got some less than perfectly oiled gas and the dealer said that(without getting into it) I can't do this because the chrome lining is too thin. But I heard you say that there is that same issue with these. I think I'll try your method! Thanks!
I have pulled saws apart that run fine and had scores that were filled with carbon, I left the carbon there fitted a new piston and ring and it ran fine.
I’m the same way with removing aluminum transfer, at least on the only cylinder that I’ve ever got hold of that had some.
Great post. How about small pitting from an engine that broke an exhaust valve and caused vary small pits in the cylinder. About 1 - 2mm in size. They don't run the length of the cylinder. Just small pits. I am trying to avoid buying a new cylinder.
Had a brief though… “Hey!… this cylinder doesn’t look as bad as I expected!… maybe I can clean it up… nope, waist of time...”
But, now I’ve watched this video and, found that these cylinders are unobtainium on the ole’ interweb, I think I’ll give’r a try!
Hi Tinman I would like to know what would be a good pistion for a 570 xp I am getting top head blown,no better after april /22 /23 thank you for your help.USA Halifax Mass. Steve O
I got a couple large cotter pins and I spread them and I slide in an old puddy knife in and hammer them flat so I can slip a strip of sandpaper through and chuck it in the Foredom!!! Make my own little flapper rig!!! Different grits and it’ll come right off… the ones a little wider for the strip of scotch brite … same one that’s used for the exhaust polish with the WD40 polish trick!
nice
I use a mandrel and start with 180 grit and go to 1000 grit with the mandrel and a drill as I can't justify buying the hones. Got a husky 55 I did this with about 15 years ago that I ported and it's my main go to saw I have 50 bucks in the saw total and it's still screaming. It's probably seen over 200 gallons of gas since I rebuilt and ported it.
Hey Tinman, if the bore is salvageable but the there are carbon deposits on the roof of the combustion chamber what’s the advice there?
Thanks, Paul
What if i have big scoring under the intake port and fine over the intake ? Its on a Husqvarna 42 spesial .
NICE VIDEO VERY INTERESTING CAN I ASK YOU IS IT NICASIL YOYR CYLINDER????
So I want to port my spair 046 what are some good timing numbers stock head. I watched all your porting videos and have a good idea of some numbers but I want to git closer and not go over.
my piston is scored i dont think its to bad wonder if i should re use it
If when cleaning a cylinder and some transfer material fills scratches in the cylinder, wouldn't that help compression? This is assuming that it has been sanded until you can"t feel a bump?
what kind of elbow grease you using these days?
I've ran some a hell of alot worse than that and they ran good to great.
It would be great to see an over the shoulder episode of you doing the intake and exhaust. Narrative optional, editing also. Rough realtime as it is. Kiss your kid for me and Momma for you!
👍👍👍
Hey good to see ya tinnman I have some stuff I would like to send you.
I use a little brick acid if its got aluminum transfer Tj
are stihl or husqvarna chainsaws easier to repair
Tinman i got a question for ya. When you grind those lowers out to dang near the max are you still gonna see all the performance incresse with leaving the intake and exhaust untouched?
I would add intake timing as the case volume has increased alot
@@tinmanssaws and the exhaust should be good enough as it is?
@@jeremythomas9134 well that depends on the saw, exhaust timing and transfer blowdown.
@@tinmanssaws im gonna hafta bite the bullet and buy a wheel. I only been saying that for a year or better...im kinda stubborn.
Alright thanks man. Always like your videos btw. Good stuff!
Just purchased an MS460 from ebay, that apparently "runs great"....Nope, piston is burned up! LOL.....Cylinder is good, And fuel line was broken in half, so I couldn't even start it(good thing)......but this is why you ALWAYS rip the muffler off and check the Cylinder before starting a saw......and trust no one's word about running condition. I'm going to get him to refund me the price for the piston...I don't feel like sending the saw back, since I already started rebuilding it.
Do you prefer ball hones or stone? What sizes would you recommend? I think you already answered my question. Lol.
Ball hones are what you should use on these types of cylinders. They need to be ordered to each size of bore.
Miuriatic acid for the win!
I knew nothing about two stroke engines two months ago but had to know why someone would throw put a two year old Echo backpack blower. Long story short the rings were trapped by piston material from what felt like a cylinder wall defect. I bought a replacement piston but didn't use it as I wanted to see if my cheapskate fix involving a file, sandpaper and the kindness of people like you sharing with idiots like me would do first. Starts on the first pull and so far I've put about 12 hours on it. Now I'm on the Pro Mac10-10 I brought home that smells like 1987.
A lot of times you'll see these kind of spots on the four mix Stihl FS 91r weed eaters like I just rebuilt on my channel but I'm not saying to go watch it unless you want to but it's usually from plastic wearing out from not enough oil in the gas and you get plastic on your metal surfaces inside the engine internally where it should not be and I learned you can clean up a lot of stuff but you can't clean up something that is pitted like the lifter followers
Where do you git a 90 foredum head at
Hey, Tinman, Which abrasive are your ball hones?
320 grit. It's silica carbide I think?? They are brush reaserch brand. They list specific hones for different types of materials.
Thanks! I was checking them out and noticed several different types.
What do you wash the cylinder with..... thanks
Soap and water generally
I can fix anything , just throw money at it. 👍🇨🇦
Hey tinman, where can I get hex keys like yours? Good day!
I think mine are from amazon
You ever use muriatic acid?
I've used acid and haven't had good results, I use this way and have save many cylinders.
also, I'm leary of muriatic acid..if there is the tiniest pinhole or scratch through the plating, the acid can get under the plating and pit the cylinder badly..if I do use acid, I use a q-tip and use it very sparingly, and rinse it off very quickly.
I've had very poor results with acid so I don't use it for that reason
This method has served me well. I have one saw with pinholes in the plating, it is pretty much a parts saw. But I have had great luck with acid.
Muriatic acid is the standard in the powersports world. It's always my go to. If there is a pinhole or scratch the acid can get through, that's a place the plating can lift and it's borderline junk anyway.
@@82f100swb - does the plating lift immediately, or after you run it?
@@wrstew1272 Sometimes it will go for years, sometimes it comes apart on the first run, sure tends to make a mess when it does. My own stuff, I will risk it and deal with it when it fails; stuff for someone else, if it's not right it doesn't leave the shop.

ok.. specifically... Western ON? MB? SK?
Btw, how much of this cylinder philosophy would also apply to concrete saws?
Come on Bud , really! you did that all wrong ,, chump! .. I m outta here . lolololol aahahahahahaa .. love you Buddy
Comment from me
Never get it round ,if you do way to much side clearance.
I don't trust using power tools doing things like that, hard to put back what you didn't mean to remove !
Your finger nail will feel what a dial indicator will hardly mesure.
We call it digitizing
You never......,
When ?and why? did they stop making thin piston rings? Seams like we are going backwards in the engineering sectors. Like engineers thinking crankshaft keyways are not needed. Just stupid derpppppp derpitty derpderp.
The rings have changed over the years mainly because of emissions standards.
aww thanks@@tinmanssaws
It’d be awesome if you did a 365 to 372 conversion video. Love all the content keep it up Tinman!!
