Watching your videos is like going to school remotely! This is the wave of the future! Thank you for teaching us and sharing all your knowledge! Thanks Tinman for another great class!❤️
"So long and thanks for all the beer, eh?" Happy New Year all, gotta be better than the last one. "Cooofffffeeee!!!!!!" Running hot. Steves Small Engine Saloon had something about that. Basically, cold saw, start it and immediately push hard into a cut. Worst thing you can do to a saw. Cold saw, start it, let it warm up, ease into the cut. Basically same thing with any engine: let it warm up before you redline. Tinman, thanks for sharing, here's hoping the air flows easily in the new year.
Boy some guy have all the fun playing in the snow. I been lucky enough not too have get our loader out for clean up. At lease you got yourself a cab too work in.
Great job Tinman. Keep up the great work. I do tend to use coarse sandpaper after I get rid of the high spots. Not enough to take material off though. I’d like to think that adding some deeper grooves holds the oil a little better on the piston skirts. Looking forward to see how that echo turns out.
Awsome video as always! Had to break away today and go cut some firewood to take my mind off the garbage going on! Watching this channel and others really helps to get my mind off of things! Saw was cs680 Echo got bout 3 tanks through it! It runs really smooth, however if any of you guys pick a new one up they come tuned very lean at least mine was! Think will be pretty strong saw after few more tanks of fuel and a lil finessing of the muffler!
Lucky. Here in Europe we keep getting wind currents from middle-east/africa, so not even freezing cold outside, just damp af :( Where are the Siberian currents god damn it, feels like we had a 4 month long autumn so far lol.
Thanks! If I do the honing and sandpapering. Is it going to be gap between the piston and the cylinder? What is the minimum PSI for a trimmer / chain-saw to work? My cylinder in the trimmer had 45 PSI first. I changed the piston-ring and that did not much. Was up to about 55-60 something. After that I took 2000 grit on the cylinder and made it up to 75 PSI. That is where I am right now. I changed to 600 grit as I saw you did it.
A guy I know said he has a stihl ms391 and it locked up. I'm excited to tear it down if needed and see if this is what it needs. Since pistons and cylinders are hard to find at the moment. Thank you for the info 🙏
Not finding a piston is my problem. I bought my dad a Pioneer 1200A for Christmas back around 1975. The piston is a bit scuffed. I found a new cylinder, but the piston and rings seem to be unobtainable. I'd love to get it going in his memory.
widen the exaust port a little drill a hole in that mcculloch carb deflector above the intake throat and make u a air filter out of that red and yellow unifilter material and they will come alive!!! try it
Looking great Tinman! Anyone can build an engine with new parts, when you salvage and build something great then you've done something! Keep up the awesome work 👍👍💪💪😁😎!
Tinmaaaaan, like the fact that you're using the piston that came with the saw. At least you can run it as is and see how it pulls. Curious to know if you've ported the Mac? SLANT'E
If one sands the piston and cylinder too much will the likely results be piston slap and/or less compression than I had before I tore it down? I've just finished sanding the scoring on my Stihl 193t piston and cylinder because it had 90psi (have not yet installed and I'm awaiting a factory ring). I want to try and save the factory piston/cyl to reuse until I lose compression again and I also want to see what the results will be by attempting to clean and reuse. I figure if I use 40:1 mix it may give it a little more life.

"They're older fellers". Hey I resemble that remark. LOL 🤣
You know you're doing ok when the "older fellers" are watching your channel. 💪
Finger nail is a great tool for finding irregularities. Especially when your in your mid 50's and eyes aren't as good as they once we're. Thanks
The chainsaw community keeps getting better great to see so much intrest in chainsaws old and new ,can't wait to see it in wood thanks Tinman.
THANK-YOU SO MUCH MR. TINMAN, WE LOVE YOUR WHOLESOMENESS, LIFE IS GOOD, COFFEES READY !!
More good info for us that like to do junkyard builds! Thanks for sharing buddy!👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🙏🙏🙏🙏

Great info again, as always Tinman keep up the amazing work.

Sharp edges not only cause scratches and or transfer, they also create stress risers. They also can cause hot spots which to lead to detonation.
Thanks Tinman! Great tip! Keep all the awesome info coming.
Great information I cannot wait to see this saw turned up hot

Thanks for showing us how you do your work. Looks like I need to come to your place to take my sled for a rip there’s no snow in Brandon. Lol
What a great evening! -25 degrees celcius outside, a gigant cup of coffee and Tinman on the iPad! Is there anything else you can wish for? 👍

I know... I do live in Sweden... 🇸🇪
I've buffed up some pistons on some stuff before. love the work you do buddy. I got half my parts bought up Christmas slowed me down lol.
I like to keep a couple different size old pieces of piston ring to clean out the groves. Free tools😉🛠️
This was a great educational video!!!
Good information as always! Thanks buddy💪🪓
Awesome Tinman. Thank you buddy for the great tips on piston revival. Lovenit. 🌲❤🌲✊🪓
Thanks for being here Tazman
Hey buddy I see you are gonna go live tonight. My service at work is not so good so I might be lagging some but I will try to be there. 🌲❤🌲✊🪓
@@tinmanssaws Hello, you can use 1:33 ls + husqvarna in saws 372xp 357xp and scythe 545rx without damaging carbon deposits? is it better 1:40?
Great info there bud can't wait to see em runnin!
Hope you had a great holiday season!
hey Tinman! Happy new year!
THANKS FOR THE VIDEO TINMAN LOOKING FORWARD TO WATCHING THAT MAC GO THROUGH SOME WOOD SURE SHELL BE A GOOD RUNNER BE SAFE TINMAN

This is good info.
Deburring tool help on edges also then sand paper.
hi, a have clean up piston couple times on my dirtbike,it did work realy good
A guy might just be too cheap to a buy a new piston so cleaning up the old one will come in handy. Thanks for sharing Tinman
A guy I know said he has a stihl ms391 and it locked up. I'm excited to tear it down if needed and see if this is what it needs. Since pistons and cylinders are hard to find at the moment. Thank you for the info 🙏
How did it go ?
Hello tinman...looking forward to up coming installments...
Sup Nicky??
@@tinmanssaws hey tinman😎👍...just sitting here watching buckin ...were gone into another u know what here....

Try a homelite xl 12 or xl76, i think one of those will fit.
@@tinmanssaws Okay thanks. I will check them out.
Thanks Tinman! you inspired me to start my own Channel!
Thats awesome!! UA-cam is a great thing, I'm glad you made the descision.
I just bought three promac 610 McCullough chainsaws.
Congratulations on your buy I hope you enjoy them a lot 👍
widen the exaust port a little drill a hole in that mcculloch carb deflector above the intake throat and make u a air filter out of that red and yellow unifilter material and they will come alive!!! try it
Nice. I have one of those. I really like it.
Thanks, Kelly, for the performance tips.
Can’t wait to hear that Mac running .
THANKS FOR THE INFO
Thanks for being here oldtimer!!
Nice vid

Wow I’ve never been to the snow before
This is the way

if you have scorch marks would you be able to get rid of them by sockiing them in a degreaser???
Have you considered dressing the crown the same way one would lap a cpu heat sink ?
U got that right. Those skirts crack then ruin a good cylinder. Keep eyes on those important. Other wise run them till they crack.Lol.
Hello, you can use @ ls + husqvarna in saws 372xp 357xp and scythe 545rx without damaging carbon deposits? is it better @?
Carbon build-up is the biggest reason for failure!.....not "mixture issues" like everyone thinks!
i use my finger all the time
Can you titanium pistons
i think its needs a 6 speed and a pipe lol
Mcculloch 1-43 has no power ?? Rings?
Your finger nail will give you by far the most accuracy. Try it on a knife edge you'll be surprised at the definition it gives.
Will it hurt the saw to run it with scores on the piston
Yes, it will burn the cylinder Next.....
what are the exact specs on a turdsaw?.....acres site don`t say pretty sure i have a few though
They usually have a big ol “homelite” label on the side.
@@tylerlong1222 i know rite! gotta roll with what you like
Hey I’ve got an old mculloch chainsaw and it has low compression what would you do? I think it’s called a timber bear 20 inch bar 55.5 cc
Often you can ckean up the piston and install a new set of rimgs and you're good to go.
@@tinmanssaws thanks tin man big fan you and buckin billy ✊🏼🪓
How do you address the ring groves?
I clean then with a dental pick and/or sand paper. If the ring is stuck I usually toss the piston.
Hello
Good video, I just did this on my 272XP last week - check out my video if you get a chance, would love to know what you think!
