over the last year, in prepeartion for taking on my new interest in chainsaws and porting, i've bought approximately 15 saws, an ultrasonic cleaner, a compression tester, a mightyvac pressure/vacuum tester, a foredom flex shaft, a timing wheel, and a few other things. I haven't done my first port job yet, but I am taking in all of your training. i am extremely confident I will be able to make nice work saws after i finish all of your training. it all makes perfect sense. i love how you explain things. you truly are a great teacher. i originally intended to port 4-5 of the saws and leave the rest stock, but you said it is addictive to port saws. i can already see that coming!! thank you, sincerely
Good day all. A little trick I’ve learnt to fix those stripped holes in plastic. Is to place a piece of weed wacker string long ways into the hole then the fastener. I hope this helps someone🙂
Bless you for taking the time to educate and couch us. I am writing down the steps you are taking. Me and my son will be buying the necessary tools to start porting. First thing is a Timing Wheel. This educational video series is like going to Tinman University For Porting. You graduate when you have become Tinmanized!!!
i dont mean to be off topic but does someone know of a tool to log back into an Instagram account..? I was stupid lost the login password. I would appreciate any help you can offer me
@Abraham Mitchell thanks for your reply. I found the site thru google and I'm trying it out atm. Looks like it's gonna take a while so I will reply here later with my results.
Tinman, break the rest of that plastic off the T-handle and weld a piece of round stock to it. Works for me and saves me a trip. Love watchin your tutorial. Thank you for sharing with the community
People do know thy can pause and rewind youtube right? I've gone back and watched yours and Ironhorses porting videos again over the last couple of weeks just to get my head around some of the stuff I've missed. This is going to be a good series. Smitty's Chainsaws And Firewood is going to do a porting series on a Super XL if anyone is interested. Cheers Tinman.
YOU KNOW, THE "I WENT TOO FAST" CRITIQUE DIDN'T MAKE SENSE TO ME UNTIL YOU DID IT SLOWER, SO MANY LITTLE MOVES EXPLAINED-THEORY TO APP, GOOD CRITIQUE. THANKS, TIN MAN.
I didn't mean to be so coarse in my first comment on the 461. I apologize. I really need to know how to deck a saw & time it right. I port a bit of the transfers, exhaust from the piston out & intake to the piston. I've also got some prototype air cleaners for a 461 & just those adjustments have made it the hottest saw I've ever ran in 20 years of climbing & cutting trees. Once I learn this timing & decking stuff I'm gonna be unstoppable. Also did these things to my 372xp x-torq & its a banty rooster. I love every bit of this slow shit. I must be slow🤤 42 & still climbing... but I love it & chainsaws just as much as you do. Thank you.
Thank you for breaking it down Barney style! My brain housing group isn't as reliable as it used to be - head space and timing is a little off. Great content though, I really appreciate your attention to detail and the time you take to make these videos!
This is so good. Always start with the basics, just like you're doing, (timing wheel,etc), and take ones time, measure twice,three times, and cut once....
Thanks Hoss. I'm writing it down step by step so I can have it beside me on the bench. Deciding which saw to do is a problem. I have been given several saws lately.
Great intro. I started the cs-680 the same way. I got it running today as picked up. It was missing the clutch, so I will be shocked if I don’t find an oiler issue or maybe an air leak. It will take more investigation before I tear it down. The crank end was good, and there’s no play but I can’t believe it was abandoned just because of a $45 clutch.
Dude, you have another subscriber. I really like your knowledge. I started watching you yesterday. I’ve started searching for unwanted saws to tear apart and fix. Been a auto tech for 42 years. Fell in love with small engines in college. I now want to work on 2 strokes. Thanks
Time for me to buy a timing wheel. I put a dual port muffler on our stihl 461 and tuned it with the help of your tuning video. Definitely a difference! Thanks for your help man, this is great stuff!
Man, perfect timing... Night before I saw this I was doing the ring trick for the transfers, but was not sure I had it right. This helped quite a lot. I'm following this like crazy. THANKS!
This series was incredible. I'm not mechanically inclined to tackle these upgrades just yet. I've successfully rebuilt an older Stihl top end, but that timing wheel has me nervous
Yeah, this one was pretty intimidating. I know it's probably super simple to figure out when you do it a couple times, but I've watched it twice and still aren't fully understanding.
Tinman, fantastic video! I've purchased a few chainsaws and am excited to tear into them and see how each operation I perform reacts. Thanks Tinman, be safe.
Love this series, learning a lot, and believe it or not it's to rebuild my 365 special. Put a big bore kit in it, and blew it up 2 weeks later, so next build I want to port it
I grew up around this kind of stuff and even if you do everything perfect sometimes some saws will blow for no reason great video as usual brother I really enjoyed it👍👍
Thanks for your help and time to help me build better power saws! This is big an addiction as building pulling tractors. Keep up the awesome videos 👍👍💪💪😁!
Hey guys, how's everybody doing? Greetings from the mountains of East Tennessee. Listen, I have a cs4600 45cc saw that looks like a smaller version of this cs670. First off I love the design of this cylinder, especially for a saw designed in the '80s. But a ferrous metal ring is pressed into the intake port, which the rubber intake boot slips over. I have no doubt that the designers in Japan didn't press this metal ring into the cylinder head for shits and giggles. Although I do see evidence of enough overengineering to make the Germans blush I can't quite see the purpose of this ring. I was thinking it serves as a heatsink perhaps to lower emissions but I don't think they worried too much about such things back in the 80s. Does anyone have a clue as to why they did this? Love the channel and the enormous depository of valuable information it has become. I've been an A&P aircraft mechanic since 1990 for whatever that's worth.
I’ll admit I may of been 1 of those impatient ppl that couldn’t wait to port there saw lol!! 😬But luckily it all worked out😅 Great video though, more knowledge the better I always say! Thanx again Tinman!!
Hey Tinman. I use a drill chuck like yours and i found that using vacuum caps meant for cars helps hold the drill chuck tighter if you put one over the threads. It also helps insure you wont mess the threads up to. i forget the actual size sitting here but i all buy is the small assortment pack.
I just bought a 660 and a husky 550xp. They both seem great out of the box but id love to have them both ported. I just got them both 2 weeks ago and they dont have 2 hours on either of them yet. Id hate to ruin either of them but im wanting them to run like ones i see on TH-cam
I’ll be porting my poulan wild thing I just replaced carb and fuel lines on. If that goes well. I’ll port my clone 660. I cut big oak here in Florida and it would help speed up jobs. Thanks bud
All I need to port comes from Tinman! Now I need a cheap saw and have my cataracts done 😄 Tinman, maybe talk about what grinding tools you recommend for the Dremel?
Was there ever a truer statement than what Tinman said: “You’re gonna start porting and get addicted to it.” That is so true. Running a stock saw is so hard to do after you get bit by the porting bug.
I’m getting ready to rebuild my 026. What brand or brands to you suggest for long life also, do you know an approximate HP increase on the 44.7 mm combo over the factory 44mm. Thanks. Really enjoy your work.
Thanks Tinman! Sure would be nice to have a collet setup on the timing wheel. 3 jaw jacobs chuck is ~.003" run out on a good day. Do you find that a 3/8 chuck will handle most crank shafts? I learned to not use rosin core solder too. Puts a some junk in the cylinder. Waiting with bated breath for the next episode!
Hey Tim man if I delete the gasket off the cylinder head and check the squish will I’ll have to re adjust the carburetor in rich or lean ? Or should I just warm the Saw up and run it a few minutes and do a plug check ? Any help would be greatly appreciate it thanks buddy
Almost looks like you could put a husky 56mm 395 XP cylinder on that echo With some work . When I get a motor that's dirty like that I use purple cleaner with some dawn in a spray bottle and clean the heck out of it & then with the garden hose & spray it off with air & WD 40. I like your degree will set up.
Tinman, I believe I have a rival for how dirty your echo was. I am close by if your interested in seeing it just for laughs. I’m going to tinker with is see if I can make it work. First pull rope broke, haven’t hardly looked at it since.
Hey Tinman, question. Restoring an old Homelite 5-20. Wondering how to clean the cylinder and carbon off top of piston. Can I lite hone the cylinder without damaging it. Thx TM. Keep the vids coming.
Wd 40 and scotch brite cleans up the carbon...it's not fast, but it doesn't remove metal from the piston thus lowering compression. Lots of elbow grease.
tinman, does it matter when timing your transfers with a ring which way you turn the timing wheel when piston is at BDC? And in general, when finding the timing numbers, does it matter which way you turn the wheel?
I have watched the video twice and I can't figure out where you come up with the 122° number for the 20° difference. When you use the ring, you stop it at 122°. How do you know that's where to stop it?
Im lost as to how the exhaust is 102 both before and after the base gasket removal. That cylinder dropped 10-15 thou, but the degree of rotation didnt change? Why?
Hey brother I'm still waiting for you to put that video up when the kill switch didn't work and you got shocked you said if you find it you going to put it up there I want to hear you jumping swear a little bit I bet me ..lol...as always thanks for the videos thanks for your time I always enjoy watching you.. hey if you're looking for some good bearings and case pullers stop by and talk to Matt Olsen he does some good work and John Reilly him and I have been cutting Pistons down and doing some crazy things lately all right brother have a good night will see you in the shop probably Wednesday right Tuesday be good to no pressure..jk
Here’s a dumb question: doesn’t the flywheel key ensure that the timing of the saw is correct in the first place? Why else would there even be a key? I understand that this assumes that no other mods are done such as porting. But if all one is doing is a base gasket delete do we still need to catalogue timing? And what do these timing numbers even tell us? Shouldn’t TDC and BDC be 180 degrees apart?
hey tin man drill a hole in a sacrificial piston or cut the piston in a pie shape and stick a small camera in there to see your transfer on the inside weve done it and it works

Good day all. A little trick I’ve learnt to fix those stripped holes in plastic. Is to place a piece of weed wacker string long ways into the hole then the fastener. I hope this helps someone🙂
Also . To not strip them .....turn screw backwards until you feel it drop into the threads. Then turn forward . 👍
Thats what I do as well
I’ve used aluminum foil, but I bet trimmer line is better for plastic. It would certainly be easier.
Small section of an appropriate sized zip tie also works a charm….
Bless you for taking the time to educate and couch us.
I am writing down the steps you are taking. Me and my son will be buying the necessary tools to start porting. First thing is a Timing Wheel.
This educational video series is like going to Tinman University For Porting. You graduate when you have become Tinmanized!!!
getting couched has different meanings apparently
I prefer to be coached
Thank you for making this series Tinman! Really appreciate you taking the time to do this for us!

Tinman, break the rest of that plastic off the T-handle and weld a piece of round stock to it. Works for me and saves me a trip. Love watchin your tutorial. Thank you for sharing with the community
Right on. Thanks for that. I’ve got a set of those and I just know it’ll break one day. Especially if I use em in the cold weather
@@shapeshifter7753 I broke many in my day. Cheap and expensive. Weld round stock, will last forever. Glad to help

I just watched a bunch of your videos and although I do have chain saws, I’m more interested in my vintage 2 stroke dirtbikes. Great Job !!!
That cool, I have an 83 yz490 that will be on a channel project one day
@@tinmanssaws those 490s were monsters and I’ll be looking forward to that one!
@@hugieflhr03 yeah buddy I was super excited when I found it, legendary bike they are!!
Bondus “T” handle Allen SAE, Metric and torx are the best. They have rubber coated all steel handles
What set would you use most on chainsaws?

Thanks for your time man. Big steps with these videos.
Always like the knowledge. Your mistakes keep from finding them out for myself although I'm sure I'll push to far sooner than later 💯
Once again Mr. Tin man. You hit the mark. Great great teaching video. Keep up the great instruction. Thank you
Thank you for taking the time to explain and for the useful information
I am learning so much through this. Thank you so much for making this.
You're welcome, thanks for watching!!

That method of mounting the degree wheel is very clever
THIS IS REALLY GOOD INFO, SHOULD HELP A LOT OF PEOPLE
Great Video Tinman, loaded with great how to information !!
Looking forward to every video in this series !!
Thank you ! 😊
have ever run a ported poulan 7700 and 8500 I heard of both I haven't seen none
Very informative. You are a good teacher Tinman.

Great breakdown Tinman. Really appreciate you taking the time this will help alot of people, myself included thank you
👍 nice and easy to follow. I think your going at the right speed
Cylinder looks brand new man
I’ll admit I may of been 1 of those impatient ppl that couldn’t wait to port there saw lol!! 😬But luckily it all worked out😅
Great video though, more knowledge the better I always say!
Thanx again Tinman!!
Great video! Im very much new to this. Do I need to check timing before and after porting my Stihl 025?
Excellent stuff Tinman, Just ordered a set of Verniers calibrated in Smidgets 😁
Hey Tinman. I use a drill chuck like yours and i found that using vacuum caps meant for cars helps hold the drill chuck tighter if you put one over the threads. It also helps insure you wont mess the threads up to. i forget the actual size sitting here but i all buy is the small assortment pack.
I'm going to try that Thankyou!!
@@tinmanssaws They make a couple style caps. the colored caps seem to be a little thinner. I use those because of that.
I've been watching the series so far I've learned a lot!
I just bought a 660 and a husky 550xp. They both seem great out of the box but id love to have them both ported. I just got them both 2 weeks ago and they dont have 2 hours on either of them yet. Id hate to ruin either of them but im wanting them to run like ones i see on TH-cam

realy intresting to see this. a know little bit about porting but allways learning something new.
Just started watching this series. I'd like to play with porting. Iv got a Homelite that is a good little ripper that would be good to learn on.
Love your channel Tinman. Awesome info sir. I'm learning alot from you.
Tinman I crimped an alligator clip to a piece of tie wire. Then you can clip it to a fin. It works on everything I've timed.
Awesome video. Well laid out. Its definitely addictive.
Tinman great work thank you for your kindness. Amazing information.
Kindness and love 💪🏻💪🏻⚡️⚡️🪓🪓
Great job explaining everything!!!
There’s a normal man’s Channel Locks...and there’s the Tinman size Channel Locks!
All I need to port comes from Tinman! Now I need a cheap saw and have my cataracts done 😄

So much Great Information Tinman, Great Teacher
I’m getting ready to rebuild my 026. What brand or brands to you suggest for long life also, do you know an approximate HP increase on the 44.7 mm combo over the factory 44mm. Thanks. Really enjoy your work.
Everything made great sense to me except transfer timing. How did you determine 122 degrees?
Thank you Tinman for breaking it down for us 👍
Thanks Tinman! Sure would be nice to have a collet setup on the timing wheel. 3 jaw jacobs chuck is ~.003" run out on a good day. Do you find that a 3/8 chuck will handle most crank shafts? I learned to not use rosin core solder too. Puts a some junk in the cylinder. Waiting with bated breath for the next episode!
What’s the easiest and best way to remove carbon from combustion chamber and band? Carb cleaner and pick/flat screw driver scraping takes forever
Anxiously awaiting part 3. 👍🏻👍🏻
Hey Tim man if I delete the gasket off the cylinder head and check the squish will I’ll have to re adjust the carburetor in rich or lean ? Or should I just warm the Saw up and run it a few minutes and do a plug check ? Any help would be greatly appreciate it thanks buddy
With these. NUmbers , can we use a spreadsheet to see the calculations , then we can put in some numbers to find the optimum timing.
Very well done Tinman!
Almost looks like you could put a husky 56mm 395 XP cylinder on that echo With some work . When I get a motor that's dirty like that I use purple cleaner with some dawn in a spray bottle and clean the heck out of it & then with the garden hose & spray it off with air & WD 40. I like your degree will set up.
Amazing teaching work! :)
Anyone maybe has a link where to buy a timing wheel?
The timing wheel on the camera v your eye is called parallax. It comes into play in shooting and surveying.
Tinman, I believe I have a rival for how dirty your echo was. I am close by if your interested in seeing it just for laughs. I’m going to tinker with is see if I can make it work. First pull rope broke, haven’t hardly looked at it since.
Very well explained!
very nice series! I am very excited about the next episodes!
Great video. Thank you for your time
Hey Tinman, question. Restoring an old Homelite 5-20. Wondering how to clean the cylinder and carbon off top of piston. Can I lite hone the cylinder without damaging it. Thx TM. Keep the vids coming.
Wd 40 and scotch brite cleans up the carbon...it's not fast, but it doesn't remove metal from the piston thus lowering compression. Lots of elbow grease.
KILLER KILLER work here, brother!
tinman, does it matter when timing your transfers with a ring which way you turn the timing wheel when piston is at BDC? And in general, when finding the timing numbers, does it matter which way you turn the wheel?
Thank you for sharing! :) I like watching this channel! :)
I have watched the video twice and I can't figure out where you come up with the 122° number for the 20° difference. When you use the ring, you stop it at 122°. How do you know that's where to stop it?
do you have a ported pioneer p- 62 w straight exhaust great cutter
Nice job tinman love your channel
Do you have recommended timing numbers for a 50cc general work/woods/firewood saw? Would the numbers discussed in this video work?
You should check out a ktm sx 65 cylinder they have a vacuum controlled power valve. Wouldn't that be cool on saw more bottom end and more top.
Thats a good idea
Im lost as to how the exhaust is 102 both before and after the base gasket removal.
That cylinder dropped 10-15 thou, but the degree of rotation didnt change?
Why?
I'm ready to know exactly what doing what to what port makes what happen, higher exhaust means less torque higher rpm, I'm ready to know the rest
Do you worry with the duration on how long the intake or exhaust are open? Thanks in advance
Did you ever manage to get this back together again 😂
Hey brother I'm still waiting for you to put that video up when the kill switch didn't work and you got shocked you said if you find it you going to put it up there I want to hear you jumping swear a little bit I bet me ..lol...as always thanks for the videos thanks for your time I always enjoy watching you.. hey if you're looking for some good bearings and case pullers stop by and talk to Matt Olsen he does some good work and John Reilly him and I have been cutting Pistons down and doing some crazy things lately all right brother have a good night will see you in the shop probably Wednesday right Tuesday be good to no pressure..jk
I have a question, can you work on an 1/5 scale 29cc rc engine ?
Thanks
Here’s a dumb question: doesn’t the flywheel key ensure that the timing of the saw is correct in the first place? Why else would there even be a key? I understand that this assumes that no other mods are done such as porting. But if all one is doing is a base gasket delete do we still need to catalogue timing? And what do these timing numbers even tell us? Shouldn’t TDC and BDC be 180 degrees apart?
About what does it cost to port a work saw if I send it to you? I’ve got a 6100 Makita/Dolmar.
Love the video make sense to a beginner like me
hey tin man drill a hole in a sacrificial piston or cut the piston in a pie shape and stick a small camera in there to see your transfer on the inside weve done it and it works
