How to port a chainsaw part 2: Timing your cylinder (echo CS-670)

[@thadstuart8544]

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

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

[@shapeshifter7753]

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

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!!!

[@ozdatman]

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.

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!

[@shapeshifter7753]

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🙂

[@vintagesawyer6246]

Also . To not strip them .....turn screw backwards until you feel it drop into the threads. Then turn forward . 👍

[@foreverwood1963]

Thats what I do as well

[@rydplrs71]

I’ve used aluminum foil, but I bet trimmer line is better for plastic. It would certainly be easier.

[@speedbird561]

Small section of an appropriate sized zip tie also works a charm….

[@nathanmcdonald1585]

Thanks for your time man. Big steps with 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....

[@Killinit33]

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.

[@johnhudson6469]

I appreciate your slowing stuff down to a beginners speed! Until I caught a cutaway video I really didn’t savvy 2 strokes. This is awesome!

[@troutman1115]

[@chuckuu9294]

Once again Mr. Tin man. You hit the mark. Great great teaching video. Keep up the great instruction. Thank you

[@truegritbulldog]

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!

[@sppl8366]

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👍👍

[@robcole8218]

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

[@tinmanssaws]

Welcome rob

[@rydplrs71]

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.

[@GreatLakesLogger]

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!

[@ClintsHobbiesDIY]

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.

[@sagerman6779]

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.

[@treebunker]

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

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

[@_JamesBrown]

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.

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.

[@tinmanssaws]

I'm going to try that Thankyou!!

[@Shawnf1977]

@@tinmanssaws They make a couple style caps. the colored caps seem to be a little thinner. I use those because of that.

[@jurpikag]

Everything made great sense to me except transfer timing. How did you determine 122 degrees?

[@madmodifier]

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!

[@jacobhicks7959]

The timing wheel on the camera v your eye is called parallax. It comes into play in shooting and surveying.

[@meyer412]

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.

[@Welshwizzard1]

With these. NUmbers , can we use a spreadsheet to see the calculations , then we can put in some numbers to find the optimum timing.

[@bennyjustus]

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?

[@stephaneracicot791]

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

[@speedrcr968]

Do you have recommended timing numbers for a 50cc general work/woods/firewood saw? Would the numbers discussed in this video work?

[@clarencetrice4442]

do you have a ported pioneer p- 62 w straight exhaust great cutter

[@reillystsb]

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.

[@ocsplc]

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?

[@customcutter100]

Do you worry with the duration on how long the intake or exhaust are open? Thanks in advance
