Pt 3! Complete saw build! Intake timing! What the numbers mean!

[@dirtytsfarm2141]

I can't tell you how many times I've come back to you're videos. Thank you sir, how far you have learned me and given me confidence to TRY. Thank you!!!!!!!!

[@lewisfoster658]

You are the one of the best examples of the true man that believe in giving back to the next generation of youth. And not trying to take it to your grave and let the art be lost. Only the older men that had mastered thar art showed us that kind of love. You are the perfect example of a dieing breed. And God will truly bless you. And if thair were more of you this world would be a different place. Thank you sir.

[@tinmanssaws]

I once went too big on a muffler mod, saw was lean and couldn't figure out why!! Thankyou for your knowledge, I for one am really enjoying it!!

[@elcoutlaw1936]

Outstanding series! The knowledge you are passing down is priceless! Thank you for your time

[@kylegreen3442]

Thank you so much for sharing ur knowledge and wisdom on this. I learn everything buy watching a d doing. And ur the only one that talks in depth about port timing and wgat to look for

[@jamiedalluge9472]

Great series for this build so far. It's fun to watch a guy in his element.

[@s.mcglothlin8986]

Really appreciate you taking the time to make these videos. After watching all your videos (like 10 times each), im feeling confident on taring into one of my own saws and building it. Thanks again.

[@tazman-kennyfuller]

I absolutley love this thanks Harvey for the good info, even on the exhaust porting with the size of hole you can go with. 🌲❤🌲

[@jaycummins8720]

I am enjoying these videos. Thank you for putting these together.

[@richr1870]

Outstanding video Harvey! Very thorough explanation my friend! Peace!

[@ronledbetter4993]

Thanks for these videos. I'm getting ready to port a 365 Special. You mentioned Mike Acres has a nice timing numbers chart. Also Kinzy made a graff. Can you tell me where I can find both?

[@michaelwhiteoldtimer7648]

[@michaelburton5760]

Make it rain big man I am learning Love what you doing

[@Kronkus36]

Very interesting Harvey, I could watch videos like this forever !!

[@evankibbe590]

Gonna have trouble waiting. 😊😊😊😊👍👍👍👍👍❤ very interesting.

[@johnclarke6647]

Got my new Stihl cylinder and piston in for my ms 460. I am ver pleased with it. The transfers look beautiful, a nice slope. The intake and exhaust may need a very little bit of work. I am waiting until I get my degree wheel befor I do anything to them. I am surprised how good the ports were chamfered. A lot of difference between this cylinder and the Farmertec I have used in the past even the edges of the piston were broken. I probably will not touch it because it weighed 77 grams. I will bet the timing will also be beautiful.

[@davidray4772]

This is awesome....its like goin to a Japanese steak house...its all prepared right in front of you!!! Look forward to runnin some of your saws...

[@kevinparent8843]

i am listening regiliously these videos. ill do my first porting on my 390xp and make sure that i will shoot you a video of mine cutting in wood ! i swear ! cant wait ! ill try to put hyway cyl and meteor piston. if not, i have the hyway in backup

[@Indeewoods]

These videos are just great it’s like being in college class again but in the comfort of my living room infront of the woodstove lol. And something that is far more interesting!! So talking about blowdown/exhaust roof height how does a longer lets say 38mm stroke engine react to a high exhaust roof vs a shorter 34mm stroke engine? I would think the Longer stroke motor could tolerate the tall roof to make up for the low end grunt loss?

[@jasonhaskins4554]

I love the Three amigo's Harvey, Buckin' Billy & Steve

[@jonathanharsch3243]

Awesome videos can't wait to see the rest

[@lilaboys4257]

Thanks for showing us this very awesome stuff!

[@CMLovejoy]

Thank you everything simple and clear.

[@pdaddyblake]

Talking about the Reeds saw It would be nice if you can make a 70s air cooled yz 80 cyclinder and head with the reeds and carb already on it fit on that bottom end been trying to do some research on stroke ,bolt pattern,wrist pin sizeing and stuff but all my old bike parts have been long gone 😁👍need some reinforcement from someone with some old cyclinders they can donate so you can do some sifering

[@j.chrisbeck7492]

Loving the series Harvey !

[@ronsilva516]

Good info I need to do my ms 391 rebuild I need Som more power on it to Handel the 20’ bar better in big wood that is oak

[@DaveyBlue32]

Do you have a link for contact for the gentleman who turns the little hub for the degree wheel??? Please share if he sells them for me.., that will make it easier for me....thanks...👍😁

[@kingkevin160]

Ironhorse, I keep talking about finding a 394, but I keep hearing you talk about Reed valve saws and I have a McCulloch super 250 which I believe might be the last of the Reed valve style saw, someone correct me if I am wrong please. I haven't had time to go through and and try to revive it yet. Would it be something you would be interested in working on once I get moved and unpack my saws? Either way super enjoy you channel and this series.

[@theironhorse6600]

After running that 390 I just built I would look for one if I was you! Gobs of power and much lighter than 394!

[@codelicious6590]

Why do some people say that the exhaust port should be larger in the bore end than the pipe end, and some say the opposite?

[@wildmanturner]

Could you tell me good target numbers for a MS440 stihl?

[@albertgregorski6877]

Hey Harvey love your videos I also have learned alot have alot of 371 and 372 carcasses and have 3 non xtorx 372xp new in box if you're interested in parts contact me. Love this stuff keep it up!

[@kevinparent8843]

i don't understand the intake numbers that you share, you got a 76 closing and 104 opening, and you want to do a opening at 70degrees ? so you come from 104 to 70 as i understand ? its like more than 1/4 inch as i measured.. when you turn it at 70 you have a gap also, so im not sure if its an error or not..can you help me with that please, i think i dont want to grind before being certain about it ahah 😅 myfirst porting also

[@joecochran9976]

Not your 1st rodeo, looks/sounds like the bull riding champion!! Great job!

[@nateb8245]

I didn’t quite understand the muffler guideline. 5/8 of the the of exhaust port becomes what? Diameter of the muffler hole?

[@theironhorse6600]

Exactly!

[@phogelbice]

@@theironhorse6600 width or area? if the port is 1" you make the muffler exit 5/8"?

[@timhart2652]

Wow!! Nice work

[@j.chrisbeck7492]

Expansion chambers....suck less back in....sort of...if tuned properly in the pipe, it times the sound wave...and the bounceback

[@jeffjohansen4945]

This is fascinating !

[@mrj7872]

Does exhaust work give you anything without porting because I can’t do that

[@theironhorse6600]

Yes!

[@1944chevytruck]

thanks! good video!

[@joeskretkowicz3218]

do you grind both left and rite top of piston

[@theironhorse6600]

Yes!

[@twobears1224]

Where do i get a timing wheel??

[@theironhorse6600]

eBay! Get the small one!

[@twobears1224]

Thanks..i,am very new to rebuilding saws but i have a 272 and 268 that are worn out so i thought i,de learn how to do it.i,am enjoying your videos but i can see i have alot to learn before i put a saw together. ;-)

[@mikeyyoyo6464]

Love it 💪❤️👍

[@mrj7872]

And I still need an air filter for a McCullough 1010 if anybody has one for sale or trade

[@j.chrisbeck7492]

Try amazon

[@bikerdog5554]

Thankyou ..Boom

[@mattpilcher1952]

Billy just called me. I just bought a p60. He said to send it to you

[@theironhorse6600]

Love to! Email me! [e-mail]

[@j.chrisbeck7492]

News Break : Christmas comes early for Harvey !

[@eucalyptusleemcconnell8314]

Nice t shirt iron horse rock's alright

[@williambaker2441]

I have a 051 av I’m trying to restore i use to use it a lot but it’s been several years since I’ve used it. It have a 42” bar at the moment but I’m gonna drop down to a 32”. How can I contact you about getting some porting done to it. I’d try it but I really don’t want to mess anything up

[@aaronschoessow9567]

The way I will remember is ( make my Ex (Exhaust) shorter cut her high heals off. And on the intake make it a little taller.. lol

[@aaronschoessow9567]

Now im backing up to re watch think I may have gotten that wrong

[@jimmysixfingers9796]

👍
