Basic work saw porting tips

[@KenAustin-i4x]

excellent Gordy ! I've been a motorcycle race engine builder for 50 years. I'm old. after building hotrod Harleys for a few years, I went on to tune race Kart engines, to me the ultimate in 2-stroke tuning. learned a lot. ported a lot. ruined some cylinders. your craft is making better use of tuning than my race motor work. way to go Brother.

[@AndyH-13]

One of the best explanations I’ve seen on porting for beginners.

[@donnywalker4691]

Great video right on the money

[@westcoastsaw1368]

Thank you big dog

[@jasonmichaeljimenez]

Just think. You have been working on small engines for 50 years, ported probably thousands of saws, and you spend your free time watching saw porting videos on KZbin. You the man, Donny Walker, you the man.

[@evergreenorganics]

One thing for new guys is buy yourself a $30 dollar digital caliper for measuring the thousandths. Figure out how many thousandths = one degree and take off only about one to two degrees at a time. A little goes a LONG way. When I port most of my time is spent in the transfers making them more aerodynamic. Great stuff Gordy, thank you.

millimeters baby.

[@MF175mp]

It's a different amount of mm/degree at different positions

[@evergreenorganics]

@@MF175mp no it isn’t.

[@MF175mp]

@@evergreenorganics sure is, at TDC and BDC it's 0mm/degree and in between it's a different amount in each position

We have snow here, made my log job muddy so I finally can have a day in the shop. A little = alot in porting. Get comfortable and take your time. I recently replaced the intake and exhaust gasket in a Jeep 4.0 I built and ported 20 years ago. It was really nice to be able to see the fruits of my labor again after all these years and 438,000 miles of reliability. The time spent on your builds will give you a higher level of confidence in yourself and your equipment. One will make mistakes but keep going, one day you will look back and be glad you did.

Very nice! It’s really funny but as a young dude going into high school I absolutely hated working on cars because I had to work weekends in my uncles junk yard… about 12-13 I started working on some of the stuff setting around because when my uncle would take off for his afternoon bar run we would jump into whichever whip I had got going and play dirt track racer in and out the gravel back roads that lead you back into the property! LMFFAO! About 14 I was talking with my other uncle about rebuilding an engine and had gotten some good basic information… so we set about on a ford fairmont wagon and it was a pretty decent 5.0 cruiser for our first official builder… my uncle Jonny helped me some with the getting my heads done by a buddy with a machine shop and whatnot… it ran a long time too! Mom drove it… we added a nitrous shot my junior year of high school but it only lasted for a couple months and then mom made me take it off… some teenagers were joyriding and she wanted to put them in their place as the wagon never made it past the multi colored primer stage and she scared the Holy Heck out of herself!!! A couple cuss words were uttered for probably like the 5 time in her entire life and I was in the driveway making sure she didn’t kill herself on the button… still wish I could have whiteness exactly what happened!!! My 3 year older sister said… we went really fast!!! 😂😂😂. Porting saw’s is awesome… people get all defensive about talking numbers and whatnot like they might loose some work over it? If you have a great reputation you’ll never loose anything to another shop! There’s a stream of guy’s who are getting into saw’s just for fun and the porting work is going to just continue to grow the more and more people get interested and involved… if the guy could do it himself he probably already would have… there’s just lots of guy’s who are trying to collect the information enough to know what they are talking about… it’s definitely not the space shuttle it’s a freakin 2 stroke chainsaw engine!

[@DaveyBlue32]

I really like your stuff I bought a 660 that had the muffler cover and spikes on it!!! Didn’t realize the whole weight of your duel port muffler front covers from that really fantastic thick hunk of metal!!! Not gonna bend that up!!! Very nice 👍 😁

[@timstiles9026]

Gordy, Sir i got a question... I want to get the most power I possibly can get from my Stihl MS362 can u offer any advice? I'm in Pierce County Puyallup Washington... I believe you're local to me... If you can help me figure out what I can do for the best result I'd be really grateful...

[@cajun3197]

Great explanation. I love exchanging port timing numbers with my buddies and learning what works for some and doesn’t for others. Then you find the common denominator of the what and why’s. That’s really a good way to learn too if you’re starting out find guys on your level or close to and share your ideas.

[@joesjunkgarage]

Absolutely fantastic sage wisdom presented here! Pay attention here people! I’ve been in the performance automotive, motorcycle engine building arena for decades.

Hey brother. Your spot on as far as my knowledge. I mean spot on. . Nice work bro. .. didnt know how digital even a gasket thickness makes on these little screamers . Not to often i run across a common sence mechanic and you have the goods . All and anyone who wants to learn something , needs to pay attention to you and your knowledge . Thanks man good to know there is others like myself that get after it and actually know what there talking about. Hey bro i eat sleep and thrive on these air pumps so i can pick up what your laying down . There very touchy and it has to be perfect or they wont run good or at all. 10 thumbs up to ya , pay attention people this man knows what hes sharing with you . 100 percent. . Thanks man appriciate you .

[@johnjelinek-g7b]

Really good explanation on atomization . I used to port and learned these concepts back in the late 70's early 80's . You sure can make a lot of difference from where you place rough and smooth surfaces in naturally aspirated engines . Not so much in force fed power though . Good video . :)

[@ScrewdriverTUNING]

Beautiful explanation on basic porting. I will be a watching all your videos because of this explanation keep up the great work🔥❤️‍🔥🧬

[@westcoastsaw1368]

Thank you

[@danieledwards1081]

Just got myself a Holtzfforma 880 clone kit saw, this is exactly the info I'm looking for to clean up the ports prior to final assembly on it. Hopefully will make a good difference right away as the casting looks pretty average on first inspection. Thanks for sharing the knowledge Gordy

[@comingtofull-ageinchrist6736]

this made sense to me because I watched a guy do the same for air flow on a muscle car and hearing some old experts from the muscle car era talk about air flow. It's about keeping the motor cool. I think the best way to relate the heat in a motor is for anyone who has over heated their brakes in a big truck; you lose your brakes. The same goes with the power in a motor! when it gets too hot, it loses power! the cooler you can run a motor, the more efficient it will be for long days of cutting! this was an excellent how to on increasing air flow without causing problems with the piston rings hanging on the edges. That part, I think was one of the top pointers on guidelines for shaping the ports for optimum air flow! Thanks, Gordy! Great video!

[@Mr_Clean]

Ever watch NHRA drag racing? You know why some guys play games at the starting line? Because the hotter their motors get the more power they build and then the other guy blows the tires off. And those guys run solid blocks. No coolant

[@gibbyrockerhunter]

I feel like you are trying to say the original comment is wrong. Dont forget the "whys" of the alc burning nhra guys. There simply isnt enough time for the thermal transfer to take place in regards to running coolant. There are many other reasons for that one instance, but bottom line is heat=energy. It doesn't matter if we are talking photons, electrons, etc. Heat is wasted energy @Mr_Clean

[@comingtofull-ageinchrist6736]

@@Mr_Clean there’s a line on how hot is good and when it passes that threshold it loses power! The principle can be seen in breaks overheating and losing the ability to stop the vehicle. I’m no expert but there is a balance to be attained; and air flow is key to anything, including to ignition of sparks that drive the force in the engine! Without air, no fire, so air is necessary for ignition and cooling, and engine experts played with this a lot back in the 60’s through the 80’s especially when muscle cars were a big deal!

[@kevindennison8619]

Great video! Honda discovered years ago that the intake charge mix and speed, over more volume made the most power. Polish exhaust, rough intake, and if possible increase intake charge speed by modification of venturi effect and distance to intake at the cylinder.

[@MichaelLeger-o1h]

Awesome video! Probably the best explanation I've heard yet about the mechanics of porting. Thanks.

[@danielbenedict9236]

I love it Gordy!! Good video and great information for those of us at the beginner level. I would love for you to talk a bit about the stratified design and how that may differ for porting purposes compared to the non-stratified cylinders. I don't think I have seen a video on that from anyone yet. Keep up the awesome work and content!!!

My porting stays the same between the 2 there are some tricks you can do maybe we can talk about that later on down the road 👍

I have that same vice! Love it! It was given to me by an 80 year old neighbor of mine about 20 years ago now

[@timtrax918artisan8]

You want asperation on the intake , picture the air and fuel across the ruff surface. It causes a turbulent mix. The exauhst is smoooth to get rid of it efficiently. I leaernned this 25 years ago with a two stroke racing quad. thank you Curtis Sparks

[@ToreDL87]

Yeah want that A/F in with velocity, dimple porting, whereas exhaust > smooth. Unburnt stuff hangs on to everything, even pistons, so, smooth & polished exhaust, don't give carbon deposits anywhere to hang on.

Thanks for this info. It makes a lot sense to me. It's about air flo and atomization for best combustion. The timing issues makes me think I might want to let those with more experience work on saws I need for work. I have a couple I might be willing to chance experimenting with.

Drawing a vertical center line on your piston to align with casting marks can be useful for holding your piston in line with where it'll run.

[@hillbilly4christ638]

The easier it breathes, the better. Yes you can take it too far, but these saws now are so restricted that anything is an improvement. If you want dependability, open it up. If you want a race saw, well, that can get expensive. They can run really well for a short time, but after that goodbye. Nitrous will make them run like a scalded dog but anything weak in there will let you know. Compression can help a great deal, but once again if you have too much pressure something will give way. Great video. Bottom line, make em breathe easy.

[@alessandromonizza8283]

Talking technically the intake should be lightly rough in order to create a very thin strate of the air coming through that is in turbulent flow. That VERY thin film of turbulent flow is gonna like insulate the rest of the airflow from the intake walls, keeping it as a laminar flow that is the one you want to get for the maximum airflow possible.
