Hello Mr. Harvey, I hope u and the family r doing well. This is NOT boring to me at all. I could watch u do stuff like this all day !! Tht new tool is the "cat's meow" ain't it, I ❤ watching a master at work. U make this look so easy, God bless u Mr. Harvey.. 🙏🙋♂️🤙
I just want to say, thank you for sharing videos like this. It’s hard to find the correct info online about this. I’m new to porting and just did my first port on my 372. It lost power in the cut lol but it’s a start! Thank you for all the videos! I know what I did wrong thanks to you and look forward to progressing! God bless!
Foredoms are awesome. Very generous of Tony. Glad you and the Tinman are enjoying your new tools.Thanks for getting more in depth on the porting. Don't mind watching the grinding at all. Thank you!
Iron horse I would like to thank you for teaching and passing on some of your great knowledge. Between you and Tinman the both of you have shown that it is not a great mystery and how easy it is to get good reliable power out of a 2 stroke motor. Rock on 🤘
This is incredibly interesting, learning the characteristics and the movement of an air charge is amazing. I would love to see this on a smoke bench, I could watch for hours!
Love it Harv. Thank you. This info is awesome. I love learning more and more about how the two stroke engine works and what makes power. Love ya brother🌲❤🌲✊🪓
My Dad was a Dental Technician after he got out of the air force. He used the same burs you use. But from 1968 to 2006 he had to chuck them into a bench grinder. He would bring the chopper to the bit and do the grind. Thanks to Toney you can get right on it. Grate to see you. now back to the show .03 seconds into it.
Harvey your content is fantastic. Thanks so much for sharing. I recently ordered myself a foredom with that exact same right angle grinder. Been looking for an affordable one for years. I was a little worried about the quality of the right angle grinder as it felt a bit rough and noisy but so far so good. Sure gets a guy excited about porting again!
Awesome, took me years to aquire one aswell and you'll never believe where I found mine at..lol at a damn good will foundation, there was a tool bag with lots of Dremel/grinder bits and stones etc and in the bottom wrapped up in a crown royal bag was a little 90degree porting tool that is rather old as it's the cast aluminum or magnesium body, made by Chicago electrics from what I could make out on it, paid 25$ for the whole bag, came with a couple old Dremels, ones with the long flexible head on it, Wich are pretty nice. Cheers and happy porting 🍻
Ha, yes, time will tell on these. I ran mine in and now will clean and lube with some moly grease as is commonly used for constant velocity joins on front wheel drive auto axles (the black stuff). I'll keep you all posted.bearings seem okay still but I'll clean and lube those also.
Was always tought to angle the transfers towards the intake and away from exhaust best You can so that it doesn't make it easier to get sucked out of exhaust port prematurely, am by no means an expert but I have done quit a bit of successful port work, started out on saws and Weedeaters and worked up to vintage motocross machines up until power valves...haven't played with any of those jugs. Great video,you good sir just gained a sub🍻
You are correctable angling the transfers towards the intake because when blow down happens you don't want all the fuel charge sucked out the exhaust porting isn't a boat just hogging out the transfers as big as you can he did absolutely no measuring transfers need to all be the same size angled the same way his exhaust port is absolutely horrendous there was no planning of the port at all all he did was took his car by bit and just wallowed out the exhaust as big as he could get it with absolutely no thought into port timing I would imagine on one of those small motors over 200° duration on the exhaust port is probably around your limit so if he did the port to wide it'll catch a ring if it's not chamfered right it'll catch a ring the shape of it isn't even close to what it needs to be there's no symmetry to it I don't know what more to say I do this stuff on like banshee motors and stuff that hundred horsepower plus so anybody that takes this video and tries to apply what he's doing all you're doing is destroying a cylinder you can't put material back in
Wife: “Hey, what you watching?” Me: “Ironhorse doing some port work with a new grinder.” Wife: “what’s port work?” ...25 mins and three diagrams later... Wife: “so why don’t people just buy a more powerful saw in the first place?” Me: “errrm...ok...I’m going to carry on watching this now love.” Equal rights but not the same 😂
Harvey because of you, Bellhopper, tinman, & Donny walker i will be diving into my first saw rebuild, a p3816 poulan, any tips you couls share would be greatly appropriated thank you this saw will go to the little man if it works out so it will remain close to stock!
Bellhopper has info, but usually does more extreme builds on the little junkers. Check out J&S Chainsaw. He does a bunch of the old crappy poulans, and has a bunch of info, and does a practical woods porting. Lots of guys don't mess with the little saws, because they don't use them. The exception is the tree saws - 200T and similar. They are pretty hot to begin with though, and usually just a muffler mod is enough to wake them up a bit. Some of the echo and china tree saws (top handle) can use a little more help (air filter mod, timing advance). Most guys add intake duration to your little poulan by cutting the piston bottom a bit, for a little more intake duration. Hope that helps someone.
Thanks for sharing your knowledge! A few oddball questions for you if you are interested. Does piston weight matter on a 372xp? Any difference in weight between the single ring and double ring piston? Is the crankshaft the same weight/part number when they changed from single to double ring? Some kits come with 1.2mm ring(s) some come with 1.5mm, any preference or thoughts? And for the probably the dumbest question- Can you run a single ring on a double ring piston?
The only thing that baby's lacking is curse control. Although I was never a fan of cruise control it might be handy. I'm a firm believer in self control its alot harder then one likes to admit to keep anything from wide open all the time. Nice and easy plenty on low rpm power only burning extra fuel running high rpm
Hey iron horse I’ve heard of the legend bing from the area! Your in the woodhull area I’m up in the kanona area ran stock saws my hole life just learning about mods
I know this video is a little bit older but I dont want to hijack one of the newer ones to ask this. Albeit a farm and ranch saw, I have a MS290 that I did the 390 big bore kit on and it was a fun thing to do and made a difference but I'm wondering now what the divider in the middle of the transfers are for and as you know those saws have an extremely low case volume. Could they benefit from grinding that divider out of the lower part of the transfers below the stopping point of the bottom ring and opening the intake up as much as possible to allow as much fuel and air in and into the cylinder by the opening of the transfers? Also if I windowed the piston some would that help? I also know I will probably destroy this thing instead of getting it right but I don't have alot of money in it and I really want to know how much difference if any it would make. For the record I am also a certified diesel guy so I have a few credentials but not on two stroke stuff. Any thoughts would be appreciated
Iron Horse are u getting these cylinders to scavenge a lil bit more flow this way ? Or decreasing the flow or down cycle scavenging? Guarantee this legit question will not get no response by the Mythical Ironhorse him self. I’m not trying to troll one bit I’m looking for a reasonable debate on ur thinking here. Then just maybe then we can touch on just how u come to the final decision on ur timing numbers in general. Since there is a overall method to mapping out all cylinders. Some rules to follow. Anything outside of tht it’s just throwing darts at a dart board blindly.

Your explanations help me understand what your doing but more importantly why you do it. Thank you for sharing.
Foredoms are awesome. Very generous of Tony. Glad you and the Tinman are enjoying your new tools.Thanks for getting more in depth on the porting. Don't mind watching the grinding at all. Thank you!
Grinding videos are never boring, i enjoy them. Love all of the little tips and tricks!!!!
No part of this is boring. The step by step makes things more understandable. Your a great asset. Thank you.
I am pretty sure that Iron horse like the new. Porting tools. Look at him go. Love it look out him and tinmam have toy's.
Iron horse I would like to thank you for teaching and passing on some of your great knowledge. Between you and Tinman the both of you have shown that it is not a great mystery and how easy it is to get good reliable power out of a 2 stroke motor. Rock on 🤘
another great video. thanks for showing right angle attachement !
This is incredibly interesting, learning the characteristics and the movement of an air charge is amazing. I would love to see this on a smoke bench, I could watch for hours!

Thank you, sir!
I found only one way to give a Video more than one "thumbs-up".
This:👍👍👍👍👍👍👍👍
It is a privilegue to learn from you!
It would be good to see a dyno test Before your work and then after the work. thanks for posting. that took you a bit of time to do.
Can sense the joy in your voice with the new tool. Great vid hope everyone doing well in family. Be safe and be careful.
Awesome video Harvey. Thanks for the knowledge. Cheers from Tassie.

Thank you. Your channel is awesome and I am very grateful for people like you on TH-cam.
So nice of you! Thanks so much!
nothing like a good tool that is working well

Thanks a lot Harvey this helps a lot and certainly not boring!
very nice job way to demonstrate it. you the man!!!

Equal rights but not the same 😂
Hell No!,,This is some of the best content on youtube!
Ive been looking for a Channel like this for years,,Keep up the good Work!!
Thanks for sharing Harv. Lookin good.
I like seeing the comparison to the bike cylinder...I know saws need more flow.those factorys hold out on saws...turn them up let them breathe
Harvey because of you, Bellhopper, tinman, & Donny walker i will be diving into my first saw rebuild, a p3816 poulan, any tips you couls share would be greatly appropriated thank you this saw will go to the little man if it works out so it will remain close to stock!

its going be intresting see that saw running,aim sure its going work very good
Awesome video thanks again mr. Harv!
I would love to see more transfer port porting videos.

That grinder is pretty slick.
Thanks for sharing your skills

I'm a firm believer in self control its alot harder then one likes to admit to keep anything from wide open all the time. Nice and easy plenty on low rpm power only burning extra fuel running high rpm
How cool would it be to have power valves on a saw hum
That’s what I’m talking about. THANK you my friend. You are an inspiring feller. 💪🏻🦾🦾🪓🎯
Golden info! Thanks Harvey!
Harvey is Barb ok now, i hope so
Hey iron horse I’ve heard of the legend bing from the area! Your in the woodhull area I’m up in the kanona area ran stock saws my hole life just learning about mods
Great vid bud. Question what is the name of your porting tools? I want to order them.
Foredom
You’re right Nader doesn’t forget because you are horsepower the great Ironhorse
I think your going to have some amazing things happen now that you have that grinder!!!!😎😎😎😎🇺🇸🇺🇸
Love it Harv! good man
I’d love to have you do some work on a saw for me.
Lunch time and watch a Iron horse video the best
I know this video is a little bit older but I dont want to hijack one of the newer ones to ask this.

Hey Harvey, nice job...
Harvey your cooking with gas looking good

Actually this is a legit question that deserves an answer! I will make a vid this weekend covering all of this! And I’m not mythical! Just a man!
Iron horse my friend. What is the model and brand of your rotors tool your using here?
Me likes it. Thanks brother
Chinese on eBay! Double helix and they are the best!
When porting the transfers does it need to be the same all the way in or should it come to a taper so it compresses the air
taper
+++++++++++++ Are the channels ground on both sides of the cylinder or only on one side????
This would help high mid or low power? Overall power it depends on duration and timing
IRONHORSE what grinder do u have where can i find 1 with the heads that change
Hi invite to a friendly competition from down under Australia, Chinese chainsaw underdog competition part 1 rules cheers kevin
Awesome
New porting tools! Now your cooking with gas...
1st like thanks
Does this actually work 🤔🤔

OK maybe I got ahead of you
