“Practically a new saw; well, apart from all the old bits …” I love your dry wit combined with your enthusiasm. It makes you very watchable, even though I haven’t a clue what you’re talking about, as I’ve never thumped iron, nor dismantled or renovated a motor.
The sound of a chainsaw being used in the background just adds to it.
Few tips... Gudgeon pin clips should sit so that they're open at the bottom.
Use lube. Especially on the piston. A smoky first start is a good one. You want a good liberal coating on the bearings and the piston etc.
When you put the gaskets in it helps put a smear of grease on them where they're sealing water or oil and hylomar where they're sealing compression. Only a small amount is needed, but it can make a big difference.
Max, you are a fantastic and witty storyteller... would you consider doing a video about your younger life and what inspired you to pursue blacksmithing and live off grid? I'm sure now that you have a lot of subscribers that there would be many people interested. Keep up the good vids👍
A tip : Never put the piston pin clips in with the open end in the middle -Either at the top or the bottom is the proper way so that the up and down thrust doesnt unseat them .
I don't think it's a "how to" just Max doing his thing and sharing stuff with us all, so thanks Max, your content is much appreciated.
I've broken so many (cheap and nasty?) aluminium castings in my time that any kind of force applied to any casting fills me with dread.... this project's had me on the edge of my seat. ;)
Chicken's looked like they were mounting an expedition to discover far off lands as they went off up the hill.
The internet is a great source to solve problems. Nice job. Always good when you don't have bits left over.
That one washer left over, that lonely, lowly washer. That's the real story here... How it found it's confidence again.
true to your name, you manage to find a way to incorporate blacksmithing into the most unexpected of jobs.
Great work. In the old days I was taught that a cigarette card was a good measure of the distance between the flywheel and the magneto. (About 16 thous from memory). I am 76 now and my on farm training first took place when I was about twelve years old. I guessed you would end up making up the throttle linkage wire!
Brilliant, nothing like a few beers and watching a chainsaw rebuild for Christmas 🍻
Arrow towards the exhaust always Max, the pin is to stop the ring rotating and catching on the ports
Not complicated, but an alien concept in a throwaway society. Proof that well made machines will give you many years of service, with good maintenance and quality repair work. Just look at Trigger and his broom!
Quick way to check condition of engine is to remove the exhaust, this allows you to view the piston skirt.
Good job Max. Handy hint a bit of plastic from a shirt box works well to gap the maggy just let it touch, tighten and remove the plastic. Gapped.
I seem to remember that the wire link has a sort of z shape at the end which is threaded through the carb spindle and stops it falling out.
Hi, I’ve repaired a Stihl 023, piston change and stumbled on a helpful hint to save damaging the cooling fins was to put a small rope in the spark plug hole to stop the engine rotating which allows you to undo the nut on the clutch and timing/cooling drum. Simple but can be applied to many single piston engines. Hope this helps for the next repair. Great videos. Thanks. 👍👍👍🇬🇧🇬🇧👍
Inspiring, as you said, it gives me confidence to have a go myself. Thank you.
The pin is to stop the ring rotating and getting the end caught in one of the ports.
I saw the carb linkage at 9:15 in original video by your left hand! It was on the workbench in all the muck.
Arrow points to the exhaust side, which is important for not blowing up your saw again
Well done that man, great fix for the linkage 🙂
My guess is that the carb wire clip most likely came off in the sonic cleaner and was thrown out with the dirty bath water! However, you got around the problem so, well done !!
There was a very nice chap with a video of stripping down one exactly the same as this - you should have had a look at that to remind you how it all goes back together! 😂
Part 1 & 2 I learnt heaps from, thank you so much bud!
hope you replaced the crank bearings and seals other wise you will be doing it all again when the seals on crank let go and cook the engine. you will need a thread lock on all screws. the air filter needs two stroke fuel on it to help with its filtering
You are a gentleman with many talents with determination of goals mending and creating many objects and many projects especially with the perseverance with the goal of compensation, I'm not a individual that is Impressed very much at all or educated as such, more of a lone wolf.... Hope you and Mark will do another Kermit post soon !!!. Thank you for sharing the recession of the most essential living in the woods. 👍
Great hands on video as usual and great seeing true free range chooks. Best wishes from Australia
Partially blocked fuel filter and air leaks between the carb and intake port can kill a two stroke. Either will make them run lean. It's always worth pressure testing the crankcase before and after a major strip down.
I meant to mention on the part 1 video, that the taiwanese Hyway pistons and cylinders are what we are all using now when we can't find a meteor. They have come along way and now there cylinder coating process is identical to meteors.
Brilliant! Inspired me to strip down and clean the Dyson...which is a bit more my level.
Dyson🤣🤣that genius who invented the disposable hoover to save on disposable bags 🤣🤣🤣. All they had to do To make him a genius Was uninvent the reusable bag🤣🤣🤣🙄
Great job but I would like to add one note of caution. When using ball end allen keys be carefull not to use too much force. The balls can snap off and get stuck in the bolt. if that is at the bottom of a hole then they can be almost impossible to get out.
good tip, also ball ends dont get as good a grip, and can round the hex in the bolt, as is currently being demonstrated by the captive bolts in my car's targa top!
Fascinating to watch your process. Thanks for sharing. 👍
Great job , fantastic entertainment. Well done, many more years left in that chainsaw now.
toothbrush is the best thing ive found to clean a chainsaw
A business card or the cardboard from a pack of tobacco rolling papers is a great way to set the magnito/coil
Hitting sideways on housings/crankshafts displaying axial force through the bearings. These are radial bearings.
This is somewhat of a no no…
If the bearing is already in the casing, push only on the inner race to get it on to the crankshaft.
Really satisfying video.
To quote your conclusion to the video...."absolutely flippin excellent". Thank you, Max, for two lovely videos.
when you put the saw back together and have extra parts i have a fully working 1966 homelite 75 horse chainsaw never let me down she is ported and polished and weighs a fair bit .
That was brilliant. What an amazing sense of achievement you must feel.
Should last until the beard has turned grey
Ah, "The Mystery Of The Missing Wiggly Bit", the title of your first DIY chainsaw repair book?
i rebuilt an old Husskie 346XP.old saws are the best :o)❤
Great to see a successful rebuild with some clever improvisation for the missing part.👍🏻
After being beaten with a hammer, the chances of that little crank still being properly inline are about zero! Its VERY easy to warm the inner race of a crank bearing with a heat gun, which will make the case halves go back together really easily...............
It still works tho, doesn't it?
@@uk_prepper6775 Its very simple to do the job properly, so why beat shit out of a precision part with a hammer, due to not bothering to find out how to do it correctly?
Looks as good as new, runs as if it's new too, great video
Great job max. Works like a new one. My g tech hoover is about as far as I would go but still satisfying when things work better after a good clean.👍👍
Good video that thanks, not as complicated as I expected. Might fix one of my 4 broken ones!
I watched the 1st video and the link was resting on the cylinder at about 7:40, then on the bench in some dirt. at 8:40 you had obviously cleaned the bench. Guess the wire is in the bin now. Well done on making a new one though.
Well spotted. Easy to lose as it fell off rather than getting taken off. Between 8:12 and 8:15 , it gets knocked round as the saw is turned. You can see that it is like a question mark shape. Then it's gone with the dirt. Hopefully the bin hasnt been emptied and it will come to light.
Another great video Max. I saw you at EMF, said hello as you were going into the null zone on Saturday night 😀
Hello Alan!
I'm getting 'Trigger's Broom' vibes from this one 👍
Actually way better than a new one :)
Thumper nice job, And you remembered not to forget, which is a bonus, great job ! From Steve near Chester England 🇬🇧 where the Roman's once lived.
A vary satisfying repair - nice one!
congratulations!! well done! great inspiration to repair own stuff :)
excellent job max you can use an index or recipe card to set the coil to the flywheel to give you the proper gap between the two
I probably would have changed the main bearings as well, as You already were as deep into it, but that was obviously not yet necessary. Ain't they cute little lumps, those tiny two stroke engines? So few parts, and such an umpfta! She'll thank You for the thorough cleaning with less heat and more constant power.
I would not exchange my old Husky for another brand of chainsaw, not even for two brand new ones.
Huskies are nearly indestroyable unless You try really hard and go with a bent bar (sic!), no oil or the wrong fuel.
Awesome 😎
Great vid, thanks as usual
Amazing job mate. Thanks for sharing this with us.
Nice job on the rebuild, I did not see you replace the crankshaft seals. Did you off camera? These can harden over time and leak resulting in less compression. It did run great though. Btw seeing you learning on the job I don't think you owned a moped as a kid. :)
More importantly if the crank case seals leak that results in the piston drawing excess air in and resulting in a lean mixture which only ends Badly for a 2stroke.
I wondered about the crank case seals too ?
Well done Max great job well worth doing 👍
Good job!
The only trouble I’ve had with my Husky’s has been fuel pickup pipe in tank. They split. 👍
It's always the think that goes ping that slows down progress, looking at where the linkage goes, it's probably meant to be shaped in a way so that it hooks into place from the back of the throttle plate and then zeds around into the clip on the throttle trigger bit, so it can't fall out either way, but at least it does fail safe at idle if it does pop off again... :)
11:15 , god for a second I thought I was watching teletubbies .. lol
You make it all look so easy 👍
Just watched these two videos in the wrong order. Part 1: 8m37s "Bendy wire by the cup!", 8m43s "Bendy wire swept away...nooooooooooo!!!"
Top stuff, now remember to strip it & clean it once a year it out live the both of us :)
Result! 👍
Excellent, you've made a like new saw for a fraction of the cost of a new one, with proper care it should last a good long time
Great Job Max ! One Happy Maximus Have fun Cutting!
Hot knife and butter spring to mind!
those are a fine saw. we had a 266 that i used for years until i cut a giant maple in July and overheated it. it was a heavy old beast.
well done
👍👍👍
That washer that you were wondering where it went goes on first behind behind the oil pump drive gear it does on first then the drive gear goes down over it
Proper job!
Nice work Max!
So glad to see you know the correct way to start a saw,I see so many idiots on YT drop starting them.
Throttle clip nees a z shape, at each end, you locate the bit on the throttle first then the slot in the button link allows it to be pressed in from the top
Hi. I've just subscribed to your channel. Really liked the rebuild and I've done one recently on a Stihl 038 Magnum. I used the same piston from same Greek supplier. No issues as of yet. Ps...dont gave the chain too tight.
I seem to recall something that went flying when you disassemble the saw in the previous video.
A great job :-)
Clip from the piston 👌
all circlips run away from home eventually.
@@edgeeffect the rich ones fly away first class 🤣
Your chain is slightly too tight. What ratio fuel mix do you use? Looked a bit pale. Would cause your saw to run too hot. Adjust gap between flywheel and magneto with business card thickness paper. Tighten down mag and pull out card
Another CZcams video installs a piece of paper between the flywheel and mag coil, which when removed, gives correct gap between them
You must have been feeling a little saw.
Hopefully it's still going as strong after sawing your wood
👍🍻
That was great!
Maximus the reassembler like James may😂😂😂
In part 1of your video @8:26, I can see the throttle linkage on the bench amongst the clogged together sawdust. Could it have been swept up, and in the bin?
Lovely job Max, nice renovation. the dumper renovation might be next ??
If it was my project, that left over washer would go on the crank shaft before assembling the crank case :0
When we completed the space shuttle, one of the major steps was checking the box of bits to see if anything was left over, which we found was the case, so we cracked on!
Zeer goed gedaan!!
Brand new piston and ring hardly any lube .. I know let’s run it full chat first go…. 🙄great vid but a little running in would have been better…
New saw like Trigger's broom? :D
It does concern me that this sort of thing won't be possible with new tools.
On the one hand battery electric things are more efficient, quieter, less to go wrong, better in many ways. But long term fix-ability.... maybe they'll just never go wrong?
I'm concerned. Everytime I pull a small engine apart, then together again, I discover the manufacturer put in too many bolts...there's always one left over and runs just fine, so clearly you've put in one too many bolts. Luckily I haven't pulled the same motor apart more than once...you can see where this will go.
