What is the model of this Husqvarna Chainsaw? Help me figure it out as I tear down & look for clues!

Hey Everyone!
A while ago, a friend of mine gave me this Husqvarna Chainsaw to do with it as I saw fit. I could use it for parts, get rid of it, or rebuild!
Today, I decided it was time to dig into it and figure out exactly what it is. It seems to have a collection of different parts on it, and the only true way to tell is to do a disassembly and measure the bore. I am by no way an expert at identifying older Husky Chainsaws, so I'm hoping someone out there can help me!
I had some previous information that it could be a Husqvarna 61, 66, 261, 266se or even a 266xp.
Watch along as I check things out and try and decipher clues along the way to help identify exactly what this saw is!
Clues so far:
Top cover:
61
Cylinder:
Mahle
50mm piston, single ring.
50ZN13 W5 with “D” stamp
Flywheel:
Sweden OEM
501 52 52-02
114 SE W 652
Carburetor:
Tillotson Ireland
224c650
What would you do? Rebuild? Sell as is?
Cheers!

it does look like a 266!

[@DavesSmallEngines]

Hey Doc! What would you prescribe for this old saw? Try and save the cylinder or look for a Meteor 272xp kit? Is it worth it if I’m going to keep it for myself?

[@stellarproductions8888]

Yes, this can be figured out with solid research on your side, as well as excellent professional opinions from the community. This saw has been through the ringer, and for the record, my spidy senses were telling me this was an engine overheat issue rather then run with straight gas issue. Looks like I was right! I kind of like both your ideas on what to do with the saw. For a KZbin video, it would honestly be fun to see a top end conversion. :)

[@DavesSmallEngines]

Hey Stellar! I’ve got an offer above to get the cylinder cleaned up…. But the 272 Meteor kit is tempting!

[@chrisoxley7148]

Oooh ... exciting to see the consensis points to 266xp !

"66xp and will take up to a 272xp cylinder and piston if you want a better runner, defo worth doing with this saw, i have one i rebuilt and its a little ripper with the 72cc kit on it, going to need a lot of cleaning though

[@DavesSmallEngines]

I gave it to a friend who did the Hyway 272 kit. He loves it!

[@blackenedmagic888]

I'm not overly familiar with Husqvarna chainsaws, but you should be able identify the chainsaw by doing a search on the part numbers from the cylinder head, flywheel, clutch, etc. Yes, I know multiple chainsaw models may use the same parts, but it will, at the least, narrow down its identity to a select few models. I've had to identify a few Poulan chainsaws this way.

[@DavesSmallEngines]

Cool! Tinman helped me confirm it’s a 266xp!

[@rogermcdonald1607]

My uneducated guess is a 266XP saw. Dave you almost forgot to get the blue shop towel out! Lol. I hope you can get a reasonably priced kit for it and make yourself a nice saw.🇨🇦🇺🇸 Roger

Hey Roger! Good to see you back. I’m still looking!

[@larslindthomsen7370]

Hi Dave😊. Super video as always 👍👍👍👍👍👍👍👍. This is the 3rd time I try to write on Google Translate. Gets the pressure on something wrong 🤪. When I saw it I thought it was a 444SE. But it was not so maybe a 44 from around the mid 80. Maybe guessing far past 😉. Can you have a nice day. Sincerely, Lars from Denmark. PS Google Translate.

[@DavesSmallEngines]

Hey Lars! Thanks for the kind words.

[@dubbssawshop]

That is no doubt a 266xp!!!!!!The 266 and 268 are the only ones that used the 50mm bore. Converting to a 272xp you will need: 272xp Piston and cylinder, 272 intake block, carb bolts. You should be able to use the air horn that was on it. Also- the carburetor will work fine but it will be just a tad underpowered due to the 272 carb having larger jets but it will run no doubt regardless.

[@dubbssawshop]

The piston is the give away. 266 and 268 used 50mm but the 266 was the only one with the full circle around the bottom of the piston. The 268 only has the 2 skirts and no side skirt.

[@timberray9572]

I have two of these, I have run a 266SE right next to a 575XP and the old saw walked all over the new one. I have a few videos of mine if you want to see some examples.

[@DavesSmallEngines]

I’ll check them out! Thanks Ray.

[@carlmiller1034]

Hey Dave, Is just the piston and cylinder the main components in need of replacing? Or would the gas lines, seals, and carb also require servicing/attention? For me, I would just save it for parts. However, if you want to rebuild it for yourself, it would be a cool project. Would you keep the same size, or look to change it (piston bore)?

[@DavesSmallEngines]

Hey Carl! I’m not sure yet. Probably a carb kit at the very least. I’m going to rebuild it, I think!

[@Marty1959]

Rebuild it like new it was a great saw in its day

[@crazyman3157]

I am not familiar with Husqvarna but I watch THE IRONHORSE, his name is Harvey. I am sure a few people have heard of his channel. He knows his saws pretty darn well. Either way, good old saw. 👍🏻👍🏻

I will check him out!

[@ihd-3603]

200 series husqvarna possibly 266xp/se,268xp, or 272xp? 200 series are great starter builds as AM parts are cheap and plentiful and they are one of the easiest saws to work on.

[@dogeatdog42]

Looks like the 61 bell hopper was working on

[@DavesSmallEngines]

Hmm, I think it’s been determined to be a 266xp but I see what you’re saying!

[@timberray9572]

That saw was definitely used by a pro logger, the cover is not cracked, it was cut away for heat to escape. Another clue is that the muffler has been opened up, again for heat dissipation.

[@DavesSmallEngines]

Cool! Great info!

[@markmacdonald6452]

Id try to clean up the cylinder and put OEM piston in it, or look for a OEM kit on line for a decent price. The saw is a freebie, so take your time and try to build it into something. Those saws are getting harder to find, defiantly worth fixing.

[@DavesSmallEngines]

Hey Mark. Great advice. I was going to try and clean up the cylinder and find a meteor piston. Thoughts?

[@markmacdonald6452]

@@DavesSmallEngines I’d go with an OEM if not too pricey, but I’ve used Meteor in the past and worked good. I see lots of guys on line using them with great results. I’d like to see you get it fixed. Keep up the good videos, you got a a good knack for it.👍

Send me that cylinder brother... I’ll clean that one up no-change... 268 or 266...the transfer’s are just bigger in the larger... the 272 will bolt right up... the 266 intake is different shape then the 268 and 272... so you can tell by looking at the shape of the intake block...the 266 is smaller... the other two are bigger and actually looks like top left and right and the bottom right... I wish you were in the US it would cost you about $11 bucks each way and I’d clean that cylinder up for free for you. I actually only charge guys $20 bucks for the service so that they can run the high quality OEM instead of toss a great cylinder with some aluminum and bolt on a lower quality Chinese unit... the 272 Hyway titsnikasil with the popup piston would really make that saw wake up!!! Maybe Donny has a 272 jug and you can get a meteor piston kit or something... if it’s a 268... you have the right intake block already. As a side note...there are cheap aftermarket gaskets available for those intake’s but they are low quality and don’t fit quite right...you always want to spend the couple extra dollar’s and get the real Husqvarna gasket set...those cheap gaskets can cause all kinda headaches because they can have a tiny air leak and you end up playing with your carburetor tuning and start thinking that you have a carburetor issue and it’s the cheap gasket!!! If you can chamfer the edges of a cylinder then you can get away with the cheaper cylinder options in aftermarket...you really just need to realize that you end up being the last quality control inspector and plan on going over all the edges and making sure that the ports are nice and smooth... you are basically investing your time to save money for the parts.... get outside with the muriatic acid and PPE and use a long Q-tip to place the acid on the aluminum and let it melt... then use a 320 ball hone that’s just smaller than the bore to replace the crosshatching...with some 1/8” in and out as the slowly spin the hone with the drill!! You can take a 6” piece of 3/8” wood dowel rod and cut a 2” slit with a hacksaw to hold your 4” x 1” wide strips of emery cloth...160 will grab most of the aluminum then go around with the 320 to get a finished crosshatching...
