Husqvarna 266 question

[Stump Shot]

Have one metal tank from an early saw to build a 61/66 with. Been stashing stuff for a while now. I've only seen one other on a saw which was an early 266 SE.

There's not much on these saw's that stayed the same. Tanks, brakes, crankshaft, flywheel, coil, carburetor, cases, muffler, top cover different cylinder makers, piston changes. And yet people complain about the couple changes on the 562xp. Lol

At least three different starters that I know of.
Would think it would be hard to fix these with so many parts made for them, but actually very adaptable to all the new parts still available. The windowed 268xp piston(replacement from Husqvarna) or the Meteor replacement piston is a good performance upgrade to these saw's over the original full circle skirted piston.

Thank you for your starter fix on mine.

That is to cool. Are you getting close to building it?

Just in my mind. Lol

I think the '81 start date is correct, 266's had a very long run, well up into the 90's.
I also believe I've read that there was a 166 for a short time, between the 162 and 266.

Weren't the 625, 630 & 670 all in the same boat?
I know they had some differences between there Husky cousins.

Yep. 625 and 61. 630 and 162se. 266se,268xp and 670 were mostly counterparts. The 66 I don't believe is in the same family

 

[wcorey]

66 is just a 61 except with the same 50mm open port cyl as the plain 268.
Made in the Tomos factory...

Just occurred to me that the 61 has been going for 40 years, '78 to present.

My cylinder has the same 50ZN13 as Mikes but instead of W2 mine looks like W9. Any thoughts? Maybe its supposed to be a zero?

 

[Stump Shot]

the carb is the biggest different, that is when it went from SE to XP., xP use the 224 carb. Can it be late 85, early 86?

From what I am seeing the carburetor, gasket and spacer were updated in 1985 while still being an SE/SG. Went from 501 52 77-01 HS 163, to 501 77 79-01 HS 224. The 224 having a bigger venturi for more power.
Muffler was changed also for more power.

Thank you for your starter fix on mine.

While I made the bushing for your "older" starter, with newer pulley on a lathe, turns out Husqvarna had a bushing ready made when the new one was built to repair the old ones. Here is what they had to say:

BUSHING FOR REPAlR OF THE STARTER
In order to use the new pulley 503 10 24-01 on older design of starter with pulley post
ø 10 mm a “spare part bushing” is introduced as a spare part.
If this bushing is mounted and locked with Loctite on the pulley post, the pulley 501 52
can be replaced by 503 10 24-01.
07-01
Bushing Ref. No. 503 50 57-01

Well now we know lol. I like to think my bushing is better anyways lol.

Seeing how there are so many other W somethings on the 50zn13's, I'd assume it is a 9.
That and I've never seen a W0 on any Mahle cylinder.
I'll add the W9 to my list...

Not totally sure or not if that bushing is even still available.

Does anybody know when the 266se started and ended production?

@SawTroll could probably add to the story of the 266 SE and XP.

​

Officially, 266se production started in 1981, and ended in 1986/87 when the model was renamed 266xp.
There is some difference between an early and a late se (most notably the carb), but as far as I know there is no difference between a late se and an early xp (except the labels/decals).

I don't know for sure how long the 266xp was made, but the latest IPL I have seen was dated 1993, and the latest operators manual 1997 (production continued at the TOMOS factory in Slovenia after it was terminated in Sweden).

It is mostly a myth that the 268xp replaced the 266xp - it just happened that way on some markets, not at the factory.

Around 1987 it was fairly common that the number tag on a saw said se while the decals said xp, both on 266 and 268 saws. About the same happened both at about the same time and a bit later on other models - it was part of a general change in the model designation system, not about any specific changes to the saws.

So what is the difference between a 266xp and a 268xp?
