Title: Husqvarna 66
Post by: Cut4fun on March 01, 2011, 02:30:06 pm
I just took this husky 66 in trade. What can you tell me about them? So far a missing carb what carb was on them?

I have never dealt with this model and closes thing I had was a 266xp I traded for and then traded off because I learned no parts interchanged with my 2 262  :-[.

We had them for a year or two. They were one tough saw. If I remember correctly they were open port. Been a few years though so may be wrong.

Pretty sure I have a 66 carb here.  I bought a parts saw for the ignition and stripped it down.  Not alot of 66's around.  The gillardoni cylinder on mine was of VERY nice quality.  It is an open port 50mm bore.  Are you missing the entire intake, or just the carb?

Havent got that far yet. Sorry.  Just a glancing look under cover while going to shelf.

I noticed this one has metal brake handle and the one on Mike Acres site has plastic handle ??

The 66 was only on the market for a short time. Maybe 2 to 4 years??? I think they were all gray top saws. The switch from the metal to plastic chain brake handle on many Huskies took place during that time frame.

The 66 uses the same open port P&C that was later used on the non-XP 268, as well as on the 268K construction saw. (The jug in the box looks like it's from a 372)

 Don't see many of them, as it's a pretty rare model.

The IPLs go from 1987-06 to 1991-02, but that isn't exact info on the production time.

Regarding the carb, the one listed in all the IPLs was the HS224A.

I got a HS260 off a 272 laying somewhere on a shelf. I wonder  :-\

The other saws that used the HS224 was the 266SE from about 1985 and later the XP , the HS 260 was used on the differernt 268s and the 272xp - so I guess it isn't a direct fit.....
Title: Re: Husqvarna 66
Post by: Cut4fun . on March 07, 2011, 06:04:58 pm
Does the HS224 on the 66 have idle screw built onto carb like the HS260 carb or is idle screw on the saws body itself and reaches over to carb to adjust linkage that way?
Title: Re: Husqvarna 66
Post by: SawTroll on March 07, 2011, 06:19:00 pm
I don't know that - I am not a tech, I just happen to have collected some info, out of general interest.

If memory serves, I believe the 66 used the same jug as the later 268 open-port, btw - but not the same carb.

I'll go look up the carb IPL and I will be able to tell.  Thanks Niko for help.  8)

I found both style HS carbs here.

Was looking the 66 over today. the top end looking through the spark plug hole looks brand new. Pulls 160 psi.  Has a Gilardoni 2 cylinder.

This part loses me. On the tag Tomos yugoslavia   ???

Got a HS224 with no choke or choke lever. Using a squirt bottle with mix to fire off. 

I have a Tilley 218 with choke set up, wonder if it is the same as used on the 224 carb?

Saw Troll could fill you in on the non Swedish Huskys. Our last run of 266's here in Eastern Canada were from there also. Had a mint one that I regret letting go.
Title: Re: Husqvarna 66
Post by: SawTroll on March 21, 2011, 06:54:02 am
The 66 is one of the Husky models that was made at the Tomos factory, as part of a political deal initiated by late Prime Minister Olof Palme (yes that infamous one) in the 1970s. Late 65s and late 266xps also were made there, and more...

The usual rules regarding the black vs. "silver" number tags don't apply to those saws.

The later ones are marked "Slovenia" instead of "Yugoslavia", for obvious reasons.....

1987 - 1991 what the IPLs indicate - but they may have been made later than that by TOMOS.

The first IPL to show the plastic brake handle is the 1989-02 one.

The one in the pictures looks like a TOMOS made one, based on how the number plate looks.

Forgot to say; I do not know when production was moved to the TOMOS factory, or if there was any "overlap".

The same is the case with the 266xp.

I have a cylinder,and the intake port is much smaller than my 266se

No clue here. Never pulled the open port cylinder. Went straight to a collector overseas somewhere.  Thinking it was Finland. Cant recall for sure now.

Post by: Spike60 on June 19, 2020, 05:49:02 am
Intake port really shouldn't be smaller than a 266. Actually ought to be bigger. That 66 top end is the same as used on the 268 open port and 268K cut off saws. Uses the same intake block as the 268/272. Possible that different cylinder sources could be the deal. Gilardoni maybe? My 66 is from the Tomos factory, and I've never taken mine apart either.

Post by: Cut4fun . on May 29, 2022, 07:59:33 am
Corey compared the 66 and 268 open port. = I always thought the Tomas built 66 used the same Gilardoni topend as the 268 non xp, they are in fact different, same 50mm open port but the 66 uses the older 266 style intake design and more laid back spark plug. same piston used in both. Just throwing the info out there.

Title: Re: Husqvarna 66
Post by: Spike60 on June 03, 2022, 07:19:04 am
Hmmm. Have to take a closer look at mine and see what I have there. Don't want to pull it apart, but I guess we need to do a little more research here. :)
Title: Re: Husqvarna 66
Post by: Spike60 on June 03, 2022, 09:52:13 am
OK, mystery solved. The 66 was actually made with both of the cylinders in question! There is a service bulletin from Jan 1991 that announces the change to the 268K top end. It also lists all of the necessary intake parts. Entering either of the original cylinder numbers supersedes to the current 268K replacement item. The cylinder has the same 5036111 casting number, but is now produced in Brazil by Kolbenschmidt, and has the "KS" emblem cast on the other side.

Wow nice and Thanks for time and info. 

Shared with Corey. He collects saws. He is trying to do every year of the 266 for one. He has bought 3 of them from me already. Has to be years he is missing.  Thats another saw That had alot of changing I noticed.

Well, I took a quick look at my 66. Has the 4 bolt intake so it's the early P&C on my saw. Not curious enough to pull it off and check it out, but from what we've got going here it looks like the early 66's use a top end that is unique to those first few years that isn't shared with any other model. (And no Jonsered version either.) Makes it a little more interesting from a collector standpoint. And a reason to give it a workout on the wood pile. At some point this summer I'll pull mine out and run it along with my 1992 268OP.
Title: Re: Husqvarna 66
Post by: Cut4fun . on June 05, 2022, 07:46:02 am
Yep Corey is going to compare his open ports too in the wood now.

Thanks for all the background work for info.

Honestly, I have fun digging through the old docs and finding answers to some of these riddles. Have a lot of stuff on paper, but that SB wasn't one of them. Dealers have access to a lot of stuff that I don't think is available on the consumer site. I can log into "service documents" and then the format is "SB, 66" as used in this case. Another example would be "IPL, 242" or "WM, 2100". WM is workshop manual, and OM would be owners manual. It's pretty much all in there. Problem is that we're winding down the store to retirement at the end of the year, so I'll lose the ability to do research like this. I've got most of it in books, (or in my head), but like we're seeing here, there's a ton of things that need looking up. Assumptions or filling in the blanks with our imaginations doesn't work too good. :)

Guess what I should do is spend some time pulling up the electronic versions of the old docs and printing off some of them and adding it to these old musty binders I have.
