Think a new project beginning to shape up....some blend of 268/272 stuff...

[weimedog]

I like it better as well...the filter was in the "Junk pile" I guess 272's came that way. AND BTW that saw went thru a major transformation today...

Up to this point, other than the "Red Neck" muffler mod, the 272 "CS2CS"  (Chicken Chit 2 Chicken Soup) has been stock and assembled with all the stock gaskets. It's been put to the noodles test and has a fair amount of cut time is long cuts....a reliable saw. But boring.

SO.. I resurrected a toasted After Market 272XP cylinder that had died a "wolfs head" 10w40 motor in 5 year old gas death! So it was cleaned up and ground on with a die grinder & carbide tool to get to where you see it in these pictures. A practiced eye will see immediately the several differences from the OEM cylinder that came off. (The OEM cylinder is going to visit an ultra sound cleaning tank and after a bath get introduced to a brand new OEM piston....and will go on which ever of the modded CS2CS saws that dies first! Oh...and i also did a more radical mod on a open port 268 CS2CS..but want to run it for a while before I embarrass myself online with pictures of it....they will come later..if it actually run well. It got carb mods, some port timing changes, and a muffler mod my typical pipe way. Really curious how that 268 CS2CS goes relative to this 272Xp CS2CS!)


.I'll post pics along with some tips to quickly change cylinders on that series of saw..I've got it down to 1/2 to swap cylinders on that one.

Here goes....some pics relative to the 272XP-CS2CS!

[weimedog]

Pulled the standard 272XP Cylinder off and put a mildly modded one on..just to see if the grinding bears some performance fruit..


A peek at the exhaust port Widened and Chamfered...that's really it. Also matched the exit to the "Red Neck" modded muffler.



Transfers


Intake..(Widened a little but not past the piston skirts internally)


Exhaust...also widened internally a bit..nothing radical!

[weimedog]

Also cut the extra length of the screws holding both the throttle plate and choke plates off...(hope it doesn't get sucked into the motor!!!)

[weimedog]

Some assembly tips:


I assemble the intake right to the cylinder so there is a better seal between all the components...also easier to do when everything is accessible!



Then I rotate the crank so the piston is in effectively TDC position..furthest out. Then I stuff a screw driver in the flywheel to hold it there, put my 1194 on the case & cylinder base and last but not least put on the ring compressor.




Just slide on the cylinder/intake assembly....(Remember, I'm a one man show; so there are no extra set of hands!)


Remove the screw driver and ring compressor (rotate it so you can pull it out the front side after the cylinder is over the rings on the piston)  and seat the cylinder in the case..that's it.

[weimedog]

Couple of other things...

1) It is SO much easier to just pull off the covers and handle bar to get at stuff.
2) I used the Red neck muffler mod I had posted a while back...and I usually fill the muffler flange with brass (brazed on) and then file flat to get a really good seal...expecially on those old bent up mufflers!
3) Tip the saw on its side to start the cylinder screws!!1

[weimedog]

Today they both get "noodle" tested...on 2-3ft dia hard maple. They either thrive or cook!

See if you can find a part number on that filter we are talking about. 

[drilldog]

pretty new to the forum & dont get much time to enjoy it with working out of town & all. i was reading about your air filter & it happens that my saw guy has a couple of NOS K&N filter set ups. I run one on my Husky 61 with a muffler mod. they were made by performance connection & come with a blue cover. (add some more color to that Husqred). if you would like i can get some pics of it posted. just a thought, thanks.

WD, I found all the part numbers to put the hd filter set up which was for 268 too and posted them in my husqvarna 268xp 272 thread at chainsawrepair.  

[weimedog]

So a year later how did those saws turn out? I put a summer on the 272 and its now over at my Brother In Laws...solid performing saw. The surprise was this 268 open port. Its was slightly modded, opened transfers & exhaust,  tweaked intake as well. It runs easily as well as the 272 with a livelier feel to it....and almost 40 tree over the last month have really put it to the test..its still building compression and just runs better every outing..




Hauling another log cut by that little 268

[weimedog]

Second truck load of tree's primarily cut, limbed, and bucked with that 268 open port project.

[Al_Smith]

 I detect a dead ash or two there .Fact being I've been cutting them since summer myself .

[Clam77]

Ahh - the ash borer problem... I have pics of a town up in the USPNW that had to cut them all down - many of them alot bigger than what WD has posted here.  The town made it into a competition to make chainsaw sculptures with all the stumps over town.  Good pics but sad really.

[Al_Smith]

Total removal is about the only option on those dead ash because given enough time they will go over on their own gravity being what it is .

Those urban yard trees are iffy but the woodsy type sure make good lumber and  you'd just as well get them before they degrade .

Fact being in my little case on only about 3-4 acres of woods I'll end up with over 10,000 Bd ft of saw logs before they're all down .

As far as selling them ,the mills will take them but being that type business they won't give much for them so sadly to say they're worth more as firewood .

[weimedog]

Actually there is no dead ash in any of those loads. The bug hasn't made it here just yet but I guess its inevitable. I have a lot of very high quality tree's on the farm that I decided to take down so I don't loose the value over the next couple of years. Probably have another 50 to 100 trees from what I found yesterday along in the wet area's that are larger then 24inches... Headed out right now to pull some while things are frozen.

Walt I've said it before your place is like a playground for saw nuts.

I see where some of my fellow NYers have been hiding out.

I came across this thread because I'm looking for experienced advice on rebuilding my 1985 Husky 61.
I want to thank weimedog for his time and efforts in documenting his work on this build. His inclusion of photos is much appreciated - They answered much of my new-guy guesswork.
Thanks!

[weimedog]

Thank you.....also did a thread I think on blending a 272XP to a 1978 "old style" 61..

[ComputerUser]

Nice thread!  More pics of the saws at work would be icing on the cake...and I do like icing...
