Thanks to Spike60, a fellow named "Matt" and the local parts barn.. a new project is forming ...another a box of parts to a saw blending project. 268, 266 (old style ), 272 & a bunch 630 and 670 parts...maybe a red & orange blend? Can a 630 Jonsered run like a 272? Or maybe a 268 open port cylinder be made to run like a 272XP? Maybe additional finger ports to even the playing field? Time will tell. Haven't picked the final direction just yet.

Have two good top ends...a 272 and 268 open port...3 good bottom ends & a bunch of details...only missing top covers...have some red (black) cover/filter combo's that should work just fine. I'm a piston shy of having another 268 top end. So....first task to piece together a running saw...272 or 268? Hummm..

Sounds interesting .To tell the truth though my knowledge of Husqvarnas would fit in a thimble so I have no idea what would fit what . Macs yes and some Stihls but that's where it ends .

Just keep building more saws; we don't have enough yet. ;D I like the idea of a Red/Orange halfbreed. One of a kind saws like your 272 white top are pretty interesting. I'm going to have fun with those 254's. I'll keep one stock, and experiment with the other a bit.

Sunday was a fun project day, and I think I sent you home more junk than you brought down, at least measured by weight.

One of the upcoming GTG's will have to focus on saws that we brought back from the dead and built ourselves.

I have a faded but decent 266 top cover I can add to the box if you like.  I'm even up, or maybe 1 short on coils and chainbrakes, but I have a bunch of odds and ends if you're missing anything. 

If one of y'all run upon an extra 268/272 coil or two, I could use one to replace that green coil on my Poulan Pro 505.
I don't try to explain to others why I play with chainsaws.  For those who already know, no explanation is needed.  For those who do not, no explanation is POSSIBLE!

I may have a spare coils, I just don't know how good they are. So I will drop one in that red box. You have enough to stick together a 266 or 268? Maybe I can fill in the gaps there for you as well. Have yet another project saw based on that series. I have a 266 set of cases setup up for the old style 266 cover with the different mounting screw locations and two coil ignition..its crank or crank bearings are bad. I also have a 266 cover...was thinking of the custom concept like with that 61 I did before...maybe a 266 to 272? Was leaning towards a 630 to 272 blend if I can find enough red plastic...of course this snow may force an orange saw as all the red is snowed in in a big way right now.

Is this a bolt in without having to re-time the flywheel?

My 415 had the unlimited coil, but I havent checked the 475 yet. It's down on the list.

The Poulan 475 yellow, right now looks like it is going to get a red Jonsered 2077 tank.  :o

My 362xp has some red Jonsered in it too.  :D Then you the red-yellow 490-5000 hybrids  ;).

I have several of those partial saws around.  There are a few bottom ends, but nothing I think is worth trying to build a saw from.  I do have a pair of complete dark-top 61's that are set aside for refurb.  One is locked up, and the other is free but low on compression.  I have not spun the free one fast enough to test the ignition.  Obviously the stuck one has not been tested either.  I think I have a spare two piece ignition though.  Those saws are going to be a little experiment for me.  I have a closed-port 50mm 268xp jug and a closed-port 50mm 266xp slated for them.  Rumor has always been that the 268 cylinder is better.  I am not so sure.  I want to set them up stock and run them side by side.  Then I hope to crank up the compression and have another look.  That is long term, and those saws are not taking up much space.  I'll get to it one day. 

Single place coil would be appreciated if you can spare any.  Rev limiter on that 505 (J-red 2083) is pretty annoying.

I am sure you know this, but others may not - the 2077 and the PP 475 both are the Partner P7700 in different colors. Add to that, all the saws probably were made at the Husky factory, but there was no Husky version!   8) 8)

The sorting begins...i've had that "bright" orange 268 bottom end around for a while...and this influx of parts will be what I need to make it into a runner. That new 272 cover also may go over to my other 272 and the rougher one come back here to this project...


So here is the final selection to pick thru from the boxes:


I think its an interesting contrast between the open port 268 and the closed port 272...so here is a side by side pic of the two designs..268 open "finger" port cylinder & piston on the left, 272 closed port on the right:



I put some time this weekend into this 268 combo..its been assembled with stock gasket augmented with Three Bond 1194 and a new carb kit. The filter came from a J-red pile I have here and this older style allows a low top cover....I like them better as they feel less clumsy to me. A minor thing.

The "Mockup" 268 top end...




So the goal for the day (or tomorrow depending on snow accumulations) will be to get a running 268 open port saw together. Then start hacking because we can. Just want to start with a runner to take debugging variables away as we proceed...towards the third "Chopper Saw" in the collection.....

Put together a completely stock 268 as a starting point. (And yes it runs Bob..:)...the piston had a collapsed skirt)

A couple of things to look for when your dealing with a bunch of parts saws...one is the oil pump/case seal. These need to be looked over and really its worth popping in a new seal and "o-ring" to ensure a good crank case seal on this PTO side. Also make certain the oil line & oil pump aren't clogged. Following is a few pics of a bad set of seals & clogged oil pump to give you something to see that's not atypical actually on saws sitting around for too long ...especially on concrete floors.

Pulled the pump and here is the oil line...make certain the "sealing' surface on the top is good or it won't seal against the oil pump.



Note the mating surface to the rubber oil line on the upper right of both oil pumps..one good one bad....the one of the right is both clogged and corroded..don't thing this oil pump will ever work...just stuff to look for!



Same with the "o-ring" and inner seal on this oil pump ...the one on the left has a brittle & broken "O-ring" and worn seal...those seals are cheap..just replace them regardless!



Anyway...did all that and stuck together the parts to make a running 268 with a 272 cover...a starting point for the project. This will be the comparison saw. Going to build a lightly modded 268 next I think...then run them side by side to see if those changed were worth the effort...then a J-red 630 Bottom & plastic with 272XP top end..If i can make it for for the next "Chopper saw"..right along side that 61/272 Chopper. That's the direction this project will wander..unless input from you folks push it another way..

To review..this was built with the "open port" 268 cylinder & filter shown in the "mock up top end" photo and "comparison photo" in the prior posting. Used Three Bond & stock gaskets everywhere there was a gasket...on the stock saw...




Nice running saw...cuts wood...the first saw to form from the junk pile...:)

At some point i want to build a true Husqred. Crank case half red and half orange. I have seen it done, but have read it is not advised as case halves should be a matched set.

I agree and that's what i would do if my road to where the Jred parts stash wasn't under 8 ft of snow! I have a pair of 630 old style cases/bottom ends...:)

Might have to work on that other two stroke engine powered machine to get parts for the project! Or sled down the hill and hike(snowshoe) back!

K...was able to piece together a running 268 and running 272 from these parts. So now project time. They both are pretty ugly!! So Either to clean up, muffler mod, and do some mild port work or build a J-red 630 blend with the other....or stretch and build yet another out of a 630 J-red....and a 272XP after market jug I have...hummm Decision time...or if there are any other ideas out there?

Got the old Snowmobile running! Still probably needs a carb kit as some point. Fired right up...on the old gas too! It was a Mobile One MX2T blend so it had sabilisers maybe thats why it didn't go terribly bad yet...new mix is in now.

So 2 morrow off to the woods to collect parts for this project.

Also a couple of details...stuck together a 272XP out of that pile so there is both a running and complete 268 and 272 now. Both are ugly as sin..but this is a good place to start.

272 ugly saw..:


WHen blending parts another small anomaly turned up...pull start assemblies. The older ones were not as thick as the newer 272's so the pully's don't interchange I put up a picture to show the difference;

Pully's  the 272 is longer (on the left) 61 is on the right. I put a 61 pull start guts in the 272 cover..didn't work. So had to go back and put the 272 puller in.

Finally got back to this Chicken Chit to Chicken Soup set of saws. Have a running 268 based saw and a running 272 out of the mix. So starting with the 272, the plan to to build it into a functional reliable saw with a few tweaks...and try out a few mod idea's along the way..so first was to do a low buck and hand tools only muffler mod. Not every one has torches! Pics tell the story..its ugly but helps the saw make more noise!


This saw did get a new aftermarket chain brake/clutch cover. Have to be safe! This one was a Forester brand but there are others. AND those little rubber sqwrench holders are really handy. Most of my saw I carry in the woods ends up with one. Bailey's is where this one came from.



No I didn't grind it on the saw! Pulled it off, drilled out what I could and used a die grinder to clean it up before putting it back on the saw. Just hogged out that stock restriction hole ... BUT leave a little on that front side, where I'm pointing with the die grinder, so there isn't a straight shot right to the chain brake handle! Have to be certain you leave enough so the deflection cover can keep the exhaust gasses off the handle.



Opened up the deflection cover with a pair of plyers...was looking to end up 80 or 90 percent of the cross sectional area of the exhaust port...but I made it a little more because of some things coming to this saw as I have time..:)



Bolted back on for now...



It still deflects away from the chainbrake as the stock configuration did...after some testing I'll  decide if this is a workable mod..and if it is, paint will follow..if not; i will cover that hole and do my standard muffler mod on the 272's with a 3/4 inch steel tubing for the outlet.

Any predictions?

(I think I should rename this thread..cheap work saws! Or Chicken Chit to Chicken soup saws...the idea being you can have fun with junkers from a variety of sources if the dollars are tight.)

And its beginning to evolve into the higher evolution "red" form...my bet is before this year is out that evolution will be complete!
