This 440 has had a rough life. The flippy tank was replaced with a screw tank then screw tank was baddly damaged.
Ive got lots of saws from this logging outfit. A handfull 44s a 046 and a few 66s. This one is the last one i have.
Suposebly they switched to husky and have a bunch more stihls piled up but they are a 10hr drive from me. .

Im hoping to keep this 44 and am becoming atached to it.
 
Not a good idea to hang on to rod while spinning the clutch off with a impact

Did some grinding. Spent alot of time in the lower transfers, have exhaust startex aswell as bumping uppers to the intake. Havent touched the intake yet.
Im guessing another few hours of grinding.
Intake did injest something. Theres a slight groove in cylinder and piston but it didnt go through the rings. Rings broke free wiggling by hand.
I debated ordering a piston. Hoping itl clean up fine. Exhaust side is free of20180310_194848.jpg any flaws.

Went to get a clutch and chainbrake handle and impulse bought a max flow. They just happen to have one in stock for the 440

Ohhh heres the exhaust side. Its aways from finished seems i spend as much time cleaning aluminum out of burrs as i do shapping ports
20180310_210415.jpg

I think i may have gatherd enough stuff to bolt this thing together ounce the cylinder is finished. Ive got the hd17 carb soaking over night

Ill probly wait to put the chain brake on till i dry fit a few times. Im debating bumping upper transfers alittle more and want to see where the exhaust is sitting and intake ounce i get going on it.

Was hoping to build this saw in 200 dollar ball park but ive blown that by alittle, crossing my fingers that the dang carb works. Only other carbs i have are a zama and walboro off a 66.

Been in touch with one of guys that has one of my 66s i ported. Hes interested in doing more. Im curious what i did in it, lol

These damn things are fun to build
 
Finished grinding. I dont k ow how good saw builders charge so little to port saws, ive got hours into just grinding on this one.

Finishes exhaust, finished upper transfers intake, i take always scares me because your coming into it at and angle. I had a target width and kinda accidently went passed it, with lowers and uppers worked over it should be able to use it.
Still need to grind muffler to match and im just gona open the factory port on this one. This muffler is to rusty to do much welding. I had thought about doing a cool exhaust maybe closd off the factory port and start over from scratch. Im not much for dual port mufflers i feel this hurts the backpressure effect the exspansion chambers causes. I got with a single bigger port.

Still missing some bolts and peices though very close

Well shes smoke tuned. I set the carb to 1.5 out just to be on the safe side. Had oil in case from build20180312_195802.jpg . I like to toss some oil in it.
It yanked the rope out of my hand then fired on next pull.
Will tune in the wood later.






Did just a basic hog the muffler open mod.

Seems to idle well. Looks like the gamble to not split cases may pay off for awhile.

This is the 046 carb. What jets are in it compared to the 440. Are they even diferent carbs hd17 is what this is.

Have my eye out for a top handle this one i had to straightn in my reciever hitch to get it to bolt on.

Kinda cool that its actualy coming together and maybe on the first try. I didnt know if the carb was any good even though its got new stuff in it.

Did some.e reading last night looks like a few carbs came on 44s and 46s the hd17 on both.

This morning i took the cover off just to make sure nothing bad was going on

Im missing a inner dawg if anyones got some laying around theyd sell
 
So put here in the wood today just with a 20" actualy had a tree branch blow down.

Shes alittle picky on the low adjustment. Ounce i figured out what she wanted she idles well and revs good.

Saw cuts very good in small wood doesnt bog when you lean on it. Though i think compressiin dropped alot now that its burned the oil out of bottom end.
I should have known better than to put the rings back in that were heat damaged

Caber rings will be here in a few days. Ill check compression tommorrow im almost certain its down there in 150 and below area.

Ran with stihl filter, maybe a 1/2 tank and see fines under the filter hmmm

Guess ill just have to suck it up and run the max flow ugly cover.

The 026 is out because im so rusty i had to grab it because i stuck the 20180313_204425.jpg 44020180313_204630.jpg
 
Playing with the muffler today20180314_110933.jpg 20180314_123033.jpg
Was going to order a not so rusty muffler but money getting tight.

Checked compression and its only 148ish, hoping rings bring it up to atleast 165.

Yes chain brake does work, just barely
 
Guess im posting more photos then planned. Exhaust tube is 1" with a few pie cuts to clear brake and get out the side alittle.

Did this on my tailgate. Used a carbide bur to fit the pipe. A hole saw would be much faster but offcourse i have every size but 1"

Definatly has good tone but isnt snappy like a higher compression saw. I didnt cut with it after the muffler but it does run well. Not sure its running like my last 440 though. Im leaving judgement till i get rings, crossing fingers compression climbs quite abit.

Have a few tall trees here at the house ive been meaning to turn into firewood. 026 can easily handle them but im waiting till this is up and running to its potential.alot of bucking to get to know it. Itl be fun
 
Well got caber rings installed today. And compression went up a wopping 5 lbs.
Im on the prowel for a 46 top end possibly a 46 cylinder with a 64 piston or mabe 038 piston.

Or i could big bore with 66 piston well not sure on that havent checked to see if 66 is 12mm.

This will be on going but for now even at just over 150psi its pretty strong, looking forward to cutting with it as is.
 
I never seen a 44 run a 32", would that be skip or full comp, around my parts I've never seen a saw that size run anything over 20"

Preferably Skip in Oak & stock.

Leave it @ 50mm.
 
Ive got a jb weld repair to do on my other 44 cylinder. Ive been cleaning aluminum transfer out of it. Its looking very promising.
It will be my last attemp at a 44 with higher compression. Id like to see what all the hybrid fuss is about with 46 oem and 64 piston.

Ive got enough stuff here to keep it going as for 44 for awhile.

And 32s. **** guys put them on 029s around here

I might have an inner dog..out of town, not sure. PM me to remind me to check. I'm in MT, so it'd be a free B in the mail.

Sweet looking Cummins , by the way.

I orderd a cover that cones with the smaller dawgs.
Thanks
Thats my dually i converted it to single wheel this year. Had it for 12 years

Also got a cover westcoast style.
Have her tore down again cleaned up the aluminum transferd cylinder and have jb weld curing on intake kneck. Kinda got carried away grinding. Hoping this cylinder gets better than 150.

Crystal cut the vinyl on her cutting machine thing.
 
Well the cylinder on left his tapping the piston gasketless so i put .5mm gasket in and it is making slightly better compression.
What i found interesting is it sounds much healthier both ported about the same. I took the intake a fuzz wider on it.

Im hardcore thinking about a meteor 046 top end i really want a fress piston and cylinder that blows 170 pluss

Ran into to an awesome guy thats helping make the 440/046/64 hybrid more than just a pipe dream in my head..ok actually hes the brains behind it. Im just putting the puzzle pieces together.
 
Waiting on 046 cylinder and 064 pop up piston i feel like a kid waiting on christmas. So figured id mess with muffler alittle. Give it alittle down kick kinda chopperish look.
20180322_181220.jpg 20180322_181251.jpg 20180322_181401.jpg

Im sure if the snow and rain never quits ill end up changing it again.
 
Silver cylinder is being fit first. Ive got the holes slotted to 440 now gona get it to fit in.
064 piston has a .040 popup shooting for squush at .025ish.
I think i leave transfers alone on the silver one leave timing where it is.
I think i may run right cylinder with a 046 piston or just have it as a back up
The 064 skirts are narrower. Honestly not sure what kinda porting im going to do.
Might just fit it all together and see how it runs then go from there.

20180324_231643.jpg

Excited to see here come to life. The 44 cylinders i have are tired, these 46 cylinders are in very good shape

Thank you bigblue for all the help, hes responsible for 064 pop up piston and answering lots of randamn questions 20180324_232552.jpg
