My new(ish) saw

[Big A]

Got this little baby for myself for Xmas!!:D What I want to know is how to determine her age? Oh and what fuel mix ratio would they run on?

[JamesTX]

Port the serial number - I bet Chisel Tooth could helpyou.

[GASoline71]

With modern 2-stroke synthetic oils (Stihl Ultra) you can run 50:1 if you want...

40:1 would be good.

Gary

[Big A]

Cheers Gary, I did think it would be ok, but just wanted to hear someone else say it!!:D

[Stumper]

James, Sooo.... If Andy ports the serial number will he get higher torque output?:P


Andy, The oils are better now---you can run anything on 32/1 even the old Macs that specified 10/1.

[GASoline71]

I am running Stihl Ultra in all my saws at 50:1... even the old Homelites and McCullochs I have from the 60's. No problems at all...

I saw that too Justin... I never have ported a serial number... I wonder if Ed Heard does that? :P

Oh yeah... sweet saw Andy! :thumbup:

Gary

[Stumper]

Gary, I don't doubt that 50/1 would work okay...but I'm just a little lubrication happy so I stick with 32/1.

[Big A]

Port the serial number - I bet Chisel Tooth could helpyou.

I'll take a look tomorrow, or will it need carbon dating?? :D

[GASoline71]

Gary, I don't doubt that 50/1 would work okay...but I'm just a little lubrication happy so I stick with 32/1.

True Justin... but there is a thing as too much oil... Especially in the more modern saws and OPE...

Andy... are you gonna restore this monster? Or just play around with it? :)

Gary

[Big A]

I bought her as the powerhead for an Alaskan sawmill, so she'll get a new bar and chain. gonna test run her tomorrow, see how she goes, then Monday going to run her at a Douggie fir butt that I felled earlier in the year. Then, if she's running sweet, buy the mill attachment. I got her mainly for demos at shows, and a bit of hobby planking.

[GASoline71]

Awesome Andy... that will be a cool milling saw... Take pics when you rip into that Doug! :thumbup:

Gary

[sotc]

wht size/model is it?

[Big A]

She is a Stihl 090......137cc I think

[Big A]

Awesome Andy... that will be a cool milling saw... Take pics when you rip into that Doug! :thumbup:

Gary

Just gonna cut some biscuits Monday, just to get a feel for her, then after Xmas order up the Alaskan.

[Chisel Tooth]

Looks like a 08S introduced in 1965, 56ccm, 7000 RPM. The recommended mix is 20:1 using Castrol 2 stroke SAE 40. But like the guys said with the new oils out there today you shouldn't have any trouble. I have a old Mac 650 that I have ran Stihl oil at 50:1 in for over 12 years with no problems at all. Nice find. Let me know if you need anything for her.
See Ya
Mike

[Chisel Tooth]

Sorry Andy I'm wrong, the top cover is different from the 08S, it is a S10, 1968, 56ccm, how ever the early models were 46ccm. Everything is the same as posted before. I don't have one of these, and I'm still looking.
See Ya
Mike

[GASoline71]

I don't think that is an S10 Mike... My uncle has an S10 and it don't look nothin' like that saw.

Gary

[Skwerl]

The most important thing when determining mix ratios is the level of lubrication. If you're going to mix 1970's era 40wt oil with your gas then you need to mix it at the ratios specified back then for that type of oil. If you're using modern synthetic mix oils then you will get superior lubrication by sticking with the current recommended ratios of 50-1 or even 40-1 for large displacement saws over 100cc.

That answer will still apply regardless of the saw in question. :D

[GASoline71]

Good post Brian! :thumbup:

Gary

[pantheraba]

That is a neat looking old saw...looking forward to seeing it in action.

[Chisel Tooth]

Again I'm wrong, I did some looking and again the top cover is different. Everything else looks like the 08, 08S, and the S10, except the top cover ain't right. This is the S10.

[Big A]

Where would I find the serial no.? cant see it in the usual (modern) places. Inside the air filter cover it says 091 model, but isnt this a cut-off saw?

[Big A]

The bar wth it is 404, 27" long, looks tiny on it

[Big A]

Cheers Chisel, thats the one!! I know my pics dont do her justice, and she's done a bit of work, but she'll do, hell I'm tired and she's 4 years younger than me!!

[Chisel Tooth]

Ok I slowed down and did some looking ,it is a 090.
1968, 137ccm, 13hp@6.500 RPMs. 20:1 as before.

[Big A]

Any idea on spares availability? I know there's a few of these about in this country, but nice to know where I can find bits if and when I need them.

[Thor's Hammer]

cool saw andy. where did that pop up, and how many bones?

[GASoline71]

I think that you can find parts on ebay quite often...

Bailey's sells aftermarket parts for the 090... but not sure about gettin' them shipped to the UK.

[Big A]

Found her languishing in the deepest darkest depths of Ebay last week, paid £499 plus p&p for her. see theres some on there again this week!

[High Scale]

Try Carr's Andy in Bristol, they should be able to help, they bought one of those of a old boss of mine I believe.

[Big A]

Cheers Carl, thats handy! Cant wait for the morning to fire her up now! Sure the neighbours wont mind!!:)

[Chisel Tooth]

I think you would have a better source of parts over there. There are a few still around over here, and as I understand it this model is still sold in Central America.
See Ya
Mike

[JohnB]

I would think they'd be available in Germany?

[JamesTX]

James, Sooo.... If Andy ports the serial number will he get higher torque output?:P


Andy, The oils are better now---you can run anything on 32/1 even the old Macs that specified 10/1.


Any one can port a serial number - but you get the best results when you use a number cruncher CPA.

[Big A]

:D She's a good 'un!! Woo-hoo!! Runs like a dream!

[High Scale]

Nice one, pleased for you.

[Big A]

heres some pics forwarded by the previous owner, clearing trees for their off-roading out in Australia. Cheers Alex.

[Al Smith]

I have a old Mac 650 that I have ran Stihl oil at 50:1 in for over 12 years with no problems at all. know if you need
See Ya
Mike I've got a thundering old 650 too but being somewhat like Stumper I prefer 32 to 1 also.It only smokes when you first start it up ,due to a bit of oil sucked in by the impulse oil pump,old ya know.

I imagine 40 or 50 to one would work fine but I tell you now old habits die hard.I used to wonder why in the world some of the old timers were so set in their ways.Now I am one and I still don't know.:)

[Chisel Tooth]

With the additives they put in the oils these days, I don't see any problems running them in the older saws. I think it all comes down to what you are comfortable running. I know one fella that refuses to run anything but 16:1 in all his older saws.
See Ya
Mike

[GASoline71]

I agree Mike... I guess the day I actually do have an oil related failure, maybe I'll change my tune. Until then it's 50:1 Stihl synthetic in everything.

Gary

[RIVERRAT]

Gary
You run saws & "PLAY" with them long enough the chances are you will have such a failure. A lot of things happen as a saw ages.

I just believe a well seasoned ear & a little more oil gives an aged hand a little more time to shut things down before the carnage starts.

[Chisel Tooth]

I would agree Jeff, you run anything long enough you will see ware. On the other hand I would equate the amount of ware to the quality of oil and not the amount. The oils today are Formulated for the higher RPM, and the higher temperatures of todays saw. The saw today run at around 13,000 RPMs and can have ringland temps reaching 300 to 400 degrees. Where the older saws tend to run 6,500 to 8,000 RPMs, and have much lower temps. The debate is still open, but for people that use their saws everyday to make their living, why take a chance. Until proven other wise, go with what is shown to work.

What is diffrent in 070 and 090?

If I remember correct dissplacement or at very least bore needs to be messured to be sure... But again.. These are far from what I coulod call in my interest...

Could this not be a 070?


Oh, The 08 and S10 is much the same in the top handle version. 08 has HL and S10 has HS carb if I am not misstaken...

I agree as well as Gary - I believe you both are right! :) ;)

The oil is the issue, not the age of the saw - at least when it has a Nikasil cylinder.

[Big A]

090 serial no: 1210939. Trying to find out if its the 090 or the 090G.

[Chisel Tooth]

Here are some pics of a 090G, the G stands for gear drive.

[gf beranek]

It's an 090, alright. Want to do some milling with it? Oh, Baby! You wont have any feeling left by the end of the day.

[Big A]

Haha the milling thing is gonna be a hobby/dem sorta thing, not an everyday thing. Hear what your sayig tho. Hats off to those who've worked a full day with one off these saws! Thanks for the pics of the G model, just wanted to clear that up.

[Big A]

Ok after much delay and hassle finding the right bar,(Stihl sent out an 088 bar in error) here she is with a 36" lasertip. Run up and raring to go, got a Beech takedown tomorrow, where she'll be a back up for the 066 & then the Alaskan Mill is on order.

[MasterBlaster]

Beautiful!

[Burnham]

Sweet, Andy. Very sweet.:thumbup:

[Big A]

just a bit annoyed with Stihl, they no longer sell bars (in the UK anyway) for this saw, yet still sent an 088 bar, wtf. The Oregon bar cost £88+vat, a 4foot bar comes in at £235+vat!! Oh well 3foot it'll have to be for now!

Brutal, when I learned to climb working for my father an 090 was in the regular lineup. Big Cottonwoods with a 48" bar knocking down wood. It is all you can do to hang on.

[sotc]

lookin good, i gotta get a 4 foot bar one of these days

[Al Smith]

An 090 has plenty of grunt,no doubt.

This bar issue comes up all the time.It really is not that hard to retrofit one mount of bar for another.I've done a bunch of them myself and it really is not that big of a deal.

The 4 foot bar on the Homey in my avatar is actually a hardnose Mac mount bar.The other bar for that saw is an 084/088 Stihl mount,3 footer .Both bars can fit both the big Homelite as well as the large Macs .The 3 footer of course would bolt right up to an 084.

[olyman]

and that saw--is a carbon copy of mine---why--because the exact same fin is missing on the recoil housing!!!!!!!!!!!!! and i repainted it---

Hmmm any ideas whether there are similarities between the 090 Stihls and the other makes, for bars to match up? Big (old) saws over here seem to be few and far between these days

[Al Smith]

Hmmm any ideas whether there are similarities between the 090 Stihls and the other makes, for bars to match up? Big (old) saws over here seem to be few and far between these days I've never actually seen an 090 mount pattern.I have been told however that with minor differences they are close to the 084/088 mount.

If I'm not mistaken,Mike Acres web site shows a majority of the different mounts.

Just as an example,I pick up a large Stihl mount,Winser bar,36" plus a new loop of square ground chisel for around 45 bucks from e-bay.I turned a set of bushings to simulate the bosses used on Stihl bar studs and did just minimal work on the adjustment and oil hole to use this bar on both the large Homelite and Mac saws.

If I'm not mistaken the large Stihl mount bars use a 14mm slot .If you attempted to refit a Mac or Homelite bar,the slot would have to be milled out which would be not only costly but a pain in the butt to do.Besides that Stihl bars are much easier to find than the other ones.

Spitting chips with the 066

if i could work out how to convert a MP4 file to MP3 i could show you that the beast lives!

we have an 090 in the workshop. its not been run for a year now. purrs away nicely when it does run. we run a 4 foot bar on it.

Was the chain dull?

[Big A]

Was the chain dull?

Brand new bar and chain, however I think once the files been run over it a couple of times it'll be better.

[stehansen]

The video was really choppy for me. I couldn't tell how he was doing.

[Al Smith]

That is about typical of an 090 .These things have an air vain governer that keep the rpm's down .Powerfull,not lightning fast.

The old ones you hear so much about in the saw races had been highly doctored on. I have been told that even a souped up only kicked em over at about 9,000 rpms,more or less.

According to my Stihl micro fiche the max HP of an 090 is 8.5 taken at 7,000 rpms.Max torgue is at 5,000 max permisable speed ,8000 .

[Big A]

Thinking about the 066, Tim hit some copper when cutting off the top chunk off the stump, we'd re-sharpened the saw, but the 090 was cutting a curve with a perfectly straight bar and brand new chain?!? I even double-checked the bar today when I stripped it down to make sure I hadnt bent it somehow.

[Big A]

cheers for that Al, I'll get it tachoed tomorrow sometime, just to double check everything is set right.

[Al Smith]

Seemed rather timely ,I leeched a picture of the 090 mount from one for sale on e-bay.The seller said it would fit the 075/076 ,084/088 and the 090.

[Big A]

thats right, the 090 bar will fit the 088 et al, as the mounting holes nearest the sprocket are correct, but an 088 bar doesnt have the forward holes, or oiling holes forward either.

[Poleframer]

Seemed rather timely ,I leeched a picture of the 090 mount from one for sale on e-bay.The seller said it would fit the 075/076 ,084/088 and the 090.
Yep, notice the double adjuster holes (one was added). All you need to do to mount a 088 bar on a 090 is drill new adjuster holes, the oiler works fine with the existing oil holes (I mill with one). 090s run slower, but about when newer saws start doggin, 090s are just digging in.

[Big A]

When I tried the Stihl Rollamatic bar, the oil hole was nowhere near the oil feed, I did consider drilling it out, but was wary of doing so, (not the best mechanic on the block) so returned it and swapped for the Oregon Lasertip.
Set the tacho on it today, she was revving at 6250rpm, now set to 6750rpm, midway between the two recommendations.

[Big A]

Since the price of 090's has hit the stratosphere most other large saws are following suit .

That one is listed by Rich Dougan[Sawking] I have no idea how he finds so many old large saws but he must have cornered the market in the PNW.

[Big A]

Ok, so finally got the old girl fitted up with a Alaskan mill, made up an auto-oiler mounted on the mill, (as she is manual oiler), and been out milling, checking it out for glitches. Back home, had to fit a shear pin into the oiler hole I drilled on the tip-end, to control direction of flow into the hole. The vibes kept shaking the oil pipe away from the feedhole. Sooooo now she's up, running and pulls like a train!! :D
And the best bit was when Blue rang me while I was milling, so I just answered the phone, and dropped it by the saw at full revs, gave him a good earfull of Stihl Power :evil:

I didnt think to time it Carl, but now you've raised it I'm gonna have to see. I know it seemed to cut like a knife thru butter tho, but it is Thuja, I just wanted to see how it all ran.

[sotc]

sweet, im gonna pick up my alaska mill today, my dealer said they do oil by themselves, the manual oiler is for extra oil. told me i didnt need the extra oiler so i opted out.

[Big A]

Yeah, but mine is an old 090, manual oil button, on the right hand side of the handle, so its a pig to operate when milling, hence the oiler feeding the chain.

[sotc]

sounds just like the one i have

[rumination]

Awesome, Andy! Alaskan milling is fun.

Willie, if you're going to be using a long bar for milling I strongly recommend rigging up an auxiliary oiler.

[sotc]

36 inch, they didnt think id need it but did say to try it out. i sure dont want to be pumping on that lousy thing!

[Big A]

I made my aux oiler up out of an old lawn mower fuel tank, a length of pipe and let good old gravity do its work. Simple and efficient. Dunno what they cost in $$$'s there, but £40 over here!! :(

[sotc]

good thinking!

[Big A]

the old 090 and 660, sweet!!

[sotc]

looks like a tank next to that sleek 660

[Big A]

I'm thinking of importing (from the US) a decent length bar for the ol 090. Can anyone comment on the Woodsman Pro bars? Seeing as these are an unknown in the UK. Looking for a 4-5foot bar, anyone got a good secondhand I can make a deal on? Must run .404 chain. :D
