Title: differences between 026 & 026 pro?
Post by: Vance in AK on August 15, 2012, 02:49:37 pm
Hey guys.
New to the forum & 1st post.
Was in a saw shop yesterday looking for some Jonsered parts & the guy couldn't help me.
BUT (famous last words) he had a nice clean looking little 026.  Almost new 20"  (May be 22", can't remember) Oregon rollernose bar & 3/8 chisel chain.  Shop took it in for repair & it was never picked up so unknown history.  Price was $175.  Sounded fair & I've been thinking about a smaller saw since I'm getting older & the part of Alaska I'm in doesn't really call for 30" bars for firewood cutting so I grabbed it.  Was that a fair price?  Got it home & cut a couple of rounds of spruce about 16" in dia & it runs & cuts like a champ.
My main questions are what's the difference between the standard 026 & the pro (besides comp release), & any particular problems to watch for on these saws?  Couple of friends have Farm Boss'.  How does the 026 compare?  Is a 24" bar a little much for these saws or will they generally handle it OK?
Back in the late 70s-80s I spent a lot of time working in the woods & running 041s on landings & 045 etc bucking, but not familiar with the newer Stihl stuff.
Thanks

Welcome to the site.  8)

026 and 026 pro. I think differences is pro has adjustable oiler and de-comp.   

Maybe someone else will chime in if more differences.

IMO 20" would be my max on the 026.

Me personally  would run a 16" for the cc size saw, thats just me.  My 65cc-71cc saws get the 20"

Yes that is a good deal on a running cutting 026 especially up your way with saw prices.

Thanks guys.

Cut for fun, how much difference will your muffler mod (from other thread) make on an otherwise stock 026?  How large can you go on the opening safely (need backpressure right?)?  Is the carb tuning afterwords just tweeking the h/l adjusters or rejetting?  Not looking to build a comp saw, but want the best RELIABLE performance I can get for woodcutting.  Some of the guys from our church occassionaly go on trips to cut firewood for bible camps in interior Alaska that heat primarily with wood (150+ cords a year).  We go for a week & its a several hundred mile fly in trip from the nearest "big" town, so reliability is huge.  I hate having to use their very well used saws as a backup.  Cutting spruce & birch, mostly 16" & under.  Same at home but MUCH smaller quantities!

660mag, I love decals!  Already found one  :-)  Cheapest way to go fast is decals!

Do you have a carb with adjustable H side first?    You will look at carb and see 2 side by side  H and L and then 1 I idle screw.

Yes opening up a stock 026 muffler cover helps. Just make sure you have a carb you can re-tune afterwords. 

See which muffler you have on your 026. I think there was 3 covers and 2 backs. Not sure anymore.

Stock 026 muffler covers and backs. Some are choked up with baffle and some open.

The Walbro wt-194 is fully adjustable 026 carb I know of.

Don't have the saw sitting in front of me but I am 99% sure it is the fully adjustable carb.  Looks like I will need to pull the muffler cover when I get a chance to see what I have. 
Thanks for the pics.  I'm a visual learner  :-)

FWIW picture number three is what I dealt with on an 024 before I modified it .Which as the picture indicates is greatly choked down not lending itself to great flow in it's stock form .

Hey Cut4Fun2, I finally had the time to take the muffler cover off.  It matches your pic #2.  Spark arrestor screen is clean.  Any point in modding it???

Thats  about as good as it gets stock.  So it's your call.
 Me I would dremel all the holes elongated to make 1 long hole (thats just me).  Some would just make existing holes larger by drilling.   Take a look at your exhaust exit to see if you can open it up some by using a screwdriver to pry opening or dremel existing opening open more.

By Exhaust exit do you mean the outside (exit) of the exhaust cover or the muffler housing where it meets the jug?

I've still only got a half dozen tanks through mine but I'm really enjoying it!
I'm used to bigger heavier saws (I alway thought the 041 was a little saw), but now that I realize I don't need one for what I'm doing, I'm REALLY enjoying the light & good cutting little 026.  On a week long firewood cutting trip to a bible camp in interior Alaska last year I took my Jonsored 670.  When I leave next week I'll be taking my 026 & my Husky 257 will be there for a backup.  The 670 will be a loaner if anyone needs a saw for the trip!
The Husky 3120 definetly won't be going ;D

Here is my Stihl 026 PRO. The picture is by cut4fun.

It carries a Stihl 16" bar and Stihl 3/8" X .050" RSC chain with a 7 pin rim.

It will really turn up the RPM. A very likable light weight compact limbing chainsaw.

It is wood's ported with a pop up piston supposedly by Dan Henry and a muffler mod. The carburetor is a twin needle Walbro WT-194 with a regular metering valve cover. The extra hole in the air filter is stuffed with a foam ear plug.

All the parts match the type 4 in the IPL except for the carburetor.

I was able to work on the cover a little with some fine sand paper and rubbing compound to remove some of the sun fade.

That same picture is in the other 026 thread.

I suppose I should take some new pictures on a sunny day?

Just pick up all the parts I needed for that 026 I have at the saw shop in Woolley

I got the 194  ;D

The Walbro 194 doesn't have the compensator type metering valve vent like the later 026 carburetors did.

I chose to not run the compensator and I plugged the extra hole in the air filter with a foam ear plug like is described in the other thread in the forum..

But if your old carburetor was the compensator type and you would like to run it, just use the metering valve compensator cover from your old Walbro on your new WT-194.

The compensator merely takes its pressure reference signal from inside the air filter. Supposedly it helps to keep your mixture balanced as your air filter becomes more plugged. But some people do not like it.
