With the amount of money you spent there,they should stand behind the product. Glad they did.

You can't replace 090 engine displacement with a smaller displacement saw.
I milled with my 1994 090AV for over 20 years and even tried a well broke in 880 on the mill. The 137cc 090 outclasses them all if milling big timber.
The 090 has more displacement and maybe more torque. But the 088 has more hp output because of higher rpms.
I have milled hundreds of hours with a 088 and that saw is a beast, have cut some 20" wide ironwood, that just like glas, 8' long one tank per cut. when you finish the cut the oil left almost boils the saw gets so hot, it's amazing these saws can take such abuse. 95 degrees temp and 90-100% humidity. And with .404 chain, we don't have such things as low profile chains, skip or semi skip here. not available  
I think the 088,880 and 090 are comparable for milling.

Teakwood, one thing I have noticed with my 880 is that it runs cool. Quite often I need more than a tank of gas to finish a single cut. I don't even shut the saw off to fuel up. Just leave it in the cut and pour some gas in and keep on going. I think it's running really rich which is keeping it cool but also using a lot more fuel than it should. I can run two tanks straight of fuel through it on a 90 degree day and the plastics are barely warm to the touch.

Teakwood, h.p. specs of the 880 and 090 mean nothing.
You need to try a 090 milling and especially a 090 with its govenor disabled like I did with mine that raises its h.p. off the chart.

Not only does the 090 have 15cc more displacement it also has a oversized outboard clutch with brake lining material on the shoes and a finned cast aluminum muffler... that keeps the engine much cooler then a 880 under the heaviest cutting milling.

But as I said disable the 090 govenor and keep the H speed screw set at light 4 stroking and run it 32 to 40:1 and that saw will surprise you.
I disabled mine right from day one when brand new, ran it that way for 20 years.

A photo from the spring of 2005 with a contract I had with the local pulp and paper mill. I bought this 090AV new in 1994. I bought my first new 090 in the late '70s.

As the photo shows for several months 12 hours a day my worker and I cut these cull (not suitable for market) 54 inch diameter 14 foot long kraft paper rolls in half to fit in the repulper machine.
With a mile of cement bag strength paper in these rolls, this was the hardest thing I ever cut.  

The 090AV with govenor disabled took 5 minutes at WOT to make the one cut. Only chain that would stand up was Stihl .063 harvester chain on the 5 foot bar with helper handle.
Saw was using up 5 to 6 gallons of gas and a gallon and a half of bar oil a day.

By the start of summer temperatures were in the upper 90's and we were wearing shorts under safety chaps.
But the heat didn't bother the 090, she just kept on motoring. :)
On a good day over 40 rolls cut.

Yowza.  I can see where one of those stack cutters with a harvester bar would have been quite useful there, or even a modified slasher saw.

Yes the mill did end up buying a expensive hydraulic gillateen machine after my contract ran out.
At the time they had a few years of these cull rolls stored in their warehouse and gave up recycling them back into the repulper with a carpet knife. So they hired me for a $100 an hour. It was good when it lasted.
The 090 briefly stopped for a few hours when it's exhaust ignited the paper roll and cuttings underneath it. The saw was stuck mid cut with wedges driven in tight above it.
By the time I got the fire hose out and put out the fire the paint was burned off the 090 covers, fuel line burned up , spark plug cable insulation burnt off.
I wrapped electrical tape around the bare exposed spark plug wire, the foremen gave me a piece of rubber hose to replace the fuel line and I was back cutting.

Holmen, that there looks like no fun at all!
I was 47 then and yeah 12 hour days doing that is tough for any age :D
Actually the first week on the job I did it alone. Quickly came to realize being 21 years old was a long time ago.
So I got a helper to man the other end of the bar, that sure helped.

Today, almost 61 I'm still climbing, dragging brush, feeding the chipper, cutting and loading rounds . Grinding stumps and throwing buckets of stump chips on the trailer. Been working alone doing this 5 days a week for the last 10 years.
Wouldn't have it any other way. ;D

Here's a pic of some of the burnt 090 parts I kept. About 10 years ago I was able to buy brand new OEM covers from Stihl Canada.
If it was a 880 it would have been a melted blob.

Last pic is the same saw near completion of restoration. I sold it to a young guy in southern Manitoba.

So what your saying is that the aches that you feel in your 61 year old body don't compare to the pain in the butt an employee can be?😁 And again, that saw might look better when you got done with it then when you started. Nice work👍

Thanks barbender, it was a long restoration and proud to say no Chinese parts went into it.

I got no aches or pains not yet anyways. Bigger pain is trying to keep a right hand man to do bullwork. When I did have employees I once had 6 at one time, now that I can tell lots of stories about :o.

Strange as it might seem I saw for the first time an 880 Stihl in  use just last week  .It was by a tree trimmer taking down about a 30 inch dead white oak in my neighbors yard .With no bad mouthing the saw it certainly did not have the  guts as the 084 I had residing in my shed .Restrictive exhaust I suppose .
Being somewhat of a show off I showed the trimmer what a good tuned saw cuts like .I wanted to check for metal in the log by  looking for blue in the wood and cut the butt end off the log with an 038 Magnum that peaks out at 14,600 RPM .He was  speechless ,I was amused . 8)---ain't I a stinker --- :)

Update. Got lucky, the electrode was in the exhaust. No cylinder or piston damage. They agreed that it was running too rich and couldnít get the carb adjusted properly. They have a new carb coming tomorrow. All covered under warranty.

Honestly I would want to see that , even at idle just figure out the number of rpms that piston is going up and down past the ext. port . Just my small thinking but its a very small window for any piece of metal to get out into the ext port without the piston catching it and driving it into the roof of the port . I seen this lots when I was working at a stihl dealer and pretty much always nailed the piston

Ehp, my neighbor is a retired stihl tech and said heís seen it go both ways. They said they took plenty of pictures to show me. This place has an outstanding reputation around here and I doubt they would try to pull anything dishonest. They have said and another local dealer as well as me neighbor that Stihl is easy to work with on warranty claims. I donít see any reason for them to lie about it.

Well I picked up my saw today. No damage to the engine and new carb installed. The thing screams now, crisp and snappy throttle response. It's a whole ne animal now. Pretty much buried the 47in bar in some dried redoak log I had here and it just ripped through it. Very happy with the dealer and the performance of the saw.

I'm glad to hear they took care of you!👍 I thought your plug looked really black, did they think the rich mixture had anything to do with the electrode failure?

They didnt really say anything about the cause of the plug breaking except that it happens occasionally.  Ran a few tanks of fuel through it today milling with a 60in bar and it was ripping right along. Wish I would have brought it in months ago. Would have saved me hours and hours of cutting time.

I'd run Bosch plugs in it just in case what happened to your NGK.

I always had good luck with Bosch the 40+ years I ran them.
