i finally decided to go out and cut a big tree and so i took my 090 out for a test run and we found this tree to cut it with. the trees measured from
50''-69'' in diameter because they are not circular which made them fun to load. i was using from what i see is a plain stihl 090 with a woodland pro 50'' bar and chain and all i know is it worked GREAT.

lol yeah well a 21'' is to small for me or even the saw. i use this saw for big wood as it should be used in my opinion.
 
injun joe is your governor disabled? If it isn't try it with it off, power and speed goes up big time. Just keep an eye on your high speed setting.
I have run mine for years nongovernored and never had a problem. Just wrap the spring tail around 1 turn and rehook it to the first notch.

well i dont know what the governor is. is it on both the gear drive and just the non gear drive. could you show a picture of this governor.
 
Take off the top cover ,not just airfilter cover, and at the rear of the starter cover you will see a small metal flap with a fairly fine spring. The flap is on a shaft which is connected to the choke so over rev and the choke comes in and shuts down the saw.

Im glad Holmen brought this up since I was wondering where it should be set, the spring slots into a notched plate, so Iam sure an member will let us know the correct setting ! Ive just bought a 070 tonight so am keen to know the correct setting for the gov' for both my contra and 070.

Is your 090 running on .404 or 1/2" chain ?

The wind from the flywheel fan blows against the governer flap which is connected to the choke butterfly on the carb. More rpm makes more wind which closes off the choke. Yes there is about 4 notches [ haven't looked at it for years now.] The factory setting was about in the middle locked down with some resin. I found even at the highest notch setting the choke governer still came on easily, so I just wrapped the spring tail all the way around the shaft and hooked it back into the first notch. Now the choke governer never comes on.
I run Stihl .404 harvester chain to cut those paper rolls as my earlier picture shows. Regular .404 couldn't stand up at WOT for 5 minutes in those tough paper rolls.

Why does harvester chain work better?

Holds a better edge and doesn't stretch as much. These cull 54"dia. paper rolls I cut in half for our local mill so they could fit them into the repulper, are the toughest thing I have ever cut. 5 minutes WOT with a sharp chain.

yeah im running a .404 50'' woodland pro bar and chain and thanks ill have to take a look at my 090 i really dont wanna mess with it i bought it form some guy and i dont know if he knew the idle screw was busted off or possibly my dealer broke it off while rebuilding the carb i dont know and im not even going to make any assumptions.the saw currently runs good as i have said and its fine for the big rounds we have laying around here. well someone asked where or how do we find wood this big simple my 69 year old grandmother scouts out the wood for us and sometimes we just happen to come to a clearing in the willows and there there are. not to uncommon to find cotton woods upwards of 5' around here. just they taper off really quickly.
 
anyone else used .404 harvester chain on a standard chainsaw?

I have 2 bars(39" and 44" I grabbed off Ebay (harvesters) that I had re-drilled for the large mount Stihls(lost 2.5" on both). I have a 75' roll of harvester chain(.404 .080) I also grabbed off Ebay for $42

So all in all I 2 large bars and 22 chains for under $90 for the 090G's!!!!!!!!
 
injun joe! That is a nice looking saw with that big ol'cannon on it!!!!

Something different happens when you really run them with a HUGE bar!:yourock:
