Stihl 090
« on: February 24, 2017, 07:55:50 pm »
I do not think I posted any info on this saw that was brought to me for some work.
When first brought to me I just tuned it some and cleaned it up and verified that the oiler was working ok.
This is what it looked like when I first got it.   It seemed to run ok and so I gave it back to the owner.

Well about a month ago I was helping to take down a big Elm tree and the owner of the 090 was going to stump the Elm and it started running bad so I brought the saw home again to look at.    I rebuilt the carb on it this time a Tillotson and man does this saw run good now.   I think it actually picked up some RPM from before and when put in the wood it went into 2 stroking it really sounded strong holding the RPM's well.   I also put a new bar and chain on.   36" bar with .404 chain.   

I did some noodling with it and those big chips crack me up.   All my stuff is 3/8ths.

There are some 100 year old cottonwoods around here.

I keep looking for a complete one that won't break the bank, they are fetching a good dollar here for milling. A mill I used to do service for supplied the saws to the fallers in big WRC, to simplify inventory they only had 090's. The barker saws ran 24" bars, I had to adjust the governors to keep them from over speeding. The operators couldn't load them with the short bar.

What RPM did you adjust the governor for.   I do not really like the governor on this saw.

I honestly can't remember, that was in the late 70's.

I never bothered putting a tach on mine.
I disabled the govenor completely and just set the H screw like any other old school saw.
Never had a problem.

But if it's a customer's saw I wouldn't advise disabling the govenor. :D
My 090 owner manual says don't exceed 8000rpm.
