[AT] Chain saw cutting issues

[charlie hill]

Let me throw in a slightly different perspective.  I had that same problem 
years
ago.  I replaced the bar with no help.  Then I decided I had screwed the 
chain
up hand sharpening it and replaced it.  Turned out, when I finally figured 
it out,
that it was me.  I was putting pressure on the handle with my left hand 
while
I was squeezing the throttle with my right hand and I was causing the saw to
try to turn as it went through the log.  In my case the saw was curving to 
the right
as it went down.  I think your problem is the opposite direction but the 
cause
could be the same.  I figured it out when another fellow was using my saw 
and
didn't have the problem.

I had this problem once.  I pinched the chain and Bent the guides. The part 
of the tooth that rides in the slot.  This causes the chain to lean on the 
guide bar which cause the blade to cut a circle.

If you run it this way the edge of the guide bar will wear which will cause 
even net changes to cut crooked.  You can file the bar if it is not worn too 
bad.  You can also straighten the chain.


Take a close look at the chain and the bar.  See if the chain is straight on 
the bar.

I have a [U]Poulan  18 inch classic, chain saw.   [/U]    and had it for 
years.
Today though, I have issues with the chain blade.

the chain is but 2 months old.  it now will only cut the soft outer wood of 
a log and stops when it reaches the hard wood of the center of a log. It is 
nut cutting straight through a log.  Instead, it is cutting in such a way, 
that by the time the
blade reaches the hard wood...  my left hand is in the air and my right ( 
which is operating the throttle)  is down, and the blade has cut a curve? a 
curve that  heads in the direction of my left leg.
SO I sharpened the blade teeth and filed down the  blade depth gauge just a 
bit...( using a Oregon,sharpening device to do so).

[U]I am [/U]getting short chips  off the blade but the saw shows no 
improvement in cutting abilities and continues to  cut a curve . ???

I have resharpened  and resharpened and even sharpened only the left 
cutters,  No improvement.
then only the right cutters, and no improvement?
maybe I need to sharpen yet some more the teeth on one side more than the 
other?,.... but which...the left cutters or the right?

And it seems that once the blade reaches the hard center wood of a log,  the 
only way I can get and  more shavings is to rock the saw  (
tilt it  left and right in a rhythm,)  but it cuts a deeper groove towards 
my left leg.

Tell me what is causing this curved cut issue ? and how do I correct it?
and why the cutting stops when I reach the hard wood in the center of a log?
