When Cutting Large Dia, Wood Saw Curves To The Right. I Have Sharpen The Saw And The Teeth Look Even Any Suggestion
 
If the teeth are even in all angles and dimensions, check your depth gauges for uniformity and bar rails for squareness.

Shouldn`t you have posted this in the chainsaw forum?

And take a look at the bar -- has it been 'bent' or 'twisted'? Tough as they are, if you struggle with one in a bind, instead using a wedge or getting some help removing it, you can easily bend or twist a longer bar. A friend of mine put one in a vice and man handled it back into a fairly good alignment; but, this was for a 'fireline' saw, not a day in and day out work saw.
 
I just had this happen to my 51 husky, it turnded out the sprocket was worn out started cutting uneven. I didnt realize it until I had the whole bar in wood, I could see it was cutting circles where the tip was.
 
If your chains is fine, and the bar is straight, then the bar probably needs grinding. It needs two square and not rounded shoulders exactly the same height. Yes, you can got it with a file, but it's a real pain - just take it to a saw shop - it only takes about 5 minutes.

If you have a wood working disk sander, the type that has vertical disk about 10-12 inches, and a table at 90 degrees, you can do a pretty good job. Lay your bar down flat and grind in nice long even strokes. Clean up any edge burrs with flat file.
 
Duffer.... wait... i know the problem... took me a newbar a new chain and a new sprocket on my Husky 136... turns out that it was the clutch assembly... the shoes were not engaging straight on the inside of the sprocket... the inner sides were(engine side) were grabbing the sprocket... all that trouble and all you need to do is take off the clutch remove the shoes... take a little sand paper and sand on where the shoes move on the hub.. should fix you right up... ps it wouldnt hurt to put a new spring or spring in there while you got it apart.
 
Squaring up bar edges:

Hello to all. What I do is to center a 10" grinding disk up against the blade (mounter backwards) of my table saw, tighten everything down and grind the edges of my bar that way. Then use a fine flat file to smooth and remove burrs and finish up with some fine emery paper. Take care. Lewis.
