This ^Generally happens when one side is sharpened more than the other. If your filing set up doesn't make the two sides consistent, then you'll pull to one side.
I agree with you on the number of strokes when had filing. I do 6 to 10.. I get it on the grinder if I have to file the chain twice. I keep about 5 loops of 18 and 4 loops of 20 with me when I go cuttingThis ^
When I first started chainsawing, I ran into the "curved cut" problem. I had just hand filed the chain when this problem occurred, and the bar was fairly new.
Instead of 3-4 strokes per tooth, I tried 6 strokes per tooth, and then the saw cut straight. The issue (apart from my inexperience) was that the chain had become very dull, and I hadn't removed enough material from the teeth to the point that any variance in my sharpening technique from one side to the other wouldn't matter.
Also, if hand filing, I highly recommend using a file gauge to help with consistency until you become that "pro."
Yeah, for me 6 strokes is about is the minimum if it's not just a touch up. That's with hard Stihl files (or similar) on Stihl chain.I agree with you on the number of strokes when had filing.

most people have a hard time sharpening a chain,then throw in the awkward side because most people are not ambidextrous the awkward side doesn't get the same angles or attention.I say sharpen your chain and check the bar for Where run your hand along the bar if you feel a lip where the chain groove is your bar is getting worn. and its time for a new bar....
PRO TIP when sharpening your chain on the saw.. take the break off and rotate the chain forward to sharpen all the teeth... no need to flip anything... thats like super awkward..
Well, technically, he said,OP said he just put a new chain on and it still doesn't cut straight. Therefore,....
Which at least makes it sound like that new chain cut a 'big' maple tree plus some locust, 'then' won't cut straight.I put a new chain on it, cut up a big maple that fell then a little more locust and now it wont cut streight [sic]
