What would cause a brand new chain for not cutting
Maybe I'm reading this wrong, but it sounds like you are saying your chainsaw is newer and runs fine, but it just isn't cutting wood well?
If that is the case then it means the chain wasn't sharpened correctly. Lots of guys do it at home and don't file down the raker teeth in front of the cutter heads, so the teeth don't grab into the wood and just nibble at the wood and make fine sawdust. It is always best to get the chain sharpened at a saw shop first so you can get an idea of the correct angles and depth of the rakers etc. After that you can try to match the saw shop for a while with a round file to take off ragged edges unless you have a decent professional saw sharpening unit.
First, like another suggested, make sure the chain is on correctly. Next inspect the leading edge of the teeth... do any look rounded off? They should be nice and sharp, concave in shape and no bluntness at all. If it is a new chain, the rakers shouldn't be an issue. Sometimes just a slight touch into the ground with the tip produces enough 'dullness' to effect the chains ability to cut. Never allow the tip to dip into the dirt...there may be a rock hiding in there. Also don't 'ride' the saw...in other words, don't push down hard as it will cause the teeth to bind and stall the centrifugal clutch.
Is your chain on the right way??
Is the chain on backwords ?
Trying to cut hard wood would do that. If wood has been seasoned (dried out) your going to dull the chains teeth. Chainsaws will only cut fresh wood.

Sound like the carb was never adjusted right. Unfortuatley, the carb adjustment screws require a certain tool that's not available to the public. (EPA thing) You'll have to take it to a shop to get it adjusted. That should solve the problem.
SOURCE: Have a Poulan Gas Powered Chain Saw, I haven't started in 10 yrs.
Not used in 10 years. Was there gas left in the tank? If so the carb is likely gummed up and may need to be taken apart and soaked in "Gunk" solvent and a new kit installed.
SOURCE: i have poulan micro xxv chain not being oil when
wow thats an oldie, That saw uses a diaphragm pump located just above and in front of the clutch drum. Its going tobe hard to find one if its bad, Try cleaning out the oiler hole in the bar first, Then try running the saw without the bar and chain on and see if it pumps.Also check the oil pickup tube in the tank, It has a small screen on the end of it thats prone to sawdust clogging it. If it still does not oil then I suggest you locate the gasket and diaphragm for the pump before you take it apart. Remember to clean everything before reassembling,, Good luck
SOURCE: why my chain saw always cuts at an angle
a lot of people have this problem with a chain saw and cant get a strate cut, most of the time its down to them trying to force the saw through the wood and in doing this the saw cuts around corners as there pull is not square to the cut,, let the saw do the work, not you, if your pulling on the saw to make it cut well then it has a very dull or blunt blade,,,is there any side to side "rock" on the chain in this new bar? how have you sharpend it? dose the chain have the same pitch on both side's? are all the teeth cutting at the same depth? if its cutting around corners it could still be the chain pitch worn out, if so the chain is past its best as well, but most of the time its all down to how hard and how squarely your pulling on the blade when cutting,,,the first thing in logging to lurn is to cut squarely no easy task that! just dont force the saw to cut!! it will cut just as fast or faster without forseing it,, if all this still dont get you cutting right change the chain for a new one,,,the only hard work with a chain saw is holding it up to the tree and humping it around not cutting with it, thats the blade's job to do so the faster you try to make it cut the more out of true the cut go's as all your doing is bending the bar out of alinement,,all in all, its two hands for the job and a very gentle pressure on the saw, start the cut with the blade spinning and dont stop the blade in the wood, cut right through
SOURCE: Chain saw cuts at an angle
I have seen this problem of a chain saw cutting at an angle brought up again and again on forums, and result in a variety of answers about sharpening the chain, or replacing the bar and/or chain. In a number of these requests for solutions, none of the advice has solved the problem. I have used chain saws for about 45 years now, and there is a condition that some chains develop with the pitch of the teeth or the guides...or both...that will cause them to cut to the left or right at an angle (usually left). While I have not figured out what causes this, I have solved the problem of correcting it. First, turn the nose of your bar and chain toward you on a bench, look down it like sighting a gun and take a look at each tooth and guide. If the saw is cutting left, the teeth or the guides (or both) on the left (while you are looking down the bar from its tip) will be pitched differently than the teeth and/or guides on the right. The pitch of those teeth or guides (those little ears that stick up about on-fourth inch in front of each tooth) will be: 1) too much in line with each other, or 2) the teeth or guides will be less pitched than the teeth or guides on the right side of the chain. Solution: take a large pair of lineman's pliers or similar pliers and pitch those teeth and guides to match those on the right side of the chain. Also, make sure the curved part of your chain teeth peek out around the outside edge of those guides. If the guides are directly in line with your teeth, they will hinder cutting by the teeth. You can do this with the chain on the saw if you don't have too much slack between the bar and the chain. Last, make sure that the chain guides are not as tall or taller than your teeth. If they are, you will need to file them down a little (with a flat file) until the teeth are slightly longer than the guides. Afterward, make sure the teeth on both sides are equally sharp, and go cut a straight cut! TennesseeBob
