I just replaced the blade on my chainsaw and it doesn’t cut. I checked the direction and it not backward, I used the directions for tension. I just can’t think of anything else. It appears to have a depth limiter built into the blade and it seems like it is higher than the blade itself. This blade is new and just like the old one I pulled off. I can’t think of anything else to look at.
Without pictures, this is hard to diagnose. What do you mean by “doesn’t cut”? Does it cut too slowly to suit you or does it not cut at all?
Are you sure it’s not backwards? I ask because I had a neighbor make the mistake once upon a time. On the top of the bar, the cutting edge of the chain links should be facing away from the saw motor.
The “depth limiter” is the drag tooth at the front of the tooth link. It’s job it too prevent the cutting edge of the tooth from digging in too deep. It’s hard to imagine that it’s too high on a new chain. Lay a straight edge on the top of the link. What is the angle of the straight edge? It’s possible for the tooth to have been filed down a lot and the cutting edge to be lower than the drag tooth, but I’ve only seen it on very worn chains. The solution is to file down the drag tooth if you don’t want to buy a new chain.
I confused the drag tooth with the cutting tooth and had it backwards, I feel like a dummy. And then to make it worse I thought the tooth had been filed down too much so I ruduced the hieght of the real tooth. Now I have a brand new blade . Feel like a dummy!
I had a reply all typed out but on preview I see that the problem was what I thought it was. Don’t feel bad. I’ve been there, done that, too many times myself.
For the benefit of anyone else coming into the thread I was also going to ask if the chain was getting lubricated properly as a clogged oiler can also cause poor cutting.
I did read up on the oil while I was troubleshooting and found I had the wrong oil also. I know a bit more about chainsaws today than I did yesterday.
Don’t feel too bad. I know several people that have made that mistake. I made it once with a bandsaw blade on my sawmill.
I’ve also had a chain saw fire and run backwards. I didn’t realize it until I laid the saw into a log and felt it push back toward me. It was a strange feeling, indeed.
I couldn’t find this yesterday. Here’s a picture of a perfectly sharpened tooth. Notice the difference in height of drag tooth relative to the cutting edge. That’s what controls the depth of cut for each tooth.
I wonder if those lumber jacks with the turbo charged saws lower the depth gage. I should have put on my glasses yesterday, I would have seen it better.
You already have your answer, but don’t feel bad about it. We’ve all done it.
I haven’t. 
And its not a blade, its a chain. 
We’ve all done it, but not all of us admit to it.
Try spending a couple of hours manhandling a C4 transmission back on yourself, tightening all the bolts, and then look over and see the spacer laying against the wall of the garage.
