Yet, on my very first cut itself the wood started smoking, and the saw would not go in as smoothly as it should be.. But the cut was not that bad at all, and that made me doubly confused. Later on, after reading through multiple posts, including this forum, i realized that i made the mistake of putting it on in the reverse direction - actually, the blade was meant for a standard clockwise rotation cut, but my machine ( a cheap one ) was expecting an anti-clockwise blade.

I just reversed the blade, and voila! burning stopped, cuts are much more cleaner

All the videos said have the writing side of the blade facing out, but in the end, the blade was on backwards, and hence the smoke and burn. It's not a problem with saw, or anything else, the bottom line is the blade goes the opposite way you would think and assume. I turned it around and perfect cuts with no smoke.

Beware of poorly written owner's manuals. You might think you followed directions to the letter. And then discover like I did that the pictures don't always match reality. In my case the markings (holes) of the blade intended to show blade rotation were backward from what the manual shows. So yes, the blade was backward and caused smoking and lousy cuts. It's true that before trying a cut the teeth are the best indicator of proper blade orientation if you know what to look for. In my case the teeth are shaped so that it's hard for a newbie to tell at a glance whether they're "pointing up" at the front of the saw. I thought the teeth were pointing up, and those dang holes in the saw were the same orientation as shown in the manual. But it was wrong. Once the blade was mounted correctly it cut easily and straight without smoking. The business edge of the teeth should rotate "toward and into" the saw (or "up") at the front where it cuts. Looks to me like there are two surefire ways to know if you've got the blade right or wrong, regardless of any blade markings. The teeth can tell you. And the smoke and rough cuts do too.

I had this issue with a pretty decent Makita circular saw and I found that the problem was indeed wood resin residue. But it was mainly on the inside - invisible side - of the blade, so not obvious until the blade was removed. It wasn't easy to remove the gunk but a wire brush on a drill plus some thinner did the trick. I thought of just running the saw and sticking some steel wool in there but decided against it. (Just kidding - DO NOT DO THAT!) The other thing I think I was doing wrong was not running the saw through the material fast enough; it was my first circular and I was a little timid. And obviously, the type of wood makes quite a difference. Brazilian teak is like iron and is quite resiny.

A circular saw blade section that is "inside-invisible"? Say how...
