Are you attempting very deep cuts, rather than successive shallow cuts?

Is your saw underpowered for the density of the material you are cutting?

Are you pushing the material through the blade too fast?

It is not the number of teeth that is the problem. Either the wood is warped. your fence is not square, or the wood warps while it is being cut (use a riving knife).

There are other reasons such as dull blades, or dirty blades (sap covered). Regardless the reason, certain woods burn more since they are harder or have a grabby like grain structure.

Also you may notice that the blade will burn whenever you stop moving the wood (even very briefly while repositioning your hands, so be very consistent on your feed rates).

The MOST IMPORTANT thing is to only feed very straight wood through your saw, for safety, to reduce burning and accurate square measurments.

I found that some woods are much more prone to burning than others. The hard woods in particular will get scorched a lot easier. The worst one I have cut has been Elm. The same blade would sail through pine and even oak but would scorch and even smoke cutting Elm. So the wood you are cutting will have a lot to do with getting burn marks. If it is burning then try slowing the feed rate down. I actually thought about trying silicone spray on the blade to reduce the friction but never tried it. So you could try that and see what happens.
