With good clear white pine you shouldn't get that much burning. I have never had burning during miter cuts on pine. Are you using more than 3/4 stock, is it a carbide blade with the proper tooth count, at least 36 -40 teeth? Saw underpowered? Just don't sound right to me with good clear white pine. If it is southern pine then that stuff is good and hard and full of pitch and resin.
