Bandsaw blade burning wood

I have a 14″ Rockwell that the blades are burning wood. I just put on a new 3/8″ 3TPI Timber Wolf. I was cutting 3/4 inch pecan as a test cut and fed the wood at different rates. The slower feed burnt more but I was still getting burning at faster feeds. This has been happening ever since I put a new motor on the saw. I previously has a 1/2 hp 1750 rpm and replaced it with a 1 hp 1750 rpm motor.

Did you have to replace the motor pulley? If the new pulley is a different diameter, the blade speed will change.

Did your old blade cause burning also? I increased the power of my 14" Delta a few years ago and did not have this issue. It sounds like maybe the wood is pinching closed on the blade as you are cutting. Have you tried some different wood? I suppose it could be a defective blade. Have you got another one you can try?
Just a thought: could your guide blocks be too tight causing the blade to heat up? Bandsaw blades are so long and thin, I can't think of anything else that would cause them to get that hot.

Is the blade on right? I know a guy who had the teeth on the blade reversed.

Is the new motor turning in the same direction as the old one?

Sounds like a feed rate or dull blade issue...assuming the saw is working as designed and the blade is not inside-out.
