Default 1989 Moto4 No power

I have a 1989 Moto4 ATV...Barn Find....Just got it for something to tinker with....Started right up, Idles fine but has no engine power what so ever....Installed brand new OEM air filter, Brand new Intake joint tube. All new exhaust gasket because it leaked pretty good..exhaust silencer has a small whole in it and i welded that shut.. NO more leaks.. Bike just sounds like its starving for air to me...THe headpipe is also glowing cherry red up towards the motor also...I know that can be somewhat normal sometimes but its pretty red.. Is it lean? Dirty Carb maybe? Running out of ideas.. Any help would be great...

It sure sounds lean to me. Something that old probably needs the carb rebuilt.
