just rebuilt runs bad

I'm guessing you might be a little sketchy on the anacronyms. This might help even tho it is a little general:
In regard to the cam card degrees...
The engine has 360° of intake valve cycle that spans two strokes. The intake opens After Top Dead Center on the exhaust stroke and closes After Bottom Dead Center on the intake stroke. Bottom Dead Center (either BBDC - Before Bottom Dead Center or After Bottom Bead Center) means the piston is down at the bottom of it's travel, and is the 180° mark on your tape lining up with the timing cover "0" mark. The intake valve closes After Bottom Dead Center at the beginning of the compression stroke. As before, Bottom Dead Center is going to be the 180° lining up with the zero mark.
The exhaust valve cycle also has 360° that spans two strokes. It opens After Bottom Dead Center of the power stroke and closes After Top Dead Center on the exhaust stroke.
You have to keep the four cycles in mind when you read the cam card and track the number of degrees as you turn the crank and count.
