Re: New engine does GREAT, but
Noise changes with speed.
Clutch in, Clutch out, in gear an in Neutral, engine on, engine off makes not difference. Sort of seems that the motor and transmission are out of the picture.
Got to look at what is still turning with the tranny in neutral and the engine off.
Drive shaft, universals, tail shaft bearing, rear end, rear wheels.
Can you "feel" it as well as hear it?
Can you time it to speed, for instance does it time to once each wheel revolution?
