Noise and rotating pedals questions

I've read about adjusting the clutch if it doesn't disengage properly. I understand that it'll make lots of noise if that's the case. Will a too-tight clutch also make noise when the engine is off, the bike is rolled forward, and the clutch is disengaged? Also, should the pedals still rotate when you roll the bike forward under the same conditions? The pedals will stay in place if you hold them in place (with a bit of resistance) but will rotate if left alone. BTW, the bike is a Pacific cruiser with a coaster brake.
Thanks from Austin

Thanks to you both. I think my pedals want to rotate b/c the back wheel is not spinning completely freely, i'll have to figure out what I did to cause that.
