Default Terrible noise under power and pedal

Well I took my 80cc china beach cruiser out on its maiden voyage just now. I am thrilled.

However, there is a great deal of noise coming from the engine whenever the engine is off and I am pedaling. A fair amount of resistance too I might add.

It is a high pitched noise with some whirring. Please be aware that the clutch is not the culprit. The noise persists when the clutch is engaged, the engine on and cruising.

When I first got the engine, pressing the clutch would not do a thing. I opened the clutch cover and was able to lock the large gear in place while I force the small deal in the middle to move, it broke loose and the small drive sprocket would then move when the clutch was disengaged.

I feel like the problem is a lack of lubrication between those two parts, which is probably why they were stuck to begin with.

Sorry for the long post.

Anybody had this problem? Am I on the right track?
