Clutch not working ?

my bike was working fine last night

I went out to ride my bike today and i was trying to start my bike the clutch was working fine, then right when i am trying to start it, the clutch just stops working and the bike just starts driving normal and i can't feel any the clutch at all.

I don't know whats wrong now the motor will not even work because it just drives with no tension at all.

Whats wrong with it ?

give it a try.

(that was in my fortune cookie today, at the "Happytime Buffet")

Its not about the clutch cord, I took that off the clutch and manually pushed it back and forth and the chain does not have any tension at all.

when I used the bike before the clutch had to be engaged before the bike would move, now it just moves when its pushed engaged or not.

I don't know what i have broke ?

is your chain off of the engine sprocket?

No its on but it just goes like a normal bike chain now with no tension at all, there was allways tension before i engaged the clutch and i could not even move the bike untill i enaged the clutch.

The engine sprocket turns fine with chain on, but with no tension.

check to see if the drive sprocket (at engine) is spinning free
if it is, you might have sheared the woodruff key that locks the sprocket to the output shaft
that happened to me while I was riding and caused the nut holding sprocket on to strip all the threads

I made a video for you guys to watch showing the problem, so you can understand it better.

I can't get theses screws off the engine , I have tryed with 3 screw drivers and even hit it lightly with a hammer.

I need to get in there to see whats going on , why are they so tight ?

thanks for the video.... I tend to agree with azk on this one...there is a broken keystock on your front engine sprocket. (allows your engine to spin, but not your sprocket. I know there are some sprocket pics on here. try a search for "removing front sprocket" select search all terms
