throttle problem

The other day I went on a 7 mile trip and ran my bike at mid throttle most of the way there.

everything on my motorized bike is working EXCEPT.. when the motor kicks in, twisting the throttle does nothing. the engine will run until the bike slows down enough that the engine dies. when twisting the throttle it stays where ever i set it and it does not spring back like i think it is...

I just finished my engine kit about a month ago, had it running fine, but now i'm having some problems. I have the stock throttle on my bike right now, and it seems that before last week when i twisted the throttle all the way, the engine would run at full power. Now though, its like the engine...
