2002 Honda XR200R not getting gas

[SquirrelMasterGeneral]

I just put a brand new top end into my 02 xr200, which was a pain because I had to take the engine out, and now I have the engine back in the chassis but the bike wont start. Im kicking it and kicking it and I get nothing. I checked the spark plug and there isn't a drop of gas. I tried using starting fluid and I get nothing again. Im at a loss here. Could it be a stuck vavle?

try to keep things like how it was running before you took it apart a secret.  also make sure how long it has been apart is also kept secret.   cleaning the carburetor is a good idea,  but first describe how you timed the cam,  and if you have valve clearance when the piston is at tdc on the compression stroke.
