I would first verify what bllsht pointed at, the fast idle cam being
stuck as that is very common. The fix is a clean with carb cleaner spray.

Next I would have the engine off and cold and give it two shots on the
throttle like you should for a normal start, then open the air filter
without starting it to verify the choke is closed.

I was thinking electrical due to me misreading your clutch settings and
agree the basics should be looked at before messing around.

i checked the cam but it is moving fine. when i hit the throttle the
cam moves as the screw lets it and the choke closed. when i started
the car the choke opened a little bit but still idled at 2000 and spit
gas out very fast.
