Hi i own a Yamaha Terrapro it is in great shape but the motor does not want to idle i know that there is an idle adjustment on the engine but it will not turn anymore i think there is something wrong with it it runs but you have to keep constant presure on the throttle.

 

My first guess would be that you have a clogged pilot jet, so you're not getting any fuel through the idle circuit. Try tearing down the carb and giving it a good cleaning, see what that does for you.
