I am having a problem with my 2008 bigbear 400, can anyone help. When i start it, it will start from normal idle and start increasing rapidly to near full throttle. I have checked my throttle cable, choke cable, cleaned the carb thoroughly as well as all the jets. I know something has to be stuck, but what could this be. Would this be a problem with the throttle valve and or the diaphragm and spring assembely.
