hey im new to the forum and am having a problem already with my 84 honda 250r. I bought this about as month ago with the engine bored .50 over. Last week i went out to start it and the engine started revving super high to the point i couldnt shut it off. I replaced all my vacuum lines and the air filter is fairly new. The slide is not stuck in the carb and seems to be working properly. Any suggestions out there? thanks in advanced
