Pull it out and clean it then put a dab of loctite on it and re-set it. That should hold it for you. I even had a dime soldered on to the top of it for easier adjustment. I've never had an issue with mine but then I pull my carb apart quite often and reset everything due to our dirty fuel.by taking out the screw, will that cause any problems with the carb. ajustments, or is it just a screw that holds the butterfly opened


Like Ray said add a "dab" of loctite of just plain 'ol silicone to the threads at the base once it set properly. :2thumbs:Pull it out and clean it then put a dab of loctite on it and re-set it. That should hold it for you.
