Go to ZTherapy and buy this video: “JUST SU’S” British HS6 and Hitachi “SU” https://ztherapy.com/just-sus/ Watch the video until you name every part and understand how the SU works. You are experiencing a lean condition. Note that the throttle shaft on the SU tends to wear out allowing air to leak into the carb causing a lean condition. This air leak makes proper mixture adjustment impossible. Contact Ztherapy for the fix.
