After my little mishap with the range selector I decided to give my YM14 a birthday and see if I could work out why it is running so rough. I did degrease and pressure clean it whilst running and noticed it coughed when I sprayed water around the inlet neck and injectors. Broke out the brake clean and started spraying. Found an injector seat leak on No1 and a bad one on No2, maybe they were never put back when it was last pulled to bits? I will pull them out and see what condition they are in if there are any installed....
