I inherited a Karcher pressure washer with Honda GC160. Carb and linkage along with governor arm were in a box. cleaned carb and reassembled. started with pump off. motor runs but at high rpm. Thinking that maybe governor arm needs to be adjusted. How do I do this? Also with pump connected, engine starts but floods after 2 to 3 seconds and will not restart until it sits and dries out for awhile. Also, where can I get a repair manual for the Honda motor? Thanks ahead for any help.
