GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
I have a 97 johnson 40 hp that starts, idles and runs perfect until i get to about 3/4 of full throttle. After that the rpms surge dramatically. It wont stall but goes from 25mpy to 10 and back again repeatedly. I checked the carbs and filter. No success there. Any suggestions?
