I have a Tohatsu 9.8 that will not return to idle after it's run for a while. The cable are not binding and and the butterfly valve returns to the idle screw when the engine is off, but it won't return when the engine is running.
We recently had the carb replaced to correct other problems. Any ideas would be helpful.
Thanks
