Have a well maintained late model Honda 7.5 HP outboard. (blue/white)
Will idle and spool up perfectly for the first five minutes of operation. After 5 minutes of warm up time, motor will idle and troll perfectly all day but will not throttle up fully (stuttering hesitation). Carb has been removed cleaned, plugs are fine, fuel is new, breather on tank & check valve cleaned and work properly. Problem seems to be heat related. Motor acts like the timing advance (if this motor has this) is malfuctioning. What's the fix for this situation?
