Hi, my name is Matt I live in the Florida Key just got a boat the other day my first boat and it is a 1983 aquasport 17" with a Johnson 140 motor the guy gave it to us. The boat starts up fine and runs but does not want to go over 5000 rpms. I just decided to take it out of the water and clean...
If I spray carb cleaner in the carbs when the engine is running to try to flush anything out could I do harm? The motor runs fine till it hits about 5000 rpms then falls flat on its face? 140 Johnson 2 stroke motor.
