ok guys so i bought the motor used and first time i used it, it would run for about 10 seconds then stall so i cleaned the carb and got new fuel lines and it still did the same thing but i figured out that if you keep reaching back while its running and switching the gas on and off that it will keep running but if you keep the gas switch on it will stall if you have the gas switch half way it will still stall so i put the motor in a bucket and tried to tune it and got it to were i could get it to run fine on full throttle half throttle and low throttle without having to turn the fuel switch on or off so i tried to put it back on the boat and in the water and it did the same thing and kept on stalling on me does anyone know what i can do to fix it or know whats wrong with it? thanks.
