I had the carbs cleaned and kitted. I'm at 3 full turns on the mixture jets just to get it to crank and it still dies when idling after a bit. adjusting the Idle screw just makes it run too fast. It's almost like it's flooding after idling for a bit but after it dies I have to choke it to get it back started. Bubble is working. screen in tank is clean, Filter on motor is new.
