I have a 1998 Evinrude 150 Intruder V6 that cranks and idles great but when I open the throttle the engine dies. I can tilt it all the way up, unscrew the fuel line from the motor and drain the fuel from the motor and put the fuel line back and then it will run fine until I try to run it againg after being stopped awhile. I think it's flooding but I'm not sure how it does just sitting off while I fish. I also just had the oil mixer and oil resevoir disconnected and removed. Any help would be appreciated.
