I have a 06 50hp Yamaha that is hard to start when cold. I squeez the bulb a few times, hold the choke in for a couple of seconds and it's still takes a while to start. I know I have a Prime switch and it is in the correct position, today when I first started it I flipped it clockwise 1 turn to the "ON" position. The baby fired right up on the 1st turn, ran it out on the lake and it smoked really bad and ended up dying on me. Put it back into the "Normal" and got it going. Any ideas why it is not working on the "Normal" position? After it warms up starts almost right up with the first turn of the key. I do know that the normal position is suppose to allow more fuel in and when something inside the prime switch warms up it's suppose to go back to normal intake for fuel.
