I just bought an 03 23' fishmaster with an 03 dt225 2 smoke. The problem i am having is at idle, it starts right up but shutters and puffs whiteish blue smoke out the prop about every 5 seconds. it will do this for about 30 seconds to a minute then die. I thought, ok mabe its cold natured, but i brought it out to the lake and it runs awsome between 1800 and 5500 rpms. still dies at idle after its warmed up. I squeezed the primer bulb while it was idleing and every time it shutters and puffs the bulb pressure drops. the previous owner had the same problem and had the plugs changed and the tps adjusted, no difference. Any thoughts????
