I have a 1985 18hp mercury xd. It runs fine all the way up to full throttle. At full throttle however it starts to run rough, vibrates, and I lose some power. I have used different fuel tanks and lines that i know work fine with other motors so i know its not that. Any ideas as to what is wrong? Thanks
