I really appreciate your help very comprehensive. I will pull the tank and look at that. I have other magnum 4 strokes 2x 52 and 2 x 91. All run great. I know this one will also when I find out what is causing this. There is no difference from about 1/2 throttle to WOT Engine stays the same. I wasn't sure if the valves needed to be adjusted or not
