I have a 1996 Force 120hp that runs good until I try to go full throttle. I can get up to 5000 rpms and can run it for as long as I want but if I try to go full throttle then it boggs down and drops to around 4000 rpms. I have checked compression--all 120 or better. Changed plugs. Good spark at all cylinders. Removed hose from carbs and cranked engine and plenty of fuel coming out. I pumped bulb while trying to go full throttle but it made no difference. Tried choking it also-no increase. Had half a tank of gas that was a little old but put in 17 gals of fresh gas. Can't believe that it would run good at 5000 rpm if gas was bad--just my reasoning--doesn't mean it is right. Suggestions needed. Did remove carbs and sprayed with carb cleaner--didn't see how to remove jets--looks pressed in. Blew everything out with air.
Thanks in advance for suggestions. Not sure what to do next.
