I have a 50hp fourstroke BF 2000 year model. It wouldnt idle and bobbled at slow speeds so i removed, cleaned, re-installed, and synced all four carbs. Idles perfect! great throttle response, no coughing or bobbles on slow throttle up but now it wont go over 2800-3000rpm. Motor stills seems to be operating normaly. It just acts like im towing a barge. Did i screw up my jets?
