1994 Four Winns Vista 278 with two 5.0 Ford carbureted motors.
My port engine seems to smoke a lot at times with a thick, black smoke. It reeks of gasoline when idling and for a while after shutting down. I recently rebuilt the carb (2bbl Holley). Since replacing the carb it still smokes and smells. At WOT I am not achieving the 4200 rpms that it had easily achieved before the rebuild. There are no gas leaks.
The engine idles a little rough, which is one of the reasons for the rebuild. It had been starting well and running well at WOT before the rebuild. It does not use oil at all. I believe that the carb was rebuilt correctly. I did the other one last year with no problems. It still starts well.
My questions are as to why I am getting the rich condition. Could it be ignition related? Timing, possibly? I am also wondering why I am not getting my max RPM's. I am currently having trouble getting on plane. Could I have replaced the throttle cable incorrectly? It just doesn't seem as if I am achieving WOT.
Any guidance is appreciated. Thanks
