Ok I had a carb that was not allowing my boat to take off and plane out. I sent the carb to Flyfishcarbs and they rebuilt it. I installed the carb back on and took the boat to the intercoastal waterway. It ran great for about an hour. It took off like it was supposed to and ran the best the boat has ever ran since i owned it. Then all the sudden it started spitting and spudering and before i could get the boat cut off we pulled the motor cover off and there was fuel bubbling out of the carb at the top and the overflow barb fitting. I was told by the rebuilder must have picked up a piece of trash and tried the few things they recommended like running carb out of gas and filling it back up a few times and pecking on the bowl. Well non of this worked so I took the card off and took the bowl off. I cleaned it al back out removing the needle and float. Put it all back together and put it back on and its still pushing fuel out of the little 90deg tube that dumps back into the carb in a straight flowing stream. What am i Missing or how do i fix this problem now???? I have 5psi coming out of the exterior fuel pump. Is it somehow when all hooked up building more pressure when running? The fuel pump is hooked up to the oil pressure switch so it only runs when engine is running.......... Please help!!! I only get 2 weeks vacation a year and this one is being spent working on my boat yet again. Thanks so much in advance. Joe
