I have a '94 merc 90 HP. <br /><br />I'm having trouble with fuel. It is pouring out of the bottom carb. I blew the line out with air. It was OK for a little while then started leaking again. Yesterday I dropped the bowl off the bottom and cranked the motor for a while, then pushed the float up and the fuel stopped. I put the bowl back on and it started pouring out again when I cranked the motor. So, I pulled the carb off and the needle and seat look OK. <br /><br />Is there suppose to be a gasket on the needle?<br /><br />I am going to rebuild this carb at this point. I'm just checking to see if there is something that I am missing, or not checking?<br /><br />Thanks,<br /><br />Craig
